The Boiler Inspection Program enforces nationally adopted standards governing the installation, operation, maintenance and repair of boilers and some pressure vessels in commercial and public buildings. Periodic inspections are performed by State Inspectors or by special (insurance company) inspectors commissioned by the Boiler Inspection Program. Inspections are performed to verify compliance with the established safety requirements. The Boiler Inspection Program was implemented to ensure safety because boilers can explode, causing property damage, injuries and deaths.
- There are over 40,000 regulated boilers in Colorado.
- In general, there are two categories of boilers: low-pressure heating boilers and high-pressure boilers.
- Low-pressure heating boilers:
- Are either steam boilers that operate with no more than 15 psi steam pressure or hydronic (water) boilers that operate with no more than 160 psi water pressure and no more than 250°F operating temperature;
- Are commonly found in office buildings, schools and apartment buidlings providing hot water heating or hot water supply; and
- Include domestic water heaters if the heat input is 200,000 BTU/hr or greater, 210°F or greater or if the water volume is 120 gallons or greater.
- High-pressure power boilers:
- Are steam boilers that operate at steam pressures greater than 15 psi;
- Include high temperature/high pressure hydronic (water) boilers that operate at greater than 160 psi water pressure and/or 250°F; and
- Are normally used for utilities, processing plants, drill rig sites, commercial laundries, dry cleaners and hospitals.
