F01 Fire Safety and Prevention 2

Question 1

What is the most common cause of fires during torch roofing operations according to FDNY fire investigation data?

Accepted Answer

Sparks or flame contacting combustible materials in concealed spaces (walls, roof decks, insulation)

Answer

Defective propane cylinders exploding

Answer

Worker smoking near propane tanks

Answer

Electrical shorts from power tools used by other trades

Question 2

When storing propane cylinders at a hot work site, which of the following is a required safety practice?

Accepted Answer

Store cylinders upright, secured against tipping, and away from heat sources and ignition points

Answer

Store cylinders on their sides to prevent rolling

Answer

Store cylinders in enclosed rooms to protect from theft

Answer

Stack cylinders horizontally in pairs to maximize storage density

Question 3

What does the term 'hot work' refer to in the context of FDNY fire safety regulations?

Accepted Answer

Any work involving open flames, sparks, or heat sufficient to ignite surrounding materials

Answer

Any work performed during summer months when temperature exceeds 85°F

Answer

Only rooftop torch operations on residential buildings

Answer

Any work performed within 100 feet of a gas main

Question 4

Which of the following best describes the fireguard's responsibility regarding combustible materials BEFORE torch operations begin?

Accepted Answer

Verify that all combustibles within 35 feet of the hot work have been removed, protected, or covered with fire-resistant materials

Answer

Inform the contractor about combustibles and let them decide whether to move them

Answer

Combustible removal is solely the contractor's responsibility — the fireguard monitors only during operations

Answer

Survey for combustibles only if the building manager requests a pre-work inspection

Question 5

An F-01 fireguard notices that a propane hose connecting the cylinder to the torch has a visible crack. What must be done?

Accepted Answer

Immediately shut down the torch, replace the hose before work resumes, and document the defect in the logbook

Answer

Patch the crack with duct tape and continue work

Answer

Continue work at reduced flame pressure to minimize gas leakage

Answer

Report the hose condition to the contractor and allow them to decide

Question 6

What is the purpose of 'wetting down' the hot work area before and after torch operations?

Accepted Answer

To saturate exposed combustible surfaces (like wood) to reduce their susceptibility to ignition from sparks or radiated heat

Answer

To cool down the surface and make it easier for the torch membrane to adhere

Answer

To clean the surface of debris before the torch membrane is applied

Answer

Wetting is not recommended because it can damage roofing materials
