What type of fire extinguisher must tow trucks have?

1-BC
2-BC
3-BC
4-BC

The correct answer is: 4-BC

Tow trucks are required to have a fire extinguisher rated at 4-BC. The rating of a fire extinguisher is determined by its effectiveness against different types of fires. The "B" designation indicates effectiveness against flammable liquids, such as gasoline and oil, which are particularly relevant in the context of tow trucks due to their operation and the vehicles they may encounter. The "C" designation indicates effectiveness against electrical fires, which can arise when dealing with vehicles that have electrical components. A 4-BC rating provides a larger capacity and more extinguishing potential than the lower ratings, making it suitable for the higher risks associated with towing operations. In emergencies, having a fire extinguisher that can handle both class B and C fires helps ensure the safety of the operator and any passengers or bystanders. Therefore, regulations mandate that tow trucks are equipped with this specific type of extinguisher to enhance safety on the road.
