Introduction Objectives By the end of this chapter, students should be able to explain the how the following apply to equipment inspection: State, Provincial and Federal laws and legislation applicable to inspection; ANSI (American National Standards Institute), or CSA (Canadian Standards Association) Standards for equipment inspection; and Manufacturer’s (i.e. DBI-SALA) requirements for inspection.

General

P

roperly functioning fall protection equipment is vital for every person that works at heights. This equipment is designed to arrest and protect a worker in case of a fall, so it is important to know how to properly inspect and care for your equipment. It is extremely important to follow the laws, standards, and manufacturer’s recommendations for inspections How important is the inspection process? …VERY! In this chapter you will learn about the CSA and ANSI standards, manufacturer’s recommendations, and the laws that pertain to workers, supervisors, and employers regarding equipment inspection. OHSA The Laws regarding Fall Protection equipment in the United States are covered under OSHA and State OSHA legislation. In addition to OSHA, the ANSI consensus standards may be applied for fall protection equipment inspection. In Canada, Provincial and Federal regulation, as well as CSA standards, dictate the need and frequency of inspections for fall protection equipment. Each State, and Province may have different legislation, applying to employers and employees, the typical for each are listed below:

Canada  Construction Regulation; and/or  Industrial or General regulation United States  OSHA 1926.502 Construction Standard  OSHA 1910.66 General Industry Standard In North America there are only minor differences in regulations, however, companies that work across states and provinces should ensure that they know these differences. Generally, most regulations state that the user of the fall arrest equipment shall inspect each component of the system prior to use. There are newer regulations in some States and Provinces, which state that the user must comply with the manufacturer and ANSI, or CSA requirements. As an employer or user of fall protection equipment, it is a requirement to understand and follow these regulations and standards. ANSI, CSA, and most manufacturers, state that each part of a fall arrest system must be inspected prior to use, and in addition to this, at least annually by a competent person other than the user. If the equipment has been subject to a fall, it shall be removed from service and discarded; or removed from service, labeled and stored; or returned to service if it has been authorized for reuse by a competent or qualified person according to the manufacturer’s recommendations. Standards:

United States - ANSI A10.14-1991 Z359.2 -2007

Full Body Harnesses Objectives By the end of this chapter, students should be able to:

Perform a full body harness inspection and name the four key inspection components. Explain the difference between a prior-to-use inspection vs. a CSA/ANSI, and manufacturer’s recommended inspection Use an inspection log sheet to record a harness inspection. Recommend criteria for harnesses storage, cleaning, and maintenance.

General

T

he full body harness is an integral part of the fall arrest system. Though designed ruggedly for practical use in the construction industry, the harness requires daily and annual inspections. Further, there may be legislative requirements in some locations that require more frequent inspections than the CSA and ANSI standards dictate. In the end, all of the rules and regulations are there to make sure that if you were ever to fall, your harness is going to work.

The four key components of the full body harness requiring inspection are: • • • •

Hardware Webbing Labels Stitching

FREQUENCY • • •

Before each use, by the user By a competent person, other than the user, at least annually The results of the inspection should be recorded

IMPORTANT: If the full body harness has been subjected to fall arrest or impact forces it must be immediately removed from service.

IMPORTANT: Extreme working conditions (harsh environments, prolonged use, etc.) may require increasing the frequency of inspections.

Inspection Criteria Hardware: is any integral metal and plastic component on the harness: •

• • • • •

Dorsal D ring Dorsal back pad Buckles Keepers D, L, P, E, positioning rings

Webbing: is the synthetic fiber straps that makeup the harness; all stitch patterns and webbing must be checked for: • Frays • Cuts • Broken fibers • Tears • Abrasions • Mold • Burns • Discoloration • Holes • Or any other damage

Step 5. Record the inspection date and results in the company inspection and maintenance log, and check off the inspection box on the label attached to the harness. If inspection reveals a defective condition, remove unit from service immediately and destroy. NOTE: Only DBI-SALA or parties authorized in writing may make repairs to this equipment.

MAINTENANCE, SERVICING, STORAGE Clean full body harness with water and a mild soap solution. Do not uses bleach or bleach solutions. Wipe off hardware with a clean, dry cloth, and hang to air dry. Do not force dry with heat. Store full body harnesses in a cool, dry, clean environment out of direct sunlight. Avoid areas where chemical vapors may exist. Thoroughly inspect the full body harness after extended storage. An excessive buildup of dirt, paint, etc. may prevent the full body harness from working properly, and in severe cases degrade the webbing to a point where it should be removed from service. More information on cleaning is available from DBI-SALA. If you have questions concerning the condition of your harness, or have any doubt about putting it into service contact DBI-SALA.

DBI-SALA - Supplemental Inspection Information Life Expectancy: DBI-SALA does not have a cut-off date for service life for its equipment. As long as the product continues to pass the inspection, the item can continue to be used. The Owner's User Manual should be consulted regarding inspection frequency, and details on inspections. Holes/Burns: In critical areas of the product such as lanyards, shoulder or leg straps on full body harnesses, or on strength members of a product, a hole or burn, larger than 1/16 inch diameter, shall be grounds for rejection. More than two through holes on the same strap, shall be grounds for rejection. Holes on less critical components, such as chest straps of full body harnesses, or wear pads on products, can be up to 1/4 inch diameter before the part is rejected. See "Heat Damage" section. In most areas, cuts in webbing exceeding 1/8 inch in length shall be grounds for rejections. In areas near the dorsal d-ring, cuts of any length are grounds for rejection. Stitching: More than two ripped or cut stitches, within the same stitch pattern, shall be grounds for rejection. Ripped or cut stitches may be an indication that the product has been impact loaded. Cleanliness: General dirtiness normally will not be grounds for rejection, unless the buckles and other moving parts of the product are not able to function properly. Paint on webbing can cause web fiber rupture when the part is flexed therefore, web coated with paint shall be rejected. Web soaked with oils or other fluids should be inspected closely. Product MSD sheets should be reviewed to determine possible effects on products. Heat Damage: Areas damaged by heat (brown, hard areas) sources (i.e., weld slag, flames, etc) shall be closely reviewed. Large concentrations of damage are grounds for rejection.

INSPECTION FREQUENCY:  Before each use, visually inspect according to manufacture and standards.  The snap hook or carabiner must be inspected by a competent person, other than the user, at least annually. Results of each formal inspection must be recorded according to legislative standards IMPORTANT: If this equipment has been subjected to fall arrest or impact forces, it must be immediately removed from service and destroyed, or returned to an authorized service center for repair.

