Write a risk assessment for Reinforcement concrete and beam work

A suitable risk assessment and safe work method statement for reinforced concrete and beam work should require pre-task planning by a competent person, verification of structural design assumptions, inspection of formwork/falsework before and during the pour, controlled lifting operations, fall protection, rebar impalement protection, silica and cement exposure controls, and emergency arrangements before work starts. The work should not proceed unless temporary works, access, sequencing, and load paths have been reviewed and workers have been trained in the hazards and controls. [2] [5] [3]

Key hazards to identify

• Formwork/falsework collapse from inadequate design, missing bracing, overloading, eccentric loading, or excessive pour rate
• Structural instability of beams, walls, decks, and partially completed elements due to premature loading or inadequate temporary supports
• Falls from edges, deck perimeters, stairs, shaft openings, scaffolds, ladders, forms, and reinforcing steel
• Struck-by and caught-between hazards from pump booms, buckets, hoses, vehicles, falling materials, and stripping operations
• Impalement and laceration from exposed rebar, form pins, protruding bolts, nails, snap ties, and sharp edges
• Manual handling injuries from lifting, carrying, prying, pulling, pushing, and shoveling heavy materials
• Chemical burns, dermatitis, and eye injury from wet concrete and cement
• Respirable crystalline silica and cement dust exposure during mixing, cutting, drilling, grinding, sweeping, and cleanup
• Electrical hazards from overhead lines and use of electrical equipment in wet areas
• Slips and trips from wet concrete, debris, uneven ground, rebar, hoses, and poor housekeeping

[1] [3] [4] Safe work method statement controls

1. Plan the sequence of work: excavation/support, delivery routes, crane or pump locations, formwork erection, rebar fixing, embeds, inspections, pour sequence, finishing, curing, stripping, and back-propping. Do not load slabs, beams, or decks until a qualified person confirms capacity.
2. Assign responsibilities: supervisor, competent person, lifting supervisor/signal person, pump operator, formwork inspector, and emergency lead. Conduct pre-start briefings and toolbox talks.
3. Formwork and falsework: use only designed and structurally sound forms, shores, braces, ties, and wedges; erect to drawings; found on firm bearing; brace for vertical and lateral loads including wind, impact, cable tension, and unsymmetrical placement; inspect before pour and continuously monitor during placement. Stop the pour immediately if bulging, slipping, uplift, sagging, movement, leakage, or distress is observed.
4. Temporary supports: install back-propping, beam soffit supports, wall braces, and shoring as designed; protect against displacement; do not remove or alter supports without authorization; verify concrete strength before stripping or reshoring.
5. Lifting operations: use a lift plan for form panels, rebar bundles, beam cages, buckets, and accessories; inspect lifting gear; establish exclusion zones; use trained operators and signalers; control suspended loads with tag lines; never allow workers under suspended loads; maintain clearance from overhead power lines.
6. Work at height: provide safe access by stairs, ladders, scaffold towers, or work platforms; install guardrails and toe boards at edges and openings; cover or guard holes; use personal fall arrest, safety nets, or positioning devices where guardrails are not feasible; protect workers above impalement hazards.
7. Rebar installation: stack and secure bundles on firm ground; maintain clear access routes; cap or otherwise guard all protruding rebar that could cause impalement; use suitable platforms for tying and fixing; control falls when working on reinforcing steel at height.
8. Concrete pouring: confirm forms are clean, secure, and signed off; verify pour rate and sequence; avoid heaping concrete in one location; keep non-essential personnel out of the pour zone; use spotters for pump booms/chutes; check hoses, couplings, and outriggers; maintain communication between pump operator and placing crew.
9. Manual handling: use mechanical aids, team lifts, carts, cradles, and staged deliveries; reduce carrying distances; store materials close to point of use; avoid twisting while lifting; rotate tasks such as shoveling, vibrating, and stripping.
10. Exposure controls: suppress dust with water or local exhaust; avoid dry sweeping; provide washing and eyewash facilities; remove contaminated clothing promptly; prohibit eating and drinking in dusty areas; review SDSs for cementitious products and admixtures.
11. Housekeeping and access: keep decks, access ways, and stripping areas free of debris, loose materials, protrusions, and slurry; maintain lighting; barricade limited-access or stripping zones; prevent unauthorized entry.
12. Stripping and dismantling: strip only after authorization and confirmation of adequate concrete strength; maintain barriers below; remove loose debris first; lower materials in a controlled manner; never throw materials from height; maintain stability of remaining forms and supports throughout dismantling.

[5] [3] [4] PPE requirements

• Hard hat where there is risk of falling objects or contact hazards
• Safety glasses or goggles; add face shield where splash or flying particle exposure exists
• Alkali-resistant gloves suitable for wet concrete, preferably nitrile, butyl, PVC, or heavy-duty rubber as appropriate
• Long sleeves and full-length trousers or coveralls to prevent skin contact with wet concrete
• Waterproof or rubber boots with slip-resistant and puncture-resistant soles; tape pants over boots where needed to prevent concrete entry
• High-visibility clothing around plant, trucks, pumps, and lifting operations
• Hearing protection where pumps, vibrators, saws, or heavy equipment create high noise
• Respiratory protection when dust controls are insufficient or exposure may exceed limits, under a compliant respiratory protection program
• Kneepads or waterproof kneeling protection for finishing work
• Fall protection equipment where required for edges, forms, reinforcing steel, or platforms

[6] [10] [11] For work at height and reinforcing steel, OSHA-based controls should treat exposed rebar and lower-level impalement hazards as a combined fall-and-impalement risk. Employees working on the face of reinforcing steel 6 feet or more above lower levels must be protected by personal fall arrest systems, safety nets, or positioning devices, with the limited climbing allowance during rebar assembly construction recognized only under the specific conditions described by OSHA. Guardrails, covers, travel restraint, and properly inspected scaffolds or work platforms are preferred where feasible. [8] [7] [3]

Emergency procedures should include immediate stop-work authority, evacuation of the pour or stripping zone if instability is detected, rescue arrangements for falls, first aid for cement burns and eye exposure, and emergency response for struck-by, crush, or electrical incidents. If wet concrete contacts skin, wash immediately with clean water and appropriate soap and remove contaminated clothing. If concrete enters the eyes, irrigate immediately at an eyewash station and obtain urgent medical evaluation. Any sign of formwork movement, brace failure, unusual cracking, hose whip, or loss of support requires the pour to stop and the area to be isolated until assessed by a competent person or engineer. [9] [11] [3]

For compliance, the SWMS should reference OSHA 29 CFR 1926 Subpart Q for concrete and masonry construction, OSHA fall protection requirements including 1926.501, PPE requirements under 1926.95 and 1926.102, silica and respiratory protection requirements where applicable, and any state construction safety rules governing concrete forms, shoring, and impalement protection. At minimum, the document should include scope of work, sequence, hazards, controls, inspection points, competent person responsibilities, training, permits if needed, emergency contacts, and hold points for formwork approval, rebar inspection, pre-pour checks, and stripping authorization.
