Proper maintenance and regular inspections of pressure vessels, such as boilers and tanks, are essential for safety and compliance. The Cal/OSHA Pressure Vessel Unit is responsible for inspecting and enforcing regulations to ensure the safe operation of boilers, air tanks, and other types of pressure vessels requiring inspection in California. CIRA members can access pressure vessel inspections at no cost through the PRISM Property Program. To schedule an inspection, email Hartford Steam Boiler with the types of vessels and their locations.
