2. Task Step Analysis

The following table breaks down the task into sequential steps, identifies hazards at each step, and prescribes controls.

#	Task Step	Hazards	Controls
1	Conduct pre-task safety briefing and inspect work area	Unidentified hazards from previous trades Unstable ground conditions or debris	Walk the work area with crew; identify and document all hazards Clear debris and verify stable footing before staging materials
2	Set up and inspect scaffolding at work area	Fall from height during scaffold erection (12-foot working height) Struck by falling scaffold components	Erect scaffold per manufacturer specs; install guardrails before use per 29 CFR 1926.451(g) Establish exclusion zone below scaffold during erection; hard hats required
3	Stage materials and tools at elevation	Overloading scaffold platform Dropped tools or materials onto workers below	Do not exceed scaffold load rating; distribute materials evenly Install toe boards on all open sides; use tool lanyards for hand tools
4	Prepare substrate surface for membrane application	Chemical exposure from primers and adhesives Slip hazard from applied primer on walking surfaces	Wear chemical-resistant gloves and safety glasses; review SDS before use Apply primer in sections; maintain dry walkway on scaffold platform
5	Install roof membrane sheets	Leading edge fall exposure during membrane placement Heat burns from torch-applied membrane Ergonomic strain from repetitive bending and lifting	Maintain 6-foot warning line from leading edges; PFAS required within warning line per 29 CFR 1926.502(f) Wear heat-resistant gloves; maintain fire extinguisher within 20 feet Rotate workers every 2 hours; use mechanical lifting aids for rolls over 50 lbs
6	Seal seams and penetrations	Open flame near combustible materials Fume inhalation in enclosed areas	Fire watch during and 30 minutes after hot work per 29 CFR 1926.352 Ensure adequate ventilation; use respirator if ventilation is insufficient
7	Inspect completed work and perform quality check	Walking on unsecured membrane near edges Trips over tools and materials left in work area	Maintain fall protection during all inspection activities Clean work area before inspection walkthrough
8	Demobilize — disassemble scaffold and remove materials	Fall during scaffold dismantling Struck by materials during lowering	Disassemble scaffold from top down per manufacturer procedures; maintain tie-off Lower materials by hand or hoist — no throwing; maintain exclusion zone below
