How many fire extinguishers are required in wheelchair buses with at least what rating?

The requirement for the number of fire extinguishers and their ratings in wheelchair buses is designed to ensure the safety of passengers and drivers in case of a fire emergency. The correct answer indicates that two fire extinguishers are required, each with a rating of at least 4 BC.

A rating of BC indicates that the extinguisher is suitable for fires involving flammable liquids and electrical equipment, which are relevant hazards in a transport environment. The specification that the extinguishers must have a rating of at least 4 BC signifies a need for adequate capacity to address a potentially larger or more severe fire. In the context of transporting passengers with mobility needs, including those who may require additional assistance during evacuations, having two extinguishers ensures that there is sufficient firefighting capability readily available in different areas of the bus.

This multifaceted approach contributes to overall passenger safety by providing multiple means of fire suppression, which is essential for preventing injuries and facilitating efficient evacuation if necessary.
