What does it mean if a fire extinguisher has a “B-C” rating?

A fire extinguisher with a “B-C” rating is specifically designed to combat Class B and Class C fires. Class B fires involve flammable liquids such as gasoline, oil, and paints, while Class C fires include those that involve electrical equipment. The “B-C” designation indicates that the extinguisher is effective for these types of fires, allowing users to safely extinguish a fire without the risk of electrical shock in the case of Class C fires.

This rating helps users understand the practical applications of the extinguisher in an emergency situation, ensuring that they select the right type of fire extinguisher based on the materials involved in the fire. It is essential to use the appropriate extinguisher to avoid exacerbating the fire or creating additional hazards. Thus, having a fire extinguisher with a “B-C” rating is crucial for safety in environments where flammable liquids and electrical equipment are present.
