Question 1

During demolition, what fire hazard is created by cutting through walls?

Accepted Answer

Cutting may expose hidden electrical wiring, gas lines, or create sparks that ignite dust and debris

Answer

Demolition work can expose live electrical circuits, breach gas lines, and generate sparks from cutting tools, all of which can ignite accumulated dust and combustible debris.

Question 2

What is the proper storage method for flammable liquids at a construction site?

Accepted Answer

In approved flammable liquid storage cabinets or designated areas away from ignition sources

Answer

Flammable liquids must be stored in approved containers within designated storage cabinets or areas, away from heat sources, electrical panels, and other potential ignition sources.

Question 3

What should a fire guard check regarding fire extinguishers during their patrol?

Accepted Answer

That they are charged, accessible, properly mounted, and have current inspection tags

Answer

Fire extinguisher checks should verify full charge (gauge in green zone), accessibility (not blocked), proper mounting, current inspection tags, and no visible damage.

Question 4

What is the fire safety concern with tarps and temporary enclosures at construction sites?

Accepted Answer

They can trap heat and fumes, restrict ventilation, and become fuel for fire if not fire-retardant treated

Answer

Non-fire-retardant tarps and enclosures can trap heat from temporary heating devices, restrict ventilation allowing gas accumulation, and serve as fuel if a fire starts.

Question 5

What is the maximum operating temperature for a portable propane heater at a construction site?

Accepted Answer

Per manufacturer specifications, typically with automatic shutoffs at 450-500°F surface temperature

Answer

Portable propane heaters must be operated within manufacturer specifications, which typically include automatic safety shutoffs to prevent surface temperatures from exceeding safe limits.
