• Class D

• Class A

• Class K

• Class C

________ fires consist of flammable liquids and gases such as gasoline, oil, and methane.

• Class C

• Class B

• Class D

• Class A

Which method of extinguishment interrupts the combustion reaction and stops flame production?

• Cooling with water

• Oxygen Exclusion

• Fuel Removal

• Chemical Flame Inhibition

An inspector's responsibilities include checking the installation and maintenance of standpipes and hose systems which:

• helps limit fire load and reduce the potential for fire growth

• allows the extinguishing system to interrupt a chemical chain reaction and exclude oxygen

• enables building occupants the opportunity to extinguish incipient fires

• provides emergency fire crews with the ability to disrupt combustion on elevated stories.

________ fires consist of combustible metals such as aluminum and magnesium.

• Class K

• Class C

• Class D

• Class B

Which of the following tasks that an inspector is responsible for enables a system to cool a fire and interrupt its chemical chain reaction?

• Verifying proper placement and maintenance of fire extinguishers

• Verifying that extinguishing systems are installed and functioning correctly

• Monitoring and regulating hazardous conditions

• Checking the installation and maintenance of standpipes and hose systems

During what stage is the fire releasing the maximum amount of heat possible for the available fuel and oxygen?

• Growth

• Fully Developed

• Incipient

• Decay

Which stage occurs when the oxygen concentration falls to the point that flaming combustion is diminished?

• Decay

• Fully developed

• Growth

• Incipient

The most common source of heat in combustion reactions is:

• light energy

• electrical

• chemical

• mechanical

Which of the following is one of the most common methods of fire control and extinguishment and works by reducing temperature?
