F60 Hot Work Area Safety 2 — Questions and Answers
Question 1: Before torch operations begin, the fire guard must inspect the hot work area and ensure combustible materials are removed or protected within what minimum radius?
- 10 feet
- 25 feet
- 35 feet (Correct answer)
- 50 feet
Correct answer: 35 feet
FDNY regulations require combustible materials to be removed or protected within a 35-foot radius of the hot work area.
Question 2: During torch operations on a roof, the fire guard notices tar paper beneath the work area beginning to smolder. What is the FIRST action?
- Continue monitoring for open flame before acting
- Stop work immediately and extinguish the smoldering material (Correct answer)
- Notify building management and wait for instructions
- Increase ventilation to cool the surface
Correct answer: Stop work immediately and extinguish the smoldering material
Smoldering materials must be addressed immediately by stopping work and extinguishing the threat before it escalates.
Question 3: Which type of fire extinguisher is most appropriate for a hot work area where torch operations involve flammable gases?
- Class A water extinguisher
- Class B dry chemical extinguisher (Correct answer)
- Class D metal fire extinguisher
- Class K wet chemical extinguisher
Correct answer: Class B dry chemical extinguisher
Class B extinguishers are rated for flammable gas and liquid fires, which are the primary hazard during torch operations.
Question 4: A fire guard must remain on watch after torch operations cease. What is the required minimum watch period per FDNY regulations?
- 30 minutes
- 1 hour (Correct answer)
- 2 hours
- 4 hours
Correct answer: 1 hour
FDNY requires the fire guard to maintain a 1-hour watch after hot work ends to detect any smoldering or delayed ignition.
Question 5: When torch operations must occur near a wooden structural element that cannot be removed, the fire guard should ensure the element is protected with:
- Plastic sheeting secured with tape
- Wet burlap or fire-resistant blankets (Correct answer)
- Standard drywall panels
- Foam insulation board
Correct answer: Wet burlap or fire-resistant blankets
Wet burlap or fire-resistant blankets are approved protective coverings that shield combustible structures from torch heat and sparks.
Question 6: Which condition would make it UNSAFE to proceed with torch operations even after area preparation is complete?
- Ambient temperature above 80°F
- Wind speed exceeding safe limits that scatters sparks beyond the protected zone (Correct answer)
- The presence of a second worker in the area
- Use of a new torch not previously used at the site
Correct answer: Wind speed exceeding safe limits that scatters sparks beyond the protected zone
High winds can carry sparks well beyond the protected radius, creating ignition risks outside the prepared area and making work unsafe.
Question 7: A fire guard's hot work permit specifies the approved work location. If the operator moves the torch to an adjacent area not listed on the permit, the fire guard must:
- Follow the operator and continue monitoring
- Stop the work and require a new or amended permit for the new location (Correct answer)
- Allow the work if it looks similarly safe
- Document the change and report it after the job is done
Correct answer: Stop the work and require a new or amended permit for the new location
Hot work permits are location-specific; any change in work location requires a new or amended permit before operations continue.
