On a non-wheelchair bus, what is the minimum fire extinguisher rating for one extinguisher?

The minimum fire extinguisher rating for a non-wheelchair bus is 2BC. The fire extinguisher rating system is based on the class and size of the fire that each extinguisher can handle. The letters indicate the type of fires (B for flammable liquids and C for electrical fires), while the numbers indicate the size or capacity of the extinguisher. In the case of a non-wheelchair bus, a 2BC rating signifies that the extinguisher can effectively combat small fires involving flammable liquids and electrical equipment.

The other ratings—4BC, 6BC, and 8BC—while still suitable, exceed the minimum requirement. Having a higher-rated extinguisher can provide greater protection, but according to regulation standards, 2BC is the minimum acceptable rating for this type of vehicle, ensuring that the necessary safety measures are in place without over-specifying equipment that may not be necessary for every non-wheelchair bus.
