Which class of fire involves ordinary combustibles like paper and wood?
Class A fires involve ordinary combustibles such as wood, paper, cloth, and many plastics.
What letter represents a fire involving flammable liquids like gasoline?
Class B is the letter used to represent fires involving flammable liquids such as gasoline, oil, grease, and paint thinner.
Why should you never use a Class A (water-based) extinguisher on a Class C fire?
You should never use a Class A water-based extinguisher on a Class C fire because water conducts electricity and can cause a severe or fatal electrical shock to the operator.
.Which fire class is specifically found in commercial kitchens with deep fryers?
Class K is the specific fire classification for commercial kitchens involving high-temperature cooking oils and fats used in deep fryers.
Magnesium and Titanium fires belong to which classification?
Magnesium and titanium fires belong to Class D, which is the classification specifically for combustible metals.
True or False: A "Multipurpose ABC" extinguisher can be used on most common fires.
True
List the three components of the Fire Triangle.
The three components of the fire triangle are fuel, heat, and oxygen, all of which must be present simultaneously for a fire to ignite and continue burning.
Smothering a fire with a heavy blanket removes which part of the triangle?
Smothering a fire with a heavy blanket removes oxygen by preventing it from reaching the fuel source.
