Canadian Entry To Practice (CETP) Practice Test

What is the minimum size fire extinguisher rating that should be carried on a propane delivery vehicle?

1. 10 lb B:C

2. 18 lb B:C

3. 5 lb B:C

4. 20 lb B:C

The correct answer is: 18 lb B:C

The minimum size fire extinguisher rating that should be carried on a propane delivery vehicle is determined by the potential fire hazards associated with propane. Propane is highly flammable, and when delivering it, there is an increased risk of leaks and fires. A fire extinguisher with an 18 lb B:C rating is suitable because the B classification indicates that it is effective against flammable liquids such as propane and gasoline. The C classification signifies that it is safe for use on electrical fires. The size of 18 lb represents a significant amount of extinguishing agent, which ensures that adequate firefighting capability is available in the event of a fire. This rating helps ensure compliance with safety regulations and adequately protects both the delivery personnel and the public during propane transport. Smaller extinguishers may not provide enough capacity to effectively deal with a larger fire or multiple incidents, which is why an 18 lb fire extinguisher is the recommended standard for propane delivery vehicles.
