Write a toolbox talk on work at height

Work at height is one of the highest-risk activities on site, and falls remain a leading cause of fatal and serious injuries. The safest approach is to plan the job before work starts, identify where people or materials could fall, and choose controls using a hierarchy: eliminate the need to work at height where possible, then use passive protection such as guardrails and covers, then restraint systems, and finally fall arrest where exposure cannot otherwise be prevented. A site-specific fall protection plan should cover hazard identification, equipment selection, assembly, use, maintenance, dismantling, and rescue arrangements. [1] [16] [3]

• Typical fall hazards include unguarded edges, floor or roof openings, skylights, leading edges, damaged ladders or access equipment, improper scaffold construction, slippery surfaces, unmarked level changes, and work above dangerous equipment or impalement hazards.
• Unsafe acts that commonly lead to falls include working without fall protection, improper ladder use, leaning over guardrails, ignoring barricades, using makeshift platforms, and using equipment for purposes it was not designed for.
• Dropped object hazards must also be assessed wherever tools, materials, or debris could fall onto people below; establish exclusion zones, secure tools and materials, and prevent storage of loose items near edges.

[1] [1] [15] For regulatory compliance, fall protection requirements depend on the task and location. In the cited Washington construction guidance, protection is required regardless of height around dangerous equipment, floor openings, impalement hazards, boom-supported elevated work platforms, and certain confined-space work. Protection is required at 4 feet or more for many walking/working surfaces and related tasks, and at 10 feet or more for low-pitched roofing, leading-edge work, some non-walking surfaces, trenching/excavation, and scaffolding. Because trigger heights vary by jurisdiction and activity, workers must know the applicable rule for the specific task before starting. [2] [2] [2] [2]

• Use edge protection such as guardrails, covers, and barriers wherever feasible; these are preferred because they prevent exposure without relying on worker action.
• Guardrails should be installed at exposed edges, openings, platforms, and similar locations before work begins where practicable.
• Where guardrails cannot be provided, use a suitable personal fall restraint or personal fall arrest system matched to the task and anchor arrangement.
• Do not allow workers to work near unprotected edges, holes, skylights, or leading edges without a defined control method.

[3] [7] [16] Ladder and scaffold safety are fundamental. Select the right access equipment for the task, ensure it is in good condition, and never improvise with makeshift platforms. Workers must be trained in proper setup and use. Scaffolds are themselves a fall hazard category, so they must be erected, used, and inspected correctly, and fall protection may be required depending on the scaffold type and height. Ladders must be used only as intended, on stable footing, and workers should maintain three points of contact and avoid overreaching. [1] [1] [6]

When using a harness and lanyard system, the equipment must be appropriate, correctly fitted, connected to a suitable anchor point, and inspected before each use. A full-body harness is required as part of a personal fall arrest system. The dorsal D-ring should sit between the shoulder blades, the chest strap should cross the middle of the chest, and leg straps should be snug. Anchor points must be evaluated for strength, stability, and location, and used in accordance with legislation and manufacturer instructions. Never use damaged equipment, and remove any system from service after impact loading or if defects are found. [5] [5] [17] [9] [12]

• Inspect harnesses before each use for worn, frayed, cut, burned, cracked, deformed, or missing components, including stitching, webbing, buckles, grommets, and D-rings.
• Inspect lanyards, rope grabs, connectors, anchorages, and shock packs before use; remove defective items from service immediately.
• Inspect ladders, scaffolds, lifts, guardrails, covers, and anchor devices before use and after any event that could affect integrity.
• For elevating work platforms, complete pre-use inspections each shift and keep required manuals with the equipment.

[5] [17] [11] Risk assessment must be completed before work starts, reviewed immediately before the task, and updated whenever conditions change. Assess the work location, access and egress, surface condition, weather, nearby power lines, dropped-object exposure, rescue feasibility, and whether the selected controls actually prevent a fall. If the work is non-routine, high-risk, or involves multiple contractors, a permit-to-work system should be used to confirm hazards, controls, authorization, isolation needs, rescue arrangements, and competent supervision before anyone goes to height. [10] [9] [10]

Training and supervision are mandatory elements of safe work at height. Every worker must be trained to recognize fall hazards, correctly set up and use ladders, scaffolds, lifts, harnesses, and other protective systems, and understand site rules, trigger heights, dropped-object controls, and emergency actions. Supervisors must ensure only trained and authorized workers perform the task, verify inspections and permits are complete, stop unsafe work, and correct changing conditions immediately. [1] [7] [11] [14]

A written emergency rescue plan is essential for any work at height where a fall arrest system is used or where a worker could become stranded. Calling emergency services alone is not an adequate rescue plan. The plan must identify rescue methods, equipment, anchor points, communication methods, rescue team roles, first aid arrangements, access routes, and hospital transport. Rescue must be prompt because suspension trauma can develop within minutes and may be fatal in less than 30 minutes. Rescue drills and refresher training should be carried out regularly.

• Plan the work and complete a task-specific risk assessment and, where required, permit to work before starting.
• Use the hierarchy of controls: eliminate the hazard, install edge protection/guardrails/covers, use restraint where possible, and use fall arrest only when necessary.
• Select the correct ladder, scaffold, lift, harness, lanyard, and anchor system for the task and environment.
• Inspect all fall protection and access equipment before use; remove defective equipment from service immediately.
• Protect people below by securing tools and materials, setting exclusion zones, and controlling overhead work.
• Ensure workers are trained, competent, medically fit where required, and supervised by a competent person.
• Have a written, practiced rescue plan with equipment and trained rescuers available before exposure begins.
• Follow the applicable work at height regulations, manufacturer instructions, and site procedures at all times.
