Match the following classifications of fires

• flammable metals

• Class A

• cooking materials

• Class D

• ordinary combustibles

• Class B

• energized electrical equipment

• Class C

• flammable liquids (gases)

• Class K

Which element is NOT in the Fire Triangle?

• Oxygen

• Fuel

• Carbon Dioxide

• Heat

This is considered the last stage of a fire (much of the fuel has been consumed and the temperature has decreased)

• Growth

• Decay

• Incipient

• Fully Developed

This is an early stage of a fire during which fuel and oxygen are virtually unlimited. The fire begins to influence the environment within the compartment.

• Growth

• Decay

• Incipient

• Fully Developed

This is the first stage of the burning process. The fire has not yet influenced the environment to a significant extent

• Growth

• Decay

• Incipient

• Fully Developed
