What is the maximum distance a portable fire extinguisher with a minimum 2-A:20-B:C rating must be accessible from a hot work area?

The maximum distance a portable fire extinguisher with a minimum 2-A:20-B:C rating must be accessible from a hot work area is 30 feet. This distance is specified to ensure that fire extinguishers are readily available for immediate use in the event of a fire related to hot work activities, which can include welding, cutting, or grinding. The 2-A rating indicates the extinguisher's effectiveness against ordinary combustibles, while the 20-B:C rating indicates its suitability for flammable liquids and electrical fires.

Having the extinguisher within 30 feet means workers can quickly reach it without delay, thus improving safety and minimizing the potential for fire to spread. This requirement reflects best practices for fire safety in environments where ignition sources are present, helping to protect both personnel and property.
