What type and size of fire extinguisher must be required inside a school bus?

Inside a school bus, a fire extinguisher with a 1 quart capacity is mandated to ensure a swift response in case of fire emergencies. This requirement is rooted in the principle of providing adequate fire suppression capabilities while maintaining a manageable size for ease of access and handling by school bus personnel. A 1 quart chemical extinguisher is effective for small fires and can be easily stored in the bus without taking up excessive space.

This size and type of extinguisher strikes a balance between being sufficiently effective for the types of fires that may occur in a school bus setting, while also adhering to safety regulations that have been put in place to protect the safety of students and staff. Factoring in the limited space available on a school bus and the need for ease of use in emergencies, the 1 quart chemical extinguisher is the most appropriate choice.
