Which statement is true about fire extinguishers in propane storage areas?

• A. They May Be Used on Combustible Fires
• B. Electrical Fires
• C. Gas Leaks
• D. Chemical Spills

Answer: (B)

In propane storage areas, the fires you’re most likely to encounter involve electrical equipment—pumps, motors, control panels, etc. Because of that, the extinguishers kept there should be rated for electrical fires (Class C) or be ABC extinguishers that include electrical-fire capability. Using water on energized equipment is dangerous, since water conducts electricity and can cause shock or spread the fire. Gas leaks themselves aren’t extinguished with standard extinguishers; the priority is to shut off the propane supply, evacuate if needed, and call for help. So, the statement that fire extinguishers in propane storage areas are for electrical fires is the best fit.