New Design Requirements: As of November 2007, ANSI Z359.1 has specified new strength requirements for snap hook and carabiner gates. The new snap hooks and carabiners have a minimum tensile strength of 5,000 lbs. in the intended direction of the load. Further, the front of the gates will be able to withstand a load of 3600 lbs. and withstand a side load of 3600 lbs. Load Directions

MAKING CONNECTIONS: USE CONSIDERATIONS: When making a connection using a snap hook or carabiner, the mating connector must be compatible in size and shape, for the intended load direction for each hook. Improper loading directions can cause the hook to fail or the gate to open, releasing the load. Do not use hooks that will not completely close over the attachment object. Do not connect snap hooks to snap hooks, carabiners to carabiners, or snap hooks to carabiners. Do not install more than one snap hook or carabiner into a single connection ring or opening (except for emergencies). Do not connect snap hooks or carabiners to objects or openings that may abrade or wear the hook material. © Capital Safety 2008

1-800-328-6146

MHB123107

4-2

MAKING CONNECTIONS: When using a hook to connect to the anchorage connector, ensure roll out cannot occur. Rollout occurs when interference between the hook and mating connector causes the hook gate to unintentionally open and release. Self -locking snap hooks and carabiners should be used to reduce the possibility of roll out. Do not use hooks or connectors that will not completely close over the attachment object.

APPLICATIONS PURPOSE: There are many Anchorage Connectors in today’s market designed for a variety of personal fall arrest, restraint, and work positioning, suspension, or rescue systems. Tie-off adapters and scaffold chokers may be used as an anchorage connector for a horizontal lifeline if the system is designed, installed, and used under the supervision of a qualified person. Do not hang, lift, or support tools or equipment from this equipment. Kevlar web tie-off adapters should be used when working with high temperature tools or materials, or in high temperature environments (foundries, chemical manufacturing, steel fabrication, emergency rescue services, fire services, welders, oil industry, and nuclear industry). STRUCTURE: The structure to which the anchorage connector is attached must be free of corrosion, cracks, deformities, or other defects that may weaken the structure. Do not attach an anchorage connector to a vertical structure unless a means of restraining the connector from sliding down the structure is present. If the anchorage connector were to slide down the structure in a fall arrest situation, serious injury to the user is possible. CONNECTING TO THE ANCHORAGE CONNECTOR: The connection to the installed anchorage connector must be with a self-locking snap hook or self-locking carabiner only, for tie-off adapters, connect your subsystem to the small D-ring only. Do not use a knot to connect a lifeline to the anchorage connector. Do not pass lanyard or lifeline through the anchorage connector Dring and hook back into lanyard or lifeline. Ensure connections are fully closed and locked. When using an energy-absorbing lanyard, connect the energy absorber "pack" end to the harness. Ensure self -retracting lifeline is positioned so that retraction is not hindered. Always protect lifeline or lanyard from abrading against sharp or abrasive surfaces in your work area.

Do not attach sub-system to both D-rings on tie-off adaptor Do not leave slack in the anchorage connector. WARNING: The anchorage connector must be tight against the anchoring structure. Do not leave slack in the tie-off adapter, this may increase the free fall distance in the event of a fall.


1-800-328-6146

WARNING: The tie-off adapter small D-ring must pass through the large D-ring. The connecting subsystem must be connected to the small D-ring only. Do not attach the subsystem to both D-rings.

Chapter

Self-Retracting Lifelines (SRL)

6

Objectives By the end of this chapter, students should be able to: Perform inspections on Types I, II, and III SRL’s. Use an inspection log sheet to record the SRL inspections.

General: Self Retracting Lifelines may be divided into three categories: Type 1: 10 feet and shorter with typically an external shock absorbing system, Type 2: 10 feet and over, generally having an internal shock absorbing system, Type 3: Type Two self retracting lifelines with a retrieval mechanism. This chapter will look at the inspection requirement for each category. APPLICATIONS PURPOSE: DBI-SALA self-retracting lifelines (SRL) are designed to be components in personal fall arrest systems (PFAS). They may be used in most situations where a combination of worker mobility and fall protection is required (i.e. inspection work, general construction, maintenance work, oil production, confined space work, etc.). Some SRL models incorporate a built-in retrieval feature. These models have the same fall arrest capabilities as those described above when used in their non-retrieval mode. In the retrieval mode, these models may be used for emergency rescue (raising or lowering) of personnel within the capacity range stated. It is also permissible to use retrieval models for raising and lowering of materials within the stated capacity range.

Step 6 Look for signs of corrosion on the entire unit. Step 7 WIRE ROPE: Inspect wire rope for cuts, kinks, broken wires, corrosion, chemical contact areas, or severely abraded areas. Slide up cable bumper and inspect ferrules for cracks or damage. NOTE: Replace the wire rope assembly if there are six or more randomly distributed broken wires in one lay, or three or more broken wires in one strand in one lay. A “lay” of wire rope is the length of wire rope it takes for a strand (the larger groups of wires) to complete one revolution or twist along the rope. Replace the wire rope assembly if there are any broken wires within one inch (25mm) of the ferrules. SYNTHETIC ROPE (Spectra and Technora): Inspect synthetic rope for concentrated wear, frayed strands, broken yarns, cuts, and abrasions. The lifeline must be free of knots throughout its length. Inspect for excessive soiling, paint build-up, and rust staining. Inspect for chemical or heat damage indicated by brown, discolored, or brittle areas. Inspect for ultraviolet damage indicated by discoloration and the presence of splinters and slivers on the rope surface. NOTE: All of the above factors are known to reduce rope strength. Rope strength is reduced proportional to the cross sectional area of the rope damaged. Damaged or questionable ropes must be replaced WARNING: Do not tie or knot lifeline. Avoid lifeline contact with sharp or abrasive surfaces. Inspect lifeline frequently for cuts, fraying, burns, or signs of chemical damage. Dirt, contaminants, and water can lower dielectric properties of the lifeline. Use caution near power lines. Step 8 Inspect connecting hooks for signs of damage, corrosion, and working condition. Swivel should rotate freely. Inspect impact indicator. Step 9 WIRE ROPE MODELS: Inspect reserve lifeline payout. If a fall has been arrested when most of the lifeline was out, it is possible that the reserve lifeline has been deployed. To inspect for reserve lifeline deployment, pull lifeline out of the SRL until it stops. If the reserve lifeline cable stop or cable guide sleeve is visible, the reserve lifeline has been spent, and the unit must be serviced by an authorized service center before reuse. If the reserve lifeline has not been deployed, that portion is acceptable and the inspection can continue.

SYNTHETIC ROPE MODELS (Spectra and Technora): Inspect reserve lifeline payout. If a fall has been arrested, it is possible the reserve lifeline has been deployed. To inspect for reserve lifeline deployment, pull lifeline out of the SRL until it stops. If the reserve lifelinewarning label is visible, the reserve lifeline has been spent and the unit must be serviced by an authorized service center before use. See Figure 14. If the reserve lifeline has not been deployed (the reserve lifeline label is not visible) that portion is acceptable and the inspection can continue. Step 10 Inspect each system component or subsystem according to manufacturer's instructions. Step 11 Record inspection results in the inspection log MAINTENANCE, SERVICING, STORAGE Periodically clean the exterior of the SRL using water and a mild soap solution. Position the SRL so excess water can drain out. Clean labels as required. Clean lifeline with water and mild soap solution. Rinse and thoroughly air dry. Do not force dry with heat. An excessive buildup of dirt, paint, etc. may prevent the lifeline from fully retracting back into the housing causing a potential free fall hazard. Replace lifeline if excessive buildup is present. Lifeline replacement, as well as additional maintenance and servicing procedures, must be completed by an authorized service center. An authorization and return number must be issued by DBI-SALA. Do not attempt to disassemble the SRL. Store SRL in a cool, dry, clean environment out of direct sunlight. Avoid areas where chemical vapors may exist. Thoroughly inspect the SRL after any period of extended storage.

Subject: Use of Rope Grabs in Flat or Sloped Roof Applications The use of DBI-SALA Rope Grabs (model 5001441, 5001442) on flat or sloped roofs is acceptable as a means of fall protection under most conditions. The following guidelines should be observed and the special conditions noted. 1. The rope grabs must be used on a lifeline, which meets the requirements specified in the user instruction manual (i.e., size, construction, material, and strength). 2. The anchorage point shall be capable of supporting 5,000 pounds for fall arrest or 3,000 pounds for restraint applications. See user instruction manual for additional anchorage strength information. NOTE: Restraint anchorage may only be used where there is no possible vertical free fall. Restraint anchorage does not have sufficient strength for fall arrest. 3. The rope grab shall be connected directly to the body support (via locking carabiner) or with a short lanyard (not to exceed three feet in length). 4. Provisions shall me made (i.e., warning guardrails, etc.) to prevent swing falls unprotected roof edges or corners.

Subject: Self-Retracting Lifelines on Flat Roofs Or Leading Edge Applications The use of DBI/SALA Self-Retracting Lifelines (SRL’s) for fall protection on flat roofs, leading edges, or similar applications where the SRL is not located overhead of the work area is acceptable under most circumstances provided special precautions are taken as described in this bulletin The following guidelines must be followed when using SRL’s in horizontal or near horizontal applications: 1. The SRL should be positioned on it’s edge, rather than laid flat, to prevent uneven spooling of the lifeline and to benefit retraction. Special brackets are available to support the SRL for some applications. 2. Swing fall hazards may exist, especially when working near corners, or out away from the SRL. Added fall clearance distances may be required, depending on the swing fall hazard. 3. The total fall distance will be greater than if the SRL were mounted overhead. Therefore, increased clearance distances will be required to prevent striking a lower level or obstruction. 4. A separate in-line energy absorber must be installed between the end of the lifeline and the harness to reduce the arrest forces resulting from falling over an edge. This energy absorber is connected in-line between the harness dorsal d-ring and the SRL’s snap hook. DBI/SALA offers a special model energy absorber (part number 1220362) for this purpose that includes a snaphook on one end and a D-ring on the other to ensure compatible connections can be made. Do not use energy absorbing lanyards for this purpose. See bulletin SRL002. 5. Sharp edges which the lifeline may contact during a fall could cut or damage the SRL’s lifeline. Sharp edges must be avoided or covered

over. Falls where the lifeline may slide along a sharp edge must be guarded against. 6. The cable extension speed must reach a speed of approximately 4.5 feet per second, before the brake will engage and a fall stopped. If a person fails to reach a speed of approximately 4.5 feet per second, the SRL will not engage, such as in a sliding fall down a sloped surface. 7. All applicable user instruction manuals should be reviewed and followed. 8. Employee training should be conducted to help assure a safe working environment.

Subject: Using DBI/SALA Self-Retracting Lifelines With Separate Lanyards For most applications, the use of separate lanyards connected in-line with DBI/SALA Self-Retracting Lifelines (SRL’s) is not recommended. There are several concerns regarding this lanyard/SRL combination, including: 1. Compatibility: The practices of attaching snap hook to snap hook, or snap hook to web/rope/cable loop is not recommended. This type of connection would not be compatible, and could cause rollout to occur, especially if the locking action on the snap hook does not function properly. 2. Free Fall: The addition of a lanyard in-line between the SRL snap hook and the user’s body support (i.e., harness) connection d-ring will potentially cause an undetected free fall if the fall occurs with the SRL fully retracted (but the lanyard is slack). The undetected free fall will produce greater fall energy and could extend the total fall distance considerably or damage the SRL, or both. 3. Fall Distance: An increase in the total fall distance will occur when a lanyard is used in-line with the SRL if free fall increases as described above. The extension, or stretch, of the lanyard may cause some of this increase. But, the majority of the increased fall distance is due to slack in the lanyard and the need to extend the fall arrest distance in absorbing the additional fall energy. Increased fall distances may allow the attached worker to contact a lower level or obstruction. 4. Retraction: The added weight of the in-line lanyard may overpower the SRL’s retraction spring. Reduced retraction can cause a slack line resulting in increased fall distances and increased arresting forces. A number of other concerns may apply to a specific application. If needed, a short (18 inches long) d-ring extension (model 1201117) can be used to help in the connection/disconnection of the SRL to the


7

body support. This d-ring extension provides a compatible connection point for the SRL snap hook. For applications where the SRL is anchored behind the user, and the line does not pay out vertically, the use of a separate, in-line energy absorber pack (i.e., model 1220362) can be used. Examples of applications where this would be used include flat roof work and leading edge work. See technical bulleting SRL001 for more information. All applicable user instructions shall be reviewed and followed. Employee training should be conducted to help assure a safe working environment. All DBI/SALA SRL’s contain built-in shock absorbing devices, which automatically reduce the arresting forces. Please contact DBI/SALA regarding applications that you believe requires an in-line lanyard.

Subject: Servicing / Inspection of Self Retracting Lifelines Servicing and inspection of mechanical fall protection devices, such as Self Retracting Lifelines (SRL’s) are important requirements of any effective safety program. The frequency of servicing/inspection as well as who should perform these activities are critical issues. SRL’s manufactured by DBI/SALA feature the highest quality U.S. made components. Second party testing and approvals are proof that DBI/SALA’s SRL’s are second to none. All applicable OSHA and ANSI standards are complied with as well, including the industry’s most stringent standard, ANSI Z359.1-1992. Manufacturing the highest quality SRL’s, and providing superior support has always been a priority with DBI/SALA. Our position is a proactive one; work with customers to make servicing and inspection more convenient and economical, and maintain the highest level of safety that is desired and deserved. The following questions and answers will help you further understand the issues relating to the inspection/servicing of SRL’s. How often should DBI/SALA SRL’s be serviced? There is no specified or required frequency for servicing and/or recertification of SRL’s. The work environment, the type of work being performed and the frequency of use are some of the factors that will determine how often the SRL should be serviced. The “Before Use Inspection” and the annual inspection by a Competent Person will help provide information on the SRL’s condition and indicate how often the SRL should be serviced. DBI/SALA is available to assist in determining the SRL’s service frequency needs. Our extensive servicing experience allows us to provide information to you that will help assure proper product performance. Why should I have my SRL serviced? Like any mechanical device, SRL’s will require some servicing or repair over time. Proper servicing at the appropriate time will help assure product performance and reduce overall cost of ownership in the long run. Servicing of SRL’s that have been impacted exhibit or contain other damage/defects will allow those SRL’s to be put back into use following repair.


