What is the most common cause of fires during torch roofing operations according to FDNY fire investigation data?
Answer: Sparks or flame contacting combustible materials in concealed spaces (walls, roof decks, insulation)
Most torch roofing fires are caused by sparks or flame reaching concealed combustible materials — such as wood roof decks, insulation, or wall cavities — that smolder undetected before flashing over.
When storing propane cylinders at a hot work site, which of the following is a required safety practice?
Answer: Store cylinders upright, secured against tipping, and away from heat sources and ignition points
Propane cylinders must be stored upright, secured against tipping (to prevent valve damage), and kept away from heat sources, open flames, and ignition points to prevent leaks and fire.
What does the term 'hot work' refer to in the context of FDNY fire safety regulations?
Answer: Any work involving open flames, sparks, or heat sufficient to ignite surrounding materials
Hot work refers to any operation involving open flames, sparks, or heat generation sufficient to ignite combustible or flammable materials, including welding, cutting, grinding, soldering, and torch operations.
Which of the following best describes the fireguard's responsibility regarding combustible materials BEFORE torch operations begin?
Answer: Verify that all combustibles within 35 feet of the hot work have been removed, protected, or covered with fire-resistant materials
Before any torch is lit, the F-01 fireguard must verify that combustibles within 35 feet of the hot work point have been cleared, covered, or protected per NFPA 51B. This is a mandatory pre-work check.
An F-01 fireguard notices that a propane hose connecting the cylinder to the torch has a visible crack. What must be done?
Answer: Immediately shut down the torch, replace the hose before work resumes, and document the defect in the logbook
A cracked propane hose is a serious fire and explosion hazard. The torch must be shut down immediately, the hose replaced with a sound one, and the defect logged. Operations cannot resume with a defective hose.
What is the purpose of 'wetting down' the hot work area before and after torch operations?
Answer: To saturate exposed combustible surfaces (like wood) to reduce their susceptibility to ignition from sparks or radiated heat
Wetting down exposed combustible materials (wood decking, wood blocking, framing) before torch operations saturates them, significantly reducing their ignition risk from torch sparks and radiant heat.
