Which of the following is a characteristic of Class Charlie fire?

• A. Produces white smoke
• B. Produces blue smoke
• C. Produces black smoke
• D. Produces yellow smoke

Answer: (B)

Class Charlie fires involve electrical equipment and are often caused by energized electrical devices. One of the characteristics of a Class Charlie fire is the production of blue smoke. This blue smoke is a result of burning materials commonly associated with electrical components, such as plastic insulation from wires or circuit boards. Understanding the color of smoke can aid in identifying the type of fire and determining the appropriate firefighting approach. Blue smoke signals that the fire involves electrical materials, indicating the need for specialized extinguishing agents that do not conduct electricity, such as carbon dioxide or dry chemical extinguishers.
