Question 693 Deck Safety

The correct answer is D) water (cartridge-operated). Water is not an appropriate extinguishing agent for Class B fires, which involve flammable liquids and gases. Water can spread these types of fires, making them worse. The correct extinguishing agents for Class B fires are foam (stored-pressure type), carbon dioxide, and dry chemical extinguishers, as they are effective at smothering and interrupting the chemical reaction of these types of fires. Using water on a Class B fire could lead to the fire spreading, which is why it should not be used.
