• A. 5 BC
• B. 10 BC
• C. 15 BC
• D. 20 BC

Answer: (B)

The minimum BC rating for fire extinguishers required on trucks is indeed 10 BC. This rating indicates the extinguisher’s effectiveness in putting out fires involving flammable liquids and electrical equipment, which are critical safety considerations for vehicles like trucks that may transport hazardous materials or are outfitted with electrical systems.

A fire extinguisher's rating is determined based on its capacity and the type of fire it is designed to combat. The BC rating specifically denotes the extinguisher's capability against Class B fires (which involve flammable liquids) and Class C fires (which involve electrical hazards). Having a minimum rating of 10 BC ensures that the extinguisher has sufficient capacity and effectiveness to manage potential fire risks associated with transportation and the types of materials that trucks typically carry.

Understanding the importance of fire safety equipment and its appropriate ratings is crucial for ensuring the safety of personnel and equipment in mining operations and related transport activities.
