1 Scope EN IS0 14122 defines the general requirements for safe access to machines mentioned in EN 292-2.Part 1 Of EN IS0 14122 gives advice about the correct choice of access means when the necessary access to the machine is not possible directly from the ground level or from a floor. This part of EN IS0 14122 applies to all machinery (stationary and mobile) where fixed means of access are necessary. This part of EN IS0 14122 applies to means of access which are a part of a machine. This part of EN IS0 14122 may also apply to means of access to that part of the building (e.g. working platforms, walkways, ladders) where the machine is installed, providing the main function of that part of the building is to provide a means of access to the machine. NOTE This part of EN IS0 14122 may be used also for means of access which are outside the scope of this part of EN IS0 14122. In those cases the possible relevant national or other regulationsshould be taken into account.

Significant hazards

The significant hazards to be considered when determining the type and location of the means of access are the following: a)

Falling.

b) Slipping. c)

Tripping.

d)

caused by excessive physical effort, e.g. from climbing a series of ladders.

e)

from falling of materials or objects when they may cause a risk to persons.

Other hazards generated by the machinery, e.g. caused by the functioning of the machinery (moving parts of the machine, movement of the machine itself (mobile machines), radiation, hot surface, noise, steam, hot liquids) or caused by its environment (harmful airborne substances) are not covered by this part of EN IS0 14122 but the designer of the machine should consider them, e.g. by preventing the access. NOTE

EN 1050 gives principles for risk assessment.

This part of EN IS0 14122 is primarily aimed at the prevention of persons falling and of excessive physical efforts.

5

Requirements for the selection of the fixed means of access

5.1 General There shall be a safe and convenient means of access to all the zones and points of the machine where the need for access can be foreseen during the phases of the "life" of the machinery (see 3.1 1 of EN 292-1:1991).



Page 8 EN I S 0 14122-112001 5.2 Preferred means of access The preferred means of access to the machinery shall be in the following order : a)

access directly from the ground level or from a floor, (for more details see 5.3.1.1 and EN IS0 14122-2) ;

b)

lifts, ramps or stairs, (for more details see 5.4) ;

c)

stepladders or ladders, (for more details see 5.5).

5.3 Selection of the means of access 5.3.1

Basic solutions

Whenever possible, access to control devices and other parts of the machine is preferred from either a 5.3.1.1 ground level or a floor. This is particularly important where frequent access is required. If level access according to 5.3.1.1 is not possible or practicable,

5.3.1.2

-

a lift or

-

suitable ramp with an angle of pitch less than 10 O (see 5.4.b)) or

-

stairs with an angle of pitch from a minimum of 30 O to maximum of 38 O (see 5.4.c))

shall normally be selected as a safe and suitable basic solution for the necessary access.

5.3.2

Conditions for the selection of stepladder or ladder

5.3.2.1 In the design of access to machinery, stepladders and ladders shall be avoided as far as practicable due to the higher risk of falling and because of the higher physical efforts when using these access means. 5.3.2.2 If access means according to 5.3.1 are not possible, selection of a stepladder or ladder may be considered. The final decision shall be made on the basis of the risk assessment, including ergonomic aspects. If the level of risk (see EN 1050) is considered to be too high, the basic construction of the means of access to the machine shall be changed to allow accessways with a reduced risk to be used (see 5.3.1 and annex A). 5.3.2.3 The following list presents some examples of the cases when a stepladder or ladder may be selected. These are only examples - the final selection shall always be done case by case on the basis of risk assessment. In most cases more than one of the conditions in the following list shall be fulfilled to make the selection of a stepladder or ladder possible. a)

Short vertical distance.

b)

The means of access is foreseen to be used infrequently.

--`,``,```,,,`,``,,`,`,,,,,,,-`-`,,`,,`,`,,`---



Page 9 EN IS0 14122-112001

0

NOTE When estimatingthe frequency of the use, the whole life of the machinery is considered. If the means of access is to be used frequently, e.g. during the assembly or installation of the machine or during periodical major maintenance tasks, a stepladder or ladder is not an adequate solution. c)

The user will not be carrying any large tools or any other equipment when using the means of access.

d)

Only one user will be foreseen to use the means of access at the same time.

e)

The means of access is not foreseen to be used for evacuation purposes by injured persons.

f)

The structure of the machine does not make stairs or other basic means (see 5.3.1) possible.