9

When the “Before Use” inspection or the annual inspection by a Competent Person detects an unacceptable condition, authorized servicing will correct those unacceptable conditions and help assure proper product performance. What is actually done to a DBI/SALA SRL during servicing? The SRL is completely dismantled, cleaned and inspected. All components are checked for wear, corrosion or other damage. Parts are replaced only as needed. The critical energy absorbing brake element is re-calibrated to ensure performance. The label is replaced, as needed, and the entire unit is assembled and inspected. Certification is issued for each completed unit. What is typically found during a servicing/inspection? Approximately 40% of the time the lifeline needs to be replaced. This is the result of broken wires, bad kinks, or corrosion (wire rope models). On web lifelines often there is extreme wear/abrasion, cuts, burns or excessive dirt. The retraction spring approximately 25% of weak from prolonged primary functions and distance).

is also another critical area that is replaced the time. The springs may corrode or become use. Proper retraction is key to one of the benefits of an SRL (i.e., that of limiting fall

What does OSHA/ANSI require for servicing? OSHA AND ANSI regulations specifically address inspection of products such as SRL’s. The information found in the regulations covers inspections as follows: OSHA 1910.66

Remove impacted systems and components. Inspect systems prior to use.

OSHA 1926.502

Remove impacted systems and components. Inspect systems prior to use.

ANSI Z359.1-1992 Comply with manufacturer’s instructions. Inspected by user prior to use. Inspect at least annually by *competent person. Note: For Canada, the CSA standards require SRL's to be serviced within two years of the manufacture date, thereafter annually. *A competent person, as defined by OSHA, is one who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.


10

What is being done by DBI/SALA to make servicing of SRL’s easier and more economical at a reduced turn-around time?

Regional repair facilities are set up to provide more localized service. This will also help reduce the turn-around time. DBI/SALA has established a one-rate set service cost for some SRL’s. Set cost will continue to be developed for additional models. Are the components of competitive SRL’s more durable and longer lasting when compared to DBI/SALA?

No. DBI/SALA, in fact, uses only the most durable components in its designs. Critical components are made of hardened materials and treated or coated to prevent corrosion and increase life expectancy. In many cases stainless steel materials are used.

DBI/SALA’s exclusive patented sealed SRL design is a perfect example of what we do to extend the life of SRL’s and make them more durable. There is no other environmentally sealed SRL on the market today. What types of redundant, “back-up” features does DBI/SALA use and how does this compare to the competition?

DBI/SALA uses several “back-up” systems in its SRL’s. This includes multiple locking pawls, reserve lifeline features and anti-ratcheting designs. Most of the competitive units do not contain these systems.

Subject: Use of SRL's in Training Environments The use of DBI/SALA Self-Retracting Lifelines (SRL's) in a fall protection training environment allows for some special circumstances to apply. In particular, the DBI/SALA SRL may not need to be immediately removed from service following the activation of the impact indicator. The following guidelines should be observed for training applications where it is desired to continue using an impacted SRL. 1. An impact indicated SRL can only be used in training environments where there is control and monitoring performed on a regular basis. Other conditions typically associated with training include: a. Limited fall hazards. b. Trainee safety is foremost. c. Continuous supervision and instruction. d. Fall protection equipment is controlled and monitored and only used for training purposes. e. Fall protection equipment is only used according to manufacturing instructions. f. Manufacturers recommended servicing frequency guidelines be followed (i.e., SRL is serviced/recertified every two (2) years, minimum). g. Primary purpose of the activity is instructional. 2. A Competent Person must inspect SRL immediately after initial impact and all subsequent impacts. The inspection shall be performed in accordance with DBI/SALA instructions. Inspections include checking: a. Lock-up of the lifeline. b. Retraction of the lifeline. c. Lifeline condition. d. Snap-hook condition. e. Housing condition. f. Fasteners/hardware condition.


12

Any unacceptable conditions (excluding impact-indicating hook) shall require SRL to be removed from service immediately. 3. SRL shall be serviced/recertified by factory authorized personnel immediately following the conclusion of the session or program. 4. Trainees shall be informed of the special circumstances, which allow for impacted SRL to be used training circumstances only. 5. Documents/records shall be kept on file indicating: a. Date of first use for SRL. b. SRL service history. c. Quantity/circumstances of impacts. d. Inspections performed (when, by whom, findings).

Subject: Tag Lines for Self-Retracting Lifelines DBI/SALA recommends that a tag line be used to allow the line on a self-retracting lifeline (SRL) to fully retract back into the housing during extended periods of non-use. A retracting line that is paid out for extended periods of time may cause premature weakening of the SRL's retraction spring, therefore, effecting the operation of the SRL. 1. A tag line is a separate line that is used exclusively for allowing the SRL's line to retract back into the housing during non-use. The tag line is attached to the SRL's connecting hook and is long enough to allow the SRL line to retract in fully. 2. An extended period of time is defined as anything greater than a 24-hour period. 3. When using a tag line, the tagline should be controlled as the SRL's line is retracted back into the housing. Do not allow the tag line/SRL line to retract out of control (at a high rate of speed). 4. Depending on the work site environment and conditions, it may be necessary to restrain the free end of the tag line to prevent interference and entanglement with equipment or machinery. 5. Tag lines shall not be used directly for personal fall arrest, restraint, work position, personnel riding, or rescue applications. 6. Typical tag line materials include small diameter (3/16 inch to 1/2 inch) lightweight ropes made of materials such as polypropylene or nylon. 7. All applicable manufacturers’ instructions for the SRL shall be followed.

Subject: Self-Retracting Lifelines on Drilling and Service Rigs There is a recognized hazard where the available anchorage and necessary movement of a worker using a self-retracting lifeline (SRL) on a drilling and/or service rig is such that the cable or webbing of an SRL could come in contact with a structural edge of the rig (column and/or girder). The use of DBI/SALA SRL’s for fall protection on drilling and/or service rigs (or similar applications where the SRL is not located directly overhead of the work area and the risk of contacting a structural edge is apparent) is acceptable under certain circumstances provided special precautions are taken as described in this bulletin. The following guidelines must be followed when using SRL’s in areas where structural edges are in abundance: 1. Swing fall hazards may exist, especially when working near corners, or out away from the SRL. Added fall clearance distances may be required, depending on the swing fall hazard. Collision with objects during a swing fall should be guarded against. 2. The total fall distance may be greater than if the SRL were mounted directly overhead. Therefore, increased clearance distances will be required to prevent striking a lower level or obstruction. 3. Where the potential to impact on a structural edge exists, a separate in-line energy absorber must be installed between the end of the lifeline and the harness to reduce the arrest forces resulting from falling over an edge. This energy absorber is connected in-line between the harness dorsal d-ring and the SRL’s snap hook. If the harness being used does not have an integral shock absorber attached to the rear “D” ring, DBI/SALA and Protecta offers a special model energy absorber (part number 1220362) for this purpose that includes a snap hook on one end and a d-ring on the other to ensure compatible

connections can be made. DO NOT use energy absorbing lanyards for this purpose. See bulletin SRL002. DBI/SALA also offers a leading edge type SRL that contains heavier wire rope lifeline and a built in energy absorber for added protection against lifeline damage when contact is made with sharp edges. 4. Sharp edges which the lifeline may contact during a fall could cut or damage the SRL’s lifeline. Sharp edges must be avoided or covered over. Falls where the lifeline may slide along a sharp edge must be guarded against.

