F04 Fire Hazard Recognition and Prevention Flashcards

During a patrol of a temporary event tent, you see a vendor refueling a gasoline generator while it is still running. What should you do?

Answer: Have the vendor shut down the generator and let it cool before refueling

Gasoline vapors can ignite on hot engine parts, so generators must be shut off and cooled before refueling.

Which item is the most serious fire hazard when found inside an occupied tent?

Answer: A portable propane heater with an open flame

Open-flame heating devices inside tents create a direct ignition source near combustible materials and crowds.

Decorations used in a place of assembly should be:

Answer: Flame-resistant or treated with an approved flame retardant

Decorative materials must be flame-resistant to slow fire spread in crowded spaces.

A fire guard notices several power strips plugged into each other to supply a vendor booth. This condition is called:

Answer: Daisy-chaining, an overload hazard

Plugging power strips into one another can overload circuits and cause overheating and fire.

Where should spare LP-gas (propane) cylinders be kept at an outdoor event?

Answer: Outdoors in a secured, ventilated location away from exits and the public

Spare LP cylinders should be stored outside, secured, and away from occupied areas, exits, and ignition sources.

Oily rags left in a pile in a maintenance area are dangerous mainly because they can:

Answer: Spontaneously heat and ignite

Oils oxidizing in rags can generate heat until they ignite, so rags belong in a covered metal container.

While patrolling, you find an exit door chained shut during an event. What is the correct action?

Answer: Have the obstruction removed immediately and notify the person in charge

Locked or obstructed exits are an immediate life-safety hazard and must be corrected at once.
