What is the minimum capacity for chemical fire extinguishers in vehicles transporting passengers for hire?

The minimum capacity for chemical fire extinguishers in vehicles transporting passengers for hire is established to ensure safety standards are met. One quart is sufficient for the intended use in these types of vehicles, as it allows for effective management of small fires that could occur while transporting passengers. This size is portable and can be quickly deployed by the driver or any onboard personnel in case of an emergency.

Fire extinguishers need to be appropriately sized to permit quick action without being cumbersome, especially in a confined space like a passenger vehicle. Other capacities such as two quarts, three quarts, or one gallon exceed this minimum requirement, but they may not take into account the need for manageable weight and ease of use. Therefore, the regulation emphasizes that a one quart extinguisher meets the critical balance of functionality and practicality in passenger transport scenarios.
