What type of fire extinguisher is required to be mounted in or around the cab of a mobile crane according to consensus standards?

The requirement for a fire extinguisher in or around the cab of a mobile crane is specifically related to ensuring that the equipment is equipped to combat potential fire hazards associated with its operation. The designation "10 BC" indicates that the extinguisher is suitable for combating Class B and C fires, which are particularly relevant in the context of mobile cranes due to the presence of flammable liquids and electrical equipment.

A fire extinguisher rated at 10 BC provides a balance of effectiveness and weight for use in a mobile environment. It is sufficiently rated to tackle fires caused by flammable gases, liquids, and electrical equipment without being overly cumbersome, which is critical for operators who may need to access it quickly during an emergency situation.

The other options reflect various sizes or capacities of fire extinguishers that may be suitable for different applications, but they do not meet the required standard specified for cranes. Having an appropriately rated fire extinguisher is essential for safety compliance and personal protection in potentially hazardous situations encountered during crane operations.
