What are the OPD requirements under NFPA 58?
NFPA 58 requires an OPD on all cylinders with 4 to 40-pound propane capacity that are: • Fabricated (manufactured) after September 30, 1998; • Requalified after September 30, 1998; or • Refilled on or after April 1, 2002. For most consumers, the OPD requirement applies to their 20 lb gas grill tank. Exceptions: NFPA 58, 1998 Edition states the OPD requirement does not apply to cylinders used in industrial trucks, including forklifts trucks, or to cylinders identified and used for industrial welding and cutting gases. The NFPA 58, 2001 Edition broadens the provision to include certain cylinders manufactured before October 1, 1998, and designed for use in the horizontal orientation.
