Regular inspections and observations will be conducted by IRMASUD HSE FIELD SUPV to ensure JSA is being complied with. Daily Tool Box Talks will be undertaken to identify, control and communicate additional site hazards. Work must cease immediately if incident or near miss occurs. JSA must be amended in consultation with relevant persons. Amendments must be approved by IRMASUD/BG Management and communicated to all affected workers before work resumes.

Safety Notes 1. Fresh concrete has a very powerful caustic effect on skin owing to the alkaline nature of cement. Freshly mixed concrete, mortar, grout and slurry may cause skin irritation including alkaline burning and dermatitis.

2. The abrasive effects of sand and aggregate in the concrete aggravate the condition and effects range from dry skin, irritant contact dermatitis and allergic contact dermatitis to severe burns. 3. These burns can take several hours to occur and can be very painful. JSA NO:

Scale

Assessment

Description

3

High

The controls in place are weak and are not mitigating the risk. There is scope for significant improvement of controls.

2

Medium

The controls in place are partially mitigating the risk. There is scope for some improvement of controls.

1

Low

Controls are deemed to be able to reduce Residual Risk to a low level; Risk Response Action Plans being actively and successfully managed. There is little or no scope for improvement of controls.

Formwork checks before pouring.

Personal injury Falls Crush Hit by

Note: ‘Formwork’ includes: • the forms on which concrete is poured; • the supports to withstand the loads imposed by the forms and concrete; and • Any bracing added to ensure stability.

Legislation breach Litigation

Ensure: All materials and equipment used are fit for their intended purpose and meet design specifications. Formwork complies with the design. i.e. either a ‘formwork designer’ or a ‘professional engineer’s specification. Specifically: • Base is stable. • Suspended slabs are able to safely support loads that might be applied during pouring. • Frames, props and timbers are correctly spaced. • Joist and bearer sizes are correct. • Jack extensions are acceptable; and • There is adequate bracing to ensure stability.

Reinforcing mesh

Personal injury Strains and sprains; Eye injury

Manual handling: Ensure loads are light enough for individuals to carry or there is help available.

Electrical shock & fire hazard

Cutting/Welding Ensure safety glasses/ear protection is worn when cutting with bolt cutters or power grinder. Ensure all electrical tools are fit for purpose. Welders should ensure suitable eye protection is worn (welding mask) Where required a PTW (hot work) should be opened and fire hazards have been addressed – fire extinguisher, fire screen – spotter in place at all times Supporting mesh: Place reinforcing mesh supports, where required, in place on the day of the concrete pour to reduce tripping hazard

Concrete delivery – Suitable location:

Personal injury: Electric shock Struck by

Area to be: Easily accessible. Reasonably level with a firm base. Must be able to support the fully loaded delivery trucks. Must have clearance from obstructions, power lines and excavations. Traffic control where required – Example: When reversing, low clearance, obstacles, tight access or high vehicle and/or pedestrian traffic situations.

Concrete Pumping

JSA NO:


Personal injury: Struck by

Ensure: No people, other than those workers directly involved in the concrete pumping/Mixing operation, are in the operational safety zone. End hose is fitted with a suitable stop or end cap if it is being manoeuvred over people. Hopper grill is in the closed position. Pump flow rates match discharge rates of concrete delivery trucks. That the directions of the hose-hand are followed.

Concrete working and placement

Personal injury: Sprains and strains Fatigue Skin rash or allergy/dermatitis; Concrete burns

Ensure: PPE fits correctly – Example - waterproof boots should be high enough to keep concrete from flowing into them. Formwork maintains line, level, plumb, shape, etc during concreting. Placing concrete: Note – To reduce manual handling concrete should be placed as close as possible to its final destination. Shovels - Square ended shovels are recommended for evenly spreading concrete. (Round edged shovels will not spread the concrete evenly.) Flat, Even Sites - Start placing at the furthermost corner of the formwork from where the concrete is mixed or delivered. Always work towards the source of concrete supply, never away from it. Sloping Sites Start at the lowest point and work upwards to the highest point. Formwork – Do not exceed the maximum rate of permitted placement. Height - Not higher than required by the boxing. This will reduce the amount of manual handling of wet concrete. Do not lift concrete with a shovel, rather rake or push as required. Lift reinforcing mesh – where required - by pulling it up with a large hook to centre of the final slab.

Concrete working and placement – Continued

Concrete finishing

Personal injury: Sprains and strains Fatigue Skin rash or allergy/dermatitis; Concrete burns

Screed: Concrete by pulling a suitable aluminium or wood straight edge across the wet concrete. Screeding removes excess concrete and identifies low positions.

Personal injury: Sprains and strains

Note: Do not finish concrete while there is bleed water on the surface as this will increase the water to cement ratio which can cause crazing. Do not start final finishing until the concrete can support the weight of a person, leaving only slight surface imprints. Prevent indentations being formed in the concrete.

Bullfloat: Eliminates high and low spots and embeds large aggregate particles immediately after strike off. Should be finished before excess moisture or bleed water appears on the surface

Contract breach Poor concrete finish

Float / Trowelling: Floats are usually made of timber, trowels of steel. Use to even out any minor lumps on the concrete. Sweep it in an arcshaped motion, keeping the edge at the front of your sweep slightly raised, lest the float dig into the concrete.

On Completion – Stripping formwork / boxing

Personal injury: Crush

Sides: Can be removed after several hours to enable trowelling of exposed edges.

Structural collapse of poured floor

Floor: The time between pouring and formwork stripping depends on the job specifications, the cure required, and whether the form is supporting any weight, but is usually at least seven days after the pour has been completed. On Completion – Clean up

Personal injury: Concrete burns

Personal Hygiene: Wash all exposed skin – ensure coveralls are washed separately from other clothing, wash hands before eating Tools: Wash all tools Excess Concrete: Place in small stacks (about a shovel full) and allow to dry for safe removal. Empty cement sacks All empty bags/sacks are to be disposed of as per site instructions
