Commercial Driver License (CDL) Class B Practice Test

When using a fire extinguisher, what is the proper distance from the fire?

1. As close as possible to ensure accuracy

2. At a safe distance, as far away as possible

3. Standing directly above the fire

4. Within three feet of the fire

The correct answer is: At a safe distance, as far away as possible

Using a fire extinguisher at a safe distance is crucial for both effectiveness and safety. The proper approach is to start at a distance that allows you to assess the situation while keeping a safe buffer between yourself and the flames. This distance helps prevent the heat and smoke from affecting you, especially if the fire is larger than anticipated or if it starts to spread. Additionally, standing too close can lead to hazardous conditions, as you may become trapped if the fire spreads or if the flames change direction. As you use the extinguisher, you can always move closer as needed to direct the agent effectively, but starting at a safe distance ensures that you maintain an escape route while still being able to combat the fire.
