Which extinguishing agent is specifically non-conductive?

Carbon dioxide (CO₂) is recognized as a specifically non-conductive extinguishing agent. This trait is critical when considering fire scenarios involving electrical equipment or live electrical systems. CO₂ works by displacing oxygen around the fire and interrupting the combustion process without introducing additional moisture or conductive substances that could exacerbate potential electrical hazards.

Water, while commonly used to combat fires, is a conductor of electricity and poses significant risks when applied in electrical fire situations. Dry foam, although effective in certain applications, can have components that may not be entirely non-conductive. Sodium bicarbonate, primarily utilized in Class B and C fires, can also present conductivity concerns under certain conditions. Hence, CO₂ is the best choice for non-conductive firefighting agents, highlighting safety and effectiveness in situations involving electrical fires.
