EASY Question #82:

Why are there different types of hand fire extinguishers on board? What is the reason for having different types of fire extinguishers on board? For what purpose are multiple types of hand fire extinguishers provided on board?

Answer:

Different extinguishers are designed for different classes of fire. Halon extinguishers are used for flammable liquid and electrical fires. Water extinguishers may be used for paper and fabric, but are not safe for electrical fires. Having multiple types ensures the crew can fight a specific fire during the flight.
