In illustration D039SA below, which fire control plan symbol represents the agent or device best suited for extinguishing a class "C" fire?

Correct Answer: Option A — 26

Symbol 26 represents non-conductive gaseous or dry chemical extinguishing agents, such as CO2 or portable dry powder extinguishers, best suited for Class C energized electrical fires. Non-conductive media prevent fatal electrical shock to firefighting personnel operating equipment.