NOTE

Examples are a tower crane and mobile machines.

5.3.2.4

For the choice between stepladder and ladder see 5.5.

5.4 Choice among lift, ramp or stair

O

The installation of a stair or ramp as means of access between two levels is always preferable to that of a stepladder or ladder. When selecting either a lift, ramp or stair, the following points shall be considered. a)

A lift may be the best solution in the following cases;

- need for frequent access of several persons;

-

long vertical distances;

-

heavy loads to transport;

An alternative escape route is always needed in addition to a lift. b)

A ramp may be the best solution in the following cases;

-

for a short vertical distance :

- where it is necessary to transport wheeled vehicles (forklift trucks, manually moved carts etc.).

O

Different angles of the ramp are depending on the use :

-

for hand carts or other manually transported wheeled vehicles, maximum angle 3 O (particularly when likely to be used by handicapped persons);

-

for motor vehicles (e.g. forklift truck), maximum angle 7 O ;

-

for walking, up to 20 O (generally and preferably not more than 10 O ) .

NOTE 1 Ramps are often preferable to stairs with only one or two steps. NOTE 2 The properties of the surface have very strong influence on the safety of the ramp. The surface should have very good resistance against slipping in particular for ramps between 10 O and 20 O.

--`,``,```,,,`,``,,`,`,,,,,,,-`-`,,`,,`,`,,`---



Page 10 EN I S 0 14122-1~2001 c)

Stairs (for detailed requirements see EN I S 0 14122-3). Preferred angle of pitch is between 30 and 38 O. O

5.5 Selection between stepladder and ladder When making the selection between stepladder and ladder at least the following points a) and b) shall be considered. For the detailed requirements of these means of access, see prEN IS0 14122-4:1996 (fixed ladders) and EN IS0 14122-3 (stepladders). a)

Consequences on the level of safety affected by the choice of stepladders;

-

if a person is coming down the stepladder and not facing it, there could be an increased risk of falling;

-

if a person is using the stepladder whilst carrying small objects, there could be an increased risk of falling;

-

according to EN IS0 14122-3, the maximum flight of a stepladder without a rest platform is limited;

-

stepladders with an angle of pitch between 60 O and 75 O should only be selected due to space limits or process requirements.

b) Consequences on the level of safety affected by the choice of ladders;

-

the person needs to face the ladder and also to use his hands for holding. Therefore, it is considered highly unlikely that the user will descend facing away from the ladder;

-

ladders are physically harder to use;

-

according to prEN IS0 14122-4:1996the maximum flight of ladders without a rest platform is limited;

- Two main alternatives for protection of the users of fixed ladders against falls from a height are safety cages or fall arresters: - The cage shall be the required choice, as it is a means which is always present and the actual level of

safety is independent of the operator's actions,

- Where it is not possible to use a cage, individual protective equipment shall be provided. The fall arrester is only effective if the user chooses to use it. If a harness with an incompatible sliding system is used with a guided type fall arrester, there will be a risk.

A fall arrester shall be designed only for low frequency and specialised access (e. g. maintenance). NOTE An appropriate individualfall protection device is able to arrest a fall better than a cage.

A.l Make changes in the position of pillars, beams, pipelines, cable trays, platforms, storage tanks etc., to make the use of stairs designed in accordance with this part of EN IS0 14122 or other preferable access means possible.

A.2 Make changes in the design of the means of access (e.g. location) to make stairs designed in accordance with this part of EN IS0 14122 or other preferable means of access possible. EXAMPLE 1 Make the access from another side so that there is enough room for stairs designed in accordance with this part of EN IS0 14122. Add horizontal platforms if necessary. EXAMPLE 2 Make changes in the design of the means of access so that stairs are possible (e.g. change in the direction).

EXAMPLE 1 Position lubrication points near the ground level with the help of pipes. EXAMPLE 2 Use a different method of lubrication, e.g.

-

permanent lubrication;

-

lubrication circuit with a pump.

EXAMPLE 3 Motor and power transmission means positioned so that access to the maintenance and servicing points is possible from the ground level. EXAMPLE 4 The machine is installed to another place so that access is possible e.g. from an already existing platform. EXAMPLE 5 Change the position of pipelines and/or valves so that operation of the valve is possible from the ground level or the floor.
