What class of fire extinguisher is required to be kept in the cab or on the machinery platform as per ASME B30.3?

The requirement for a fire extinguisher in the cab or on the machinery platform according to ASME B30.3 specifies a 10BC class fire extinguisher. This classification, indicated by "BC," signifies that the extinguisher is suitable for suppressing fires involving flammable liquids (Class B) and electrical fires (Class C).

Choosing a 10BC extinguisher ensures that it has a sufficient capacity to effectively combat potential fires that could arise in the work environment of a tower crane operator. The number "10" indicates the size or capability of the extinguisher, denoting that it has a minimum effectiveness and is appropriate for the typical risks associated with construction and crane operation.

Other classifications such as 5BC or 20BC do not meet the optimal specification of a 10BC extinguisher for crane operation. A 20BC extinguisher, while effective for larger fire incidents, may not align with the standard guidelines for extinguishers specifically required in crane cabs, which prioritize size and effectiveness. An ABC extinguisher, although versatile, might not be the primary recommendation for the specific hazards present in the crane operation context as outlined by ASME standards. Thus, maintaining a 10BC exting
