What type of fire extinguisher must be carried in a vehicle that transports passengers for hire?

A vehicle that transports passengers for hire must have a fire extinguisher that is effective against typical fire hazards associated with automotive environments. The chemical type extinguishers, often identified as dry chemical extinguishers, are versatile and can extinguish various classes of fires, such as those resulting from flammable liquids, electrical equipment, and other combustible materials found in vehicles.

The chemical type extinguisher is particularly advantageous because it can quickly quell fires that may arise from fuel leaks or electrical malfunctions, which poses a significant risk in vehicles. These extinguishers use substances like monoammonium phosphate, which can smother flames effectively and prevent re-ignition. This makes them suitable for the diverse environments encountered in passenger transport situations.

Other options, such as water-based extinguishers, might be ineffective against flammable liquid fires, as water can spread the fire. Foam-based extinguishers generally work well against liquid fires but may not always be ideal for vehicles due to the risk of electrical components. CO2 extinguishers are effective for electrical fires and can protect against re-ignition, but they may not cover all the potential hazards associated with vehicles transporting passengers for hire. Therefore, the chemical type extinguisher is the appropriate choice for
