What is the minimum BC requirement for a fire extinguisher on a school bus?

The minimum requirement for a fire extinguisher on a school bus is 5 BC; however, for clarity and consistency with regulations, the standard often referenced is a requirement of not less than 10 BC. This means that a fire extinguisher should have a minimum rating that indicates it is capable of putting out certain classes of fires, specifically those involving flammable liquids and electrical equipment, which could be relevant on a school bus.

A fire extinguisher rated at 10 BC indicates a higher capacity for extinguishing fires compared to lower ratings, ensuring that the safety equipment on the bus can effectively handle fire emergencies that might arise in this environment. Having adequate fire-fighting equipment is vital for ensuring the safety of students and staff.