Subject: Top Bracket Anchorage Strength for Lad-Saf® Systems DBI/SALA recommends the following values as the required strength of the top bracket connection/support structure per number of users on the system: 1 2 3 4

person 3,375 persons 4,350 persons 5,325 persons 6,300

pounds pounds pounds pounds

These “anchorage” strengths were established as follows: 1. Dynamic testing on the system using a 100-kg sand bag and body belt gave maximum arresting forces at 1,300 pounds. 2. Static pretension in the carrier cable is assumed 750 pounds (per installation instructions). 3. A safety factor of 2 was applied to the dynamic Maximum Arresting Force (MAF). Result: 1 person system anchorage strength is (2 x 1,300) + 750 = 3,350 pounds. This figure was rounded to 3,375 pounds or 15 KN. For each additional user on the system, a figure of 975 pounds was added, representing the MAF of a human body (versus a san bag). An assumption was made that a human body would generate only 75% of the forces created by the sandbag. Therefore, a two person system anchorage is 3,375 + 975 = 4,350; three person system is 4,350 + 975 = 5,325; and 4 person system is 5,325 + 975 = 6,300 pounds. DBI/SALA is of the opinion that it is very unlikely on a vertical system that more than one user would fall at a time. Therefore, we have decided not to add additional safety factors onto the arrest loads of the second, third and fourth person attached to the system.


17

The anchorage strengths given here represent the minimum recommended values for newly installed systems. Environmental or use factors that could affect the long-term strength of the anchorage connection must be considered during installation and accounted for.

Subject: Corrosion Resistance of Ladder Safety System Wire Ropes The corrosion resistance of wire ropes used as the carrier component for ladder safety systems varies widely. Often the specific wire rope construction plays an important role in the ability to resist corrosion. The carrier cable is an important part of the cable ladder safety systems. The carrier must withstand the effects of the environment that it is installed in, for extended periods of time (often several years). Minimal maintenance is performed on the ladder safety systems once they are installed, making the corrosion resistance a critical safety issue for those using the system and relying on it to provide fall protection. Testing conducted on two different construction styles of 3/8 inch diameter galvanized wire rope has shown that significant corrosion resistance differences exist between a 1 x 7 construction and a 7 x 19 construction. Third party testing conducted by Stork /Twin City Testing Corporation has shown that a galvanized 1 x 7 construction will withstand over 5-1/2 times the duration of salt spray testing before red rust appears when compared to a galvanized 7 x 19 construction. The 1 x 7 construction has an average coating thickness of approximately 7 times that of the 7 x 19 construction.

Subject: Marking/Identifying Web Products Marking/Identifying various fall protection products (i.e., belts, harnesses, lanyards, anchorage straps, etc.,) made of webbing is appropriate as long as acceptable materials or processes are used. Information such as company name and inspection status is often applied to the product for proper identification. The following guidelines should be observed and the special conditions noted. 1. Inspection status/log labels applied to the product at the time of manufacture or inspection can be used to record inspection dates. Permanent markers which are water resistant and quick-drying (ex. Sanford Sharpie permanent markers) should be used. 2. Specific punches can be used on the inspection log label to represent a month the inspection was performed. The web should not be punched. 3. Separate identification tags/labels can be applied to the product. A location that will not interfere with the products performance should be selected (i.e., away from snap hooks, connecting rings, buckles, etc.). 4. The method of attaching separate identification tags should not affect the strength of the web. Riveting, punching holes and gluing the separate label to the web is not recommended in the field. Plastic or wire tie type fastener should be used. The fastener can be passed through or around a web or web loop (opening) for attachment. 5. Marking directly on the web can be performed with permanent type markers. Permanent markers which are waterproof/water resistant and quick-drying (ex. Avery Dennison Marks-A-Lot, Sanford Sharpie permanent marker) should be used. 6. Paint and/or paint pens should not be used to mark directly on the web. Paint can penetrate the web fibers, dry and cause the fibers to break when flexed.


23

7. Some types of permanent inks can be used to identify the product. Contact the factory for approval of specific inks. 8. Some solvents used in inks and other marking products can cause loss of strength in webbing, especially at elevated temperatures and high concentrations. Nitrobenzene, dichlorobenzene, phenol/tetrachlorethane, and benzyl alcohol as an example effect polyester fibers (used in most DBI/SALA web products). Contact the factory for approval of specific materials. 9. All applicable user instruction manuals for the products should be reviewed and followed. 10. Employee training should be conducted to help assure a safe working environment.

Subject: Capacity of Fall Protection Equipment All personal fall arrest equipment meeting the requirements of OSHA and ANSI Z359.1 is marked with a capacity limit of 310 pounds. Obviously, DBI/SALA recommends, whenever possible, this capacity limitation should be followed. In situations where the combined weights of the user’s body, tools, and clothing exceed 310 pounds, DBI/SALA will allow use of its equipment. However, caution must be used in applying personal fall arrest equipment for these situations. The following guidelines, and limitations, must be considered before use. 1. The Personal Fall Arrest System (PFAS) must incorporate a full body harness. The full body harness must be properly sized for the user. Sufficient strap length in adjuster buckle locations must be provided to assure the harness will not release. DBI/SALA recommends at least three inches of webbing extending beyond the adjuster buckle. 2. Other PFAS equipment, components, systems, or subsystems must be equally rated for capacity. 3. Anchorage must be capable of supporting at least 3,600 pounds without failure (engineered anchorage) or 5,000 pounds. 4. Only systems that include an energy absorber, Self-Retracting Lifeline (SRL), or other device to control fall arrest forces may be use. Simple lanyard systems must not be used. 5. Fall arrest systems should be rigged to minimize potential free fall. Free fall distance must not exceed six feet (refer to equipment instructions for free-fall limitations). 6. Arresting forces may increase. For example, in testing, using rigid steel weights, the following maximum arresting forces were observed for six-foot free fall drops using DBI/SALA model 1220006 shock absorbing lanyards:

Test weight – 220 lbs. (308 lbs.). MAF 810 lbs. Test weight – 230 lbs. (322 lbs.). MAF 816 lbs. Test Weight – 240 lbs. (336 lbs.). MAF 1,424 lbs. Test weight – 250 lbs. (350 lbs.). MAF 1,464 lbs. Test weight – 260 lbs. (364 lbs.). MAF 1,784 lbs. Test weight – 270 lbs. (378 lbs.). MAF 1,964 lbs. (Exceeded 1,800-pound limits).

