What is the minimum fire extinguisher rating required within 30 feet of hot work operations?

The minimum fire extinguisher rating required within 30 feet of hot work operations is 2-A:20-B:C. This rating signifies the needed capacity for handling potential fires that may occur due to hot work, such as welding, cutting, or grinding, which all pose a significant risk of igniting combustible materials.

The "2-A" part of the rating indicates the extinguisher's effectiveness against ordinary combustibles like wood and paper, while "20-B" denotes its effectiveness against flammable liquids. The "C" signifies that it is also suitable for electrical fires. This combination ensures that personnel are equipped to address a variety of fire hazards often present in environments where hot work is conducted.

Understanding this rating is crucial for safety compliance, as it ensures that adequate fire-fighting resources are available in case of an emergency, helping to minimize damage and protect lives. The specific requirements may be outlined in safety regulations and guidelines, reflecting the need for compliance during hot work operations.
