Pressure Vessel Unit
The pressure vessel unit is responsible under Labor Code sections 7620-7771 for 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).
Permits are required for air tanks, LPG propane storage tanks over 125 gallons, and high pressure boilers over 15 psig steam. Permit exceptions depend on vessel capacity and operating pressures.

sections 450-560 and
sections 750-797.
