Which fire extinguisher rating is required for mobile crane operations?

• A. 10BC
• B. 5BC
• C. 2A 10BC
• D. 10A

Answer: (A)

In mobile crane operations the fire extinguisher chosen should match the hazards most likely to occur, mainly fires from flammable liquids and from electrical equipment. That’s why you look for a rating that covers Class B and Class C fires. A BC-rated extinguisher is designed for those exact hazards, and the 10 in front of BC indicates a sufficient size to handle a modest oil or fuel fire before it spreads. An extinguisher that includes an A rating would address ordinary combustibles like wood or paper, which aren’t the primary risk in crane work. A smaller BC rating might not provide enough capacity for a real-world fire scenario, and adding an A rating isn’t necessary for this setting. Therefore, 10BC is the appropriate minimum.\
