Key Hazards
- Roof or concealed-space fire from open flame and hot material
- Severe burns from asphalt, kettles, torches, and heated tools
- Propane leaks, damaged hoses, or cylinder exposure
- Fume and smoke exposure during heating and application
- Falls near roof edges while handling hot or bulky material
- Smoldering fire discovered after the crew leaves
2–3 Minute Talk Script
Torch-Applied Roofing and Hot Asphalt Safety requires workers to recognize the task-specific hazards before work begins and to use the controls established for the project.
The roofing plan should identify the approved system, hot-work authorization, combustible construction, propane and kettle setup, material routes, ventilation, fall protection, extinguishers, fire watch, and post-work inspection.
Combustible surfaces, insulation, voids, penetrations, parapets, and concealed spaces should be inspected and protected before flame or hot asphalt is introduced.
Propane cylinders, hoses, regulators, torches, kettles, valves, pumps, and temperature controls should be inspected, secured, separated from ignition and traffic hazards, and operated by trained workers.
Hot asphalt should be heated, transported, poured, and applied with equipment and PPE designed for splash, heat, and burn exposure, with routes kept clear and stable.
Fall protection and material staging should allow workers to control torches, buckets, rolls, and hoses without backing toward edges, tripping, or dragging equipment across access paths.
Fire extinguishers, emergency shutdown, first aid, fire watch, and repeated inspection of the roof and spaces below should remain in place for the required period after heat work ends.
Work should stop when wind affects flame control, propane is smelled, temperature control fails, combustible conditions cannot be protected, fall protection is compromised, or fire watch cannot be maintained.
Safety Reminders
- Complete hot-work and roofing-system requirements.
- Inspect combustible surfaces and concealed spaces.
- Secure and inspect propane and heating equipment.
- Use PPE for hot asphalt and burn hazards.
- Maintain fall protection and clear material routes.
- Keep extinguishers and emergency shutdown available.
- Continue fire watch and post-work inspection.
Ask the Crew
- What combustible roof and concealed spaces are present?
- Are propane, kettle, hose, and torch components inspected?
- How will hot material be moved without fall or splash exposure?
- What fire-watch and post-work period is required?
- What wind, leak, or temperature condition stops the work?
