- A.
4 minutes
- B.
3 minutes
- C.
2 minutes
- D.

Where should fuel-soaked rags be placed after use?
- A.
Solid waste disposal pits
- B.
Containers filled with water
- C.
Self-closing metal containers
- D.
Hazardous waste storage area
Correct Answer
C. Self-closing metal containersExplanation
Fuel-soaked rags should be placed in self-closing metal containers after use. This is because self-closing metal containers provide a safe and secure way to store and dispose of flammable materials like fuel-soaked rags. These containers are designed to prevent the escape of vapors and minimize the risk of fire or explosion. Placing the rags in solid waste disposal pits, containers filled with water, or hazardous waste storage areas may not provide the same level of safety and could potentially lead to accidents or environmental hazards.Rate this question:

- B.
Contact the base interior electric shop.
- C.
Locate a water-type fire extinguisher.
- D.
Disable the circuit.
Correct Answer
D. Disable the circuit.Explanation
When fighting an electrical fire, the first step should be to disable the circuit. This is important because it will cut off the source of electricity, which is crucial in preventing the fire from spreading and causing further damage. By disabling the circuit, the risk of electrocution is also minimized, making it safer to approach and extinguish the fire. Once the circuit is disabled, other actions such as using a fire extinguisher or contacting the base interior electric shop can be taken to fully address the situation.Rate this question:

Water pressure fire extinguishers are effective on which class of fire?
- A.
Class A
- B.
Class B
- C.
Class C
- D.
Class D
Correct Answer
A. Class AExplanation
Water pressure fire extinguishers are effective on Class A fires. Class A fires involve ordinary combustible materials such as wood, paper, and fabric. Water, being a cooling agent, helps to lower the temperature of the fire and suppresses the flames. It also helps to soak the fuel, preventing re-ignition. Therefore, water pressure fire extinguishers are suitable for tackling Class A fires.Rate this question:
