F02 Hazard Recognition 2

Question 1

What is the 'fire triangle' composed of?

Accepted Answer

Fuel, oxygen, and heat

Answer

The fire triangle consists of three elements needed for combustion: fuel (something to burn), oxygen (usually from air), and heat (an ignition source). Removing any one element extinguishes the fire.

Question 2

What hazard does a hot work permit address?

Accepted Answer

Operations involving open flames, sparks, or heat near combustible materials

Answer

Hot work permits are required for operations like welding, cutting, grinding, and soldering that produce flames, sparks, or heat that could ignite nearby combustible materials.

Question 3

What is the most common cause of fire deaths in buildings?

Accepted Answer

Smoke inhalation

Answer

Smoke inhalation is the leading cause of fire deaths, as toxic gases and reduced oxygen in smoke can incapacitate and kill occupants before flames ever reach them.

Question 4

An F-02 Fire Guard notices accumulated dust on electrical equipment during a patrol. What is the concern?

Accepted Answer

Dust is combustible and can contribute to fire risk near heat-producing equipment

Answer

Accumulated dust is combustible and can ignite from heat-producing electrical equipment, sparks, or other ignition sources. Regular cleaning is a fire prevention measure.

Question 5

What is the primary hazard of storing propane cylinders indoors?

Accepted Answer

Leaking propane is heavier than air, accumulates at floor level, and creates explosion risk

Answer

Propane is heavier than air, so any leak will cause gas to accumulate at floor level where it can reach ignition sources and create a significant explosion hazard.
