Applying NFPA 58 code requirements for fire extinguishers used at propane dispensers

NFPA 582004

6.23.4.2 Each industrial plant, bulk plant, and distributing point shall be provided with at least one approved portable fire extinguisher having a minimum capacity of 18 lb (pounds) of dry chemical with a B:C rating. Where fire extinguishers have more than one letter classification, they can be considered to satisfy the requirements of each letter class.

Check the applicable codes for your operating area to determine if the authority having jurisdiction requires a fire extinguisher at propane dispenser installations. If one is required, typically the requirement is met with a 20 pound dry chemical extinguisher with a B:C or A:B:C rating.
