Don’t Blow Your Top! Boiler and Pressure Vessel Inspection

On a recent Safety and Loss Control Visit to a member city I was asked the question: “Who is supposed to do inspections on our air compressor, and what is the criteria for which vessels need inspecting?”

Who?
Well, I told my contact that if you have your boiler coverage through LMCIT that is a service we provide. LMCIT works with representatives from FM Global who provides this service to our members.  FM Global completes over 1000, what are known as Jurisdictional Inspections for LMCIT, each year. Certain boiler and pressure vessels require regular inspections to ensure compliance with local regulations. This includes construction, installation, and operating codes and standards. The State of MN allows insurance carriers to perform these inspections. A representative from FM Global works with each LMCIT member in the property program to review operating conditions, maintenance and operating procedures, adequacy of safety devices to protect the equipment, and repairs and/or alterations to restore equipment conditions. The result is jurisdictional equipment that is both compliant and resilient.

What’s the Criteria for Inspection? The criteria listed below will help you determine if an inspection should be taking place.
 
 
Your boiler does not have to be inspected if it is:
  1. Located on a farm, or under federal control
  2. Located in a residence purposes for not more than 5 families
  3. A hot water heating boiler with a heat input not exceeding 750,000 Btu/Hr
  4. A railroad boiler used for transportation purposes
  5. A manually fired boiler for model locomotives, tractors. Boats or antique vehicles providing the inside diameter does not exceed 12 inches, and the grate area does not exceed 2 square feet.
 
Your hot water heater does not have to be inspected if it:
  1. Has a capacity of 120 gallons or less
  2. Has a heat input of 500,000 btu/hr or less
  3. Operates at a pressure of 160 psi of less
  4. Operates at a temperature of 210 F or less
 
Your pressure vessel does not have to be inspected if:
  1. It is an air tank less than 5 cubic feet in volume (37.5 gallons) and a safety valve set at 100 psi.
  2. It is an air tank installed on a right of way railroad.
  3. It has an inside diameter of less than 6 inches, and a length not exceeding 36 inches.
  4. It is a vessel containing water at a pressure not exceeding 300psi and temperature not exceeding 210 F
  5. It has a maximum working pressure of 15 psi.
  6. It contains liquefied petroleum gasses, or located in a petroleum refinery
  7. It is an air tank installed on a passenger bus, truck or trailer
  8. Is located on a farm
  9. It is a laundry or dry cleaning presser under 5 cubic feet (37.5 gallons)

All information for pressure, volume, and capacity will be located on the nameplate of the object.

If your boiler, hot water heater, or pressure vessel is not excluded, and should be getting inspected, please contact: DLI.Boiler.ETrakit@state.mn.us or your LMCIT Underwriter.
