What is the required minimum number of fire extinguishers on a wheelchair bus?

The required minimum number of fire extinguishers on a wheelchair bus is based on safety regulations designed to ensure the protection of passengers and drivers in case of a fire emergency. A wheelchair bus typically carries a larger number of passengers and operates in various environments, increasing the risk of fire-related incidents. Therefore, having two extinguishers allows for better preparedness and response options in an emergency, especially when dealing with accessible features and ensuring that all individuals, including those with mobility impairments, can evacuate safely.

One extinguisher might not provide adequate coverage for a bus with multiple exits or if the fire breaks out in an area that is difficult to access quickly. Similarly, three or four extinguishers would exceed the minimum requirement, potentially leading to unnecessary weight or complexity without a substantial increase in safety. This is why the requirement is specifically set at two extinguishers for wheelchair buses.
