Question 3

What is a Hot Work Permit, and when is it required?

Accepted Answer

Written authorization required before any work involving open flames, sparks, or heat that could ignite a fire, such as welding or cutting

Answer

A permit issued by the FDNY for any work performed in buildings above 75 feet

Answer

Documentation required when operating heating systems above their rated capacity during cold weather

Answer

An OSHA form required any time workers are exposed to temperatures above 90°F

Question 4

Before a Hot Work Permit is issued, which precaution should be verified in the immediate work area?

Accepted Answer

Combustible and flammable materials have been removed or protected from ignition sources

Answer

All electrical circuits serving the area have been de-energized

Answer

A sprinkler system is charged and operational directly above the work area

Answer

The work area temperature is below 70°F to reduce ignition risk

Question 5

How long after hot work is completed must a fire watch typically be maintained in the work area?

Accepted Answer

At least 30 minutes, and up to several hours depending on the materials present

Answer

15 minutes, as the risk of delayed ignition is minimal once work stops

Answer

Until the next business day when a supervisor can conduct a final inspection

Answer

No fire watch is required after work is completed if all sparks are extinguished

Question 6

A contractor cuts an 18-inch section of a wet sprinkler pipe to install a new branch line. The repair will take approximately 4 hours. Which action is the building's Fire Safety Director required to take?

Accepted Answer

Notify the FDNY of the impairment, establish a fire watch for the affected area, and restore the system as soon as the work is complete

Answer

No action is required because the contractor is responsible for fire safety during their own work

Answer

Reduce the building's occupancy load on the affected floor until the pipe is repaired

Answer

Disable all heat detectors on the floor to prevent false activations from pipe cutting
