A pressure vessel is a fired or unfired container, including cylinders, used for the storage or accumulation of any gas or liquid under pressure.
Permits are required for air tanks, liquid propane gas (LPG) storage tanks over 125 gallons, and high pressure boilers over 15 pounds per square inch gauge (psig) steam. Permits to operate must be up-to-date and posted to show your agency is in compliance and taking care of your equipment. The applicable regulations are contained in CCR, Title 8, sections 450-560 and 750-797 and California Labor Code sections 7620-7771.
The Cal/OSHA pressure vessel unit is responsible for issuing the permits and overseeing the inspection of boilers (any fired or unfired pressure vessel used to generate steam pressure by the application of heat) and tanks (any fired or unfired pressure vessel used for the storage of air pressure or liquefied petroleum gases).
Permit inspections may be performed by a Pressure Vessel Unit inspector or an inspector employed by a qualified insurance company.
