What is the minimum UL rating required for a fire extinguisher when hauling hazardous materials?

5 BC
10 BC
20 BC
30 BC

The correct answer is: 10 BC

The minimum UL (Underwriters Laboratories) rating required for a fire extinguisher when hauling hazardous materials is 10 BC. This rating signifies that the extinguisher is suitable for use on Class B (flammable liquids and gases) and Class C (energized electrical equipment) fires, which are crucial in managing fires that could occur due to hazardous materials. Using a fire extinguisher with a rating below this minimum would reduce the effectiveness and safety when responding to potential fire hazards associated with hazardous materials. Therefore, a 10 BC rating ensures that the extinguisher has the capability to tackle the specific types of fires that might arise during the transportation of such materials, thereby promoting safe handling and compliance with safety regulations.