Note: The value in parentheses is an estimated equivalent human body weight using the OSHA Conversion Factor of 1.4. Actual human arresting forces may be higher. Fall arrest distances may increase. In most falls, heavy users will experience extended fall arrest distances; shock absorbers for example could extend up to 42 inches, and rope grabs could have arrest distances up to 70 inches. Other energy absorbing components, such as SRL’s, could extend even further. Testing conducted using rigid steel weights on the DBI/SALA model 3103020 SRL gave the following results for “normal use” zero free fall drops: Test weight – 220 lbs. arrest distance 24 inches, MAF 632 lbs. Test weight – 300 lbs. arrest distance 32.5 inches, MAF 712 lbs. Test weight – 360 lbs. arrest distance 62 inches, MAF 760 lbs. 8. Equipment must be used, inspected, and maintained according to all other aspects of the User Instruction Manual provided with the equipment.

Subject: Compatibility of Fall Protection Equipment Compatibility refers to the harmonious operation between individual elements, as well as component subsystems. Typically the size and configuration of snap hooks, carabiners, d-rings and anchorage connectors are considered when addressing compatibility issues. Connectors are considered to be compatible with connecting elements when they have been designed to work together in such a way that their sizes and shapes do not cause their gate mechanisms to inadvertently open (rollout) regardless of how they become oriented. Do not use equipment that is not compatible. If the connecting element that a snap hook (shown) or carabiner attaches to is undersized or irregular in shape, a situation could occur where the connecting element applies a force to the gate of the snap hook or carabiner. This force may cause the gate (of either a selflocking or a non-locking snap hook) to open, allowing the snap hook or carabiner to disengage from the connecting point.

Small ring or other non-compatibly shaped element

Force is applied to the snap hook.

The gate presses against the connecting ring.

The gate opens allowing the snap hook to slip off.

DBI/SALA recommends equipment from one manufacturer be used as a system to help assure compatibility. DBI/SALA equipment is designed for use with DBI/SALA approved components and subsystems only. Substitutions or replacements made with nonapproved components or subsystems may jeopardize compatibility of equipment and may effect the safety and reliability of the complete system. Fall protection systems assembled from components and subsystems made by different manufacturers should only contain components that meet the requirements of applicable fall protection standards, such as ANSI Z359.1-1992; Safety Requirements for Personal Fall Arrest Systems, Subsystems and Components. Only use self locking snap hooks and carabiners. Self locking snap hooks and carabiners are required by ANSI Z359.1 and OSHA. Compatibility between elements and components (i.e., body supports, connecting components, anchorage connectors and anchorage points) of a fall protection system are critical to help assure safety to the user. Specific guidelines to follow when addressing compatibility issues include: 1. Read and understand all user instructions for the equipment involved. 2. The respective manufacturers shall be consulted and, necessary, perform the testing required by ANSI Z359.1-1992. 3.

if

Non-compatible connectors may unintentionally disengage. Snap hooks and carabiners shall be compatibly matched to their associated connector to reduce the possibility of rollout. Connectors must be compatible in size, shape, and strength.

4. Snap hooks and carabiners shall be securely closed and locked once coupled to a connector. 5.

The stability and compatibility of couplings between anchorage connectors and anchorage points shall be considered when selecting anchorage points and anchorage connectors. Connectors must be compatible with the anchorage or other system components.

6.

DBI/SALA connectors (snap hooks and carabiners) are designed to be used only as specified in each product’s user’s instructions. Use connectors that are suitable to each application.

7. Connectors shall be suitably sized and configured to interface compatibly with other connectors they will be attached to. 8.

Connectors (hooks, carabiners, and D-rings) must be capable of supporting at least 5,000 lbs. (22kN).

9. Fall Arrestors (rope grabs) shall be analyzed for compatibility with the lifeline it operates on. 10. Other factors to consider when looking at compatibility issues include impact forces, swing fall hazards, total fall distances, and free fall distances. DBI/SALA snap hooks and carabiners should not be connected:

A.

To a D-ring to which another connector is attached.

B.

In a manner that would result in a load on the gate.

NOTE: Large throat opening snap hooks should not be connected to standard size D-rings or similar objects which will result in a load on the gate if the hook or D-ring twists or rotates. Large throat snap hooks are designed for use on fixed structural elements such as rebar or cross members that are not shaped in a way that can capture the gate of the hook. C. In a false engagement, where features that protrude from the snap hook or carabiner catch on the anchor and without visual confirmation seems to be fully engaged to the anchor point. D.

To each other.

E. Directly to webbing or rope lanyard or tie-back (unless the manufacturer’s instructions for both the lanyard and connector specifically allow such a connection). F. To any object which is shaped or dimensioned such that the snap hook or carabiner will not close and lock, or that roll-out could occur.

Subject: Cleaning of Web Personal Fall Protection Products Personal Fall Protection Products manufactured from webbing can, and should be, cleaned periodically to help extend the life expectancy of the product and maintain an acceptable level of performance for the product. Because of the wide variation of cleaning processes available and the potential effect on performance, specific procedures have been established by DBI/SALA for DBI/SALA products, to help assure acceptable results. Justifi cation

Analysis of the product's cost vs. cleaning cost should be performed before proceeding with the process. Considerations include age of product, cost of cleaning and the estimated effectiveness of the cleaning process. As an estimate, the commercial laundering will cost approximately $2.50 to $5.00 per unit. The overall condition of the product should also be considered.

Scope

The cleaning processes and procedures specified in this bulletin typically apply to DBI/SALA's nylon and polyester webbing products used in Personal Fall Arest Systems (PFAS). Synthetic rope products, such as lifelines or lanyards, can be cleaned using similar processes. Rope type lanyards are typically more economical to purchase that most other fall protection products and, therefore, the justification to clean these items is difficult. The potential damage (i.e., wear, cuts, etc.) to rope lanyards in many applications also makes cleaning difficult to justify. Specialized web materials (Kevlar, elastic types, and reflective elements) and hardware materials/coating msut be analyzed prior to cleaning to determine effectiveness and potential damage from the cleaning process.

laundering is solely dependent on the cleanliness of product. Some applications may require weekly applications may require the product to annual basis

Effectiveness Laundering will be effective on the typical dirt and grease found in many industrial settings. Many paints, tar, and industrial chemicals cannot be completely removed from wht webbing. It is recommended that samples be laundered and inspected before a large quanitity is processed to determine the effectiveness of lanudering. Post laundering sample destructive testing may be appropriate if questionsexist regarding the product's ability to perform is designed. Contact DBI/SALA for post laundering evaluation and testing. Laundering Procedure Various procedures can be effective in cleaning web products. Highpressure power type washers and steam cleaners should be avoided when cleaning web products, because of potential harm to the web fibers. Two acceptable procedures are detailed below. 1. Hand Scrubbing: This procedure is effective for low volumes of equipment and can be performed internally at an economical price. The product can be soaked in water/cleaner solution before hand scrubbing. The scrubbing action will help break down the dirt, grease, or other material on the webbing. Once cleaned, the product should be rinsed in clean water and hung to air dry in a well-ventilated area out of direct sunlight. Never exceed 200° F. when drying. 2. Machine Wash: A top or side loading agitating style washing machine (commercial or consumer type) is acceptable for cleaning web products. The product should be placed in a mesh bag to prevent entanglement. A full wash and rinse cycle should be performed. Once cleaned, the product should be hung up to air dry in a well-ventilated area, out of direct sunlight. Never exceed 200° F. when drying.

