Which rating is specified for the crane extinguisher?

Explanation:
Fires around cranes can involve flammable liquids like hydraulic oil and fuels, as well as energized electrical equipment. An extinguisher rated for Class B and Class C fires is what you need to address those hazards. The numeric part of a BC rating shows how much Class B fire the extinguisher can handle in standardized testing; a larger number means greater extinguishing capacity. In a crane environment, you want the extinguisher with the higher BC rating because it provides more capability to control a sizable oil-based fire near live equipment. Lower BC ratings have less capacity and could be overwhelmed by a real crane fire. So the specified option is the one with the greater BC rating, giving the best chance to suppress a potential fire.
