Explanation:
A: There are five classes (A, B, C, D, and K) of fire. You need to know the differences among the types of fire so that you know how to properly extinguish each
type. Portable fire extinguishers have markings that indicate what type of fire they should be used on. A fire is a Class D if there are combustible metals on fire.
These metals can be magnesium, sodium, or potassium. These types of fires should be suppressed and extinguished with dry chemicals.
B is incorrect because a fire is a Class C if there is something electrical on fire. This can be computers or any other types of devices that run on electricity.
These types of fires should be suppressed and extinguished with a type of gas as in Halon or CO2.
C is incorrect because a fire is a Class B if there is something liquid on fire. This can be petroleum, tars, or oils. These types of fires should be suppressed and
extinguished with a type of gas as in FM-200 or CO2.
D is incorrect because a fire is a Class A if there is a type of common combustible material on fire. This can be wood, paper, or cloth. These types of fires
should be suppressed and extinguished with water or soda acid.