Cleaning Agents A variety of cleaning agents is available. A mild detergent (bleach free) such as one used for laundering clothing is acceptable. For added cleaning power, a commercial/industrial strength-cleaning agent can be used. Recommended cleaning agents include: By Pas 1500 Series (Commercial laundry detergent) By Pas International Corp. P.O. Box 14 Hudsonville, MI 49426 Phone: (616) 875-7234

The cleaning agent supplier should be asked to supply appropriate information on the amount of cleaning agent to use and disposal instruction based on your procedure and the degree of cleaning required. Also, if consumer type washing machine is to be used, consult cleaning agent supplier for compatibility. Several of other cleaning agents is available on the market that may produce acceptable results. The cleaning agents listed have been reviewed and approved for use. DBI/SALA recommends cleaning agents not listed be reviewed by DBI/SALA for approval. Cleaning Agent Specifications The pH. level (acidity or alkalinity) of the cleaning solution should be no higher than 11 or 12. A pH. level higher than 12 may harm the webbing and effect the performance of the products. The water temperature, when laundering, should not exceed 160° F. Generally a wash temperature between 140° F. and 160° F. is recommended for safe, effective cleaning. Product Life

Parachute Buckle Specifications

Buckle Operation: The parachute buckle works by capturing the webbing between a knurled bar and the buckle frame. A spring-loaded slider bar maintains constant tension on the knurled bar. The webbing is woven into the buckle by passing the webbing up through the center slot of the buckle, over the knurled bar, then back under the outer

portion of the frame, folding back on itself. At least three inches of the free end of the webbing must extend out of the buckle, when used on leg straps, to maintain a safety factor in an impact situation. Pass the free end of the strap through a web keeper to allow the webbing to lay flat and be restrained. Do not cut excess webbing off the strap.

Buckle Adjustment: Pulling the free end of the webbing straight out away from the buckle will increase the tension on the strap. Tension can be released by pushing the free end of the webbing back toward the buckle and allowing the webbing to slip through the buckle. Loosening the strap can be facilitated by lifting the free edge of the buckle out to about a 90° angle from the body (to reduce friction on the knurled bar) and pulling it away from the body. Do not cut excess webbing off the strap. Buckle Release: The buckle may be removed from the webbing by continuing the tension releasing action until the webbing travels all the way through the buckle. (Note: The webbing is permanently attached to some parachute buckles, such as shoulder straps, and may not be removed.) Material: Frame, slider and knurled bar: AISI 4130 or 4140 alloy steel, heat treat: 35-42 Rc, in accordance with SAE AMS-H-6875A. Corrosion Resistance: Finish: zinc plate per ASTM B633-98, Type II, Class Fe/Zn 12, yellow. Strength: Buckle is capable of withstanding a tensile load of 4000 lbs. (17.8Kn) without breaking. Standards: OSHA 1910.66, OSHA 1926.502, ANSI A10.14-1991, ANSI Z359.1-1992. Pass Through Buckle Specifications

Buckle Operation: The pass through buckle is composed of two mating flat metal frames. The female frame is an open rectangle that is permanently attached to a loop at the end of a strap. The male frame is permanently attached to the joining strap by weaving the webbing through two slots in the frame. To engage the buckle, turn the male buckle at an angle so that it will pass through the female frame. After it has passed through, turn it back so that the male frame lies directly on top of the female frame. Buckle Adjustment: To adjust the tension on the straps to be joined by a pass through buckle, slide the male buckle frame up or down the webbing to lengthen or shorten the

strap to the desired length. Adjust the excess webbing through the 3 bar keeper to keep the webbing flat. Do not cut excess webbing off the strap. Buckle Release: To disengage a pass through buckle, force a portion of the male buckle strap up through the female frame until there is enough slack in the strap to allow the male frame to be turned to an angle that will allow it to pass back through and out of the female frame. Material: AISI 4130 or 4140 alloy steel or AISI 1541 carbon steel. Heat treat: 35-42 Rc, in accordance with SAE AMS-H-6875A. Corrosion Resistance: Finish: zinc plate per ASTM B633-98, Type II Class Fe/Zn 12, yellow or cadmium plate per Mil-QQ-P-416 F(2), Type II, Class 2, yellow chromate. Strength: Buckle is capable of withstanding a tensile load of 4000 lbs. (17.8Kn) without breaking. Standards: OSHA 1910.66, OSHA 1926.502, ANSI A10.14-1991, ANSI Z359.1-1992.

Tongue Buckle Specifications

Buckle Operation: The tongue buckle consists of a metal frame with a moveable tongue that lays down the middle of the frame. The frame is stitched into a loop at the end of a strap. The connecting strap is a piece of webbing that is pierced by grommets at regular intervals. To join the straps, pass the free end of the grommeted strap through the frame and pull the strap back at an acute angle to take up the slack in both straps. Allow the tongue to pierce the nearest grommet and tuck the free end of the strap through a web keeper. This will allow the webbing to lay flat and keep it from hindering movement or interfering with other equipment Buckle Adjustment: To adjust the tension on the strap, remove the free end of the strap from the web keeper and pull the strap back at an acute angel from the metal frame to release the tongue from its grommet. Hold the tongue out of the way and allow the webbing to pass back through the strap to loosen or pull more webbing through the frame to tighten the strap. When the desired tension is achieved, engage the tongue into the nearest grommet and tuck the free end of the strap back into the web keeper. Do not cut excess webbing off the strap. Buckle Release: To disengage, remove the free end of the strap from the web keeper and pull the strap back at an acute angle to the frame to release the tongue from its grommet. Hold the tongue out of the

way and allow the strap to pass back through the buckle frame until it exits completely. Material: Frame: AISI 4130 or 4140 alloy steel or cold rolled sheet or strip steel UNS 641300 per ASTM A505-87. Heat treat: 35-42 RC, in accordance with SAE AMS-H-6875A.

