USCG Third Assistant Engineer Practice Exam 2026 – Safety and Environmental Protection

Question: 1 / 400

What type of fire extinguisher is suitable for electrical fires?

Water-type extinguishers

Foam extinguishers

CO2 extinguishers

CO2 extinguishers are suitable for electrical fires because they work by displacing oxygen around the fire while also cooling the flames. This makes them effective for extinguishing fires involving energized electrical equipment, such as wiring, circuit boards, and appliances. The non-conductive nature of carbon dioxide means that it can be used safely on electrical fires without the risk of electrocution.

In addition, CO2 extinguishers leave no residue, which is advantageous when dealing with sensitive electronic equipment, as opposed to some other types of extinguishers that may cause damage or require extensive cleanup. Their effectiveness in these situations makes them a preferred choice onboard vessels and in industrial settings where electrical equipment is prevalent.
