According to OSHA, what is the minimum fire extinguisher rating required for refueling trucks handling flammable materials?

• A. 10-B:C
• B. 15-B:C
• C. 20-B:C
• D. 25-B:C

Answer: (C)

The correct answer, which identifies the minimum fire extinguisher rating required for refueling trucks handling flammable materials, is based on the specific hazards associated with the operations involving flammable substances. A fire extinguisher rated 20-B:C indicates that it has been tested and verified to effectively extinguish fires involving flammable liquids (the "B" rating) and can also be used on electrical fires (the "C" rating). A rating of 20-B means the extinguisher can extinguish fires covering an area of 20 square feet of flammable liquids. This size is significant for refueling operations, where there is an increased risk of larger fire outbreaks. The demands of handling and managing flammable materials necessitate a fire extinguisher that can tackle more extensive fires than those indicated by lower ratings, ensuring that workers can respond effectively in an emergency. In contrast, the lower ratings would not provide sufficient capabilities to manage potential fire risks in such hazardous environments. Therefore, a 20-B:C rating is appropriately aligned with safety standards established by OSHA for activities involving flammable materials.