Tongue: 1018 Co steel in accordance with ASTM A510-96. Heat treat: 35-42 RC, in accordance with SAE AMS-H-6875A. Roller: Cold rolled steel, commercial quality, in accordance with ASTM A366/A366M-97E1. Heat treat: 35-42 RC, in accordance with SAE AMS-H-6875A. Corrosion Resistance: Finish: zinc plate per ASTM B633-98, Type II Class Fe/Zn 12, yellow, or Cadmium plate per QQ-P-416 F(2), Type II, Class 2 yellow chromate. Strength: Buckle is capable of withstanding a tensile load of 4000 lbs. (17.8Kn) without breaking. Standards: OSHA 1910.66, OSHA 1926.502, ANSI A10.14-1991, ANSI Z359.1-1992. Quick Connect Buckle Specifications

Buckle Operation: The quick connect buckle consists of two parts. The male portion is a metal tongue with flanges on the end. This portion is permanently attached to the end of a strap. The joining strap is woven through the receptor half of the buckle so the buckle can be positioned along the length of the strap. A plastic end cap keeps the buckle captive on the strap. To operate, insert the male portion into the receptor half of the buckle until a distinct click is heard. The noise is created by spring loaded latches that capture the

flanges on the tongue. A sharp tug on the strap will reveal whether the connection is complete.

Buckle Adjustment: To increase tension on the strap, while the buckle is engaged, lift the yellow plastic tab on the receptor away from your body with one hand while pulling the free end of the strap out from the buckle with the other hand. To decrease strap tension, pull the yellow plastic tab on the receptor out away from your body and allow the strap to slide back through the buckle. When the desired tension is achieved, tuck the free end of the webbing into the web keeper to keep it flat and to keep it from interfering with other equipment. Do not cut excess webbing off the strap. Buckle Release: To release the buckle, simultaneously squeeze the spring loaded metal latches toward each other with one hand and pull the male portion out of the receptor with the other hand. Depressing only one of the latches will not release the buckle; drop tests have confirmed this. Constant extreme tension on the strap (much greater than in normal use) would be required in order to allow the buckle to release when the latches on each side are depressed separately. Material:Top and bottom plates, release tabs and tongue: Cold rolled alloy steel UNS G41300 SAE AMS 6350. Heat treat 35-39 Rc. Knurled bar: Round steel bar UNS G10100, cold drawn per ASTM A108 Spring: Diameter .018 in. stainless steel spring wire, hard drawn, bright finish typw 302 or 304 per ASTM A313/A313M. Yellow plastic tab: Nylon, type 6. Corrosion Resistance: Finish: Cadmium plated per QQ-P-416, Type I, Class 1, or Zinc with clear chromate per ASTM 8633, Type II, Class Fe/Zn 12. Strength: Buckle is capable of withstanding a tensile load of 4000 lbs. (17.8Kn) without breaking. Standards: OSHA 1910.66, OSHA 1926.502, ANSI A10.14-1991, ANSI Z359.1-1992.

Subject: Cleaning of Carabiners MAINTENANCE AND SERVICING CARE: The connector may be cleaned with a mild detergent or disenfected with a mild sterile disenfectant. Locking mechanisms may be lubricated with a general purpose oil after cleaning. Cleaning and lubrication should be carried out after every use in a marine, drilling, or refinery environment. Store in a clean dry environment avoiding corrosive fumes or chemical substances. If gate operation is sluggish, apply a small amount of WD-40 or similar moisture repellant agent to the hinge end only. If you have questions concerning the condition of the snap hook or carabiner contact DBI/SALA. Additional maintenance and servicing procedures must be completed by an authorized service center. Authorization must be in writing. INSPECTION FREQUENCY: • Before each use, visually inspect according to steps listed below. • The carabiner must be inspected by a competent person, other than the user, at least annually. INSPECTION STEPS: Step 1.Inspect the carabiner for damage. Look carefully for cracks, sharp edges, burrs, dents, or deformities. Check for bending or distortion.

Step 2.Inspect the carabiner for excessive corrosion. The gate and lock should operate smoothly, with no difficulty. Gates must fully close and lock. Step 3.Inspect markings. Markings should be present and fully legible. Step 4.Inspect each system component or subsystem according to manufacturer's instructions. Step 5.Record the inspection date and results in the in the inspection and maintenance log in section 9.0. If inspection reveals a defective condition, remove the unit from service and destroy it, or contact an authorized service center for repair.

Standard/Regulation Information OSHA Steel Erection Safety Standard (Subpart R, 1926.750-1926.761) On August 13, 1998, a proposed Fall Protection standard for steel erection work (Subpart R) was published in the Federal Register. This proposed OSHA standard has been under development since 1994 and will, if approved, update the current regulations, which have been in place for 25 years.The final rule was published on January 18, 2001 and will go into effect on January 18,2002. This important fall protection standard will update the current regulations that have been in effect for over 25 years. The proposal will remain out for comment until November 12, 1998. All comments on the proposal will be heard at a hearing in December 1998. Following the hearing, the comments will be reviewed and a final rule issued later. Current Steel Erection Standards The current OSHA fall protection standard for steel erection work is very general in nature, typically not requiring fall protection until 25 foot or higher. Presently OSHA 1926.750-1926.752 requires nets to be used at 25 feet and above (when scaffolds are not used) and floor planking to be used (within two stories or 30 feet, whichever is less) below tiers of beams on which any work is being performed. The current standard also requires employees to be protected by safety belts when gathering and stacking temporary floor planking and when working on float scaffolds.

Who is effectedaffected by the new standard? The new standard would will apply to employees engaged in the erection, alteration, and/or repair of steel in single and multi story buildings, bridges, and other structures where steel erection occurs. This includes hoisting, connecting, welding, bolting, and rigging structural steel, steel joist and metal buildings as well as installation of metal deck, siding systems, misc. metals and ornamental iron. It is estimated that 39,000 structural metal workers perform these duties. The new standard would will not cover work on electric transmission towers, communication towers, broadcast towers and water towers or tanks (the new standard would will cover those working on the

structure that supports the tank). The current OSHA Subpart M standard (Construction Industry) does not apply to steel erection work, in terms of when and where to use fall protection. States with their own plans must adopt a comparable standard within 6 months of publication of a final rule. Formatted: Left

Connectors working between 15 feet and 30 feet must be given the means to tie-off. Connector determines when/if to tie-off. Forms of fall protection include perimeter safety cables, guardrails, nets, and personal fall arrest or fall restraint systems. Controlled decking zones (CDZ) may be established over 15 feet and up to 30 feet where metal deck is being installed. Training – Qualified person to train exposed workers in fall protection and to train exposed workers engaged in special, high-risk activities. The guardrails, nets, personal fall arrest systems and fall restraint systems specified in Subpart R must conform to the criteria set forth in Subpart M (1926.502). Major points of Subpart M criteria include: (This criteria would apply to Subpart R) Full body harness only for fall arrest. 1,800 pound maximum arresting force. Anchor points support 5,000 lbs. or provide 2:1 safety factor minimum when part of complete, engineered system. Six foot maximum free fall distance (exceptions do apply). Horizontal lifelines shall be designed, installed, and used under supervision of a qualified person, which maintains a safety factor of at least two. Summary

With the release of this standard, the steel erection industry will be regulated by a more detailed, up-to-date standard. This particular standard, which was created through the negotiated rulemaking process, is expected to prevent many deaths and lost workday injuries every year.
