DON’T

  • Operate a boiler unless it is equipped with a safety valve, with sufficient relieving capacity, set at or below the maximum allowable working pressure.

  • Ever bypass the pressure controls, low water cutout, or any other limit switch or control.

  • Ever restrict the design function of any safety valve, such as by reducing or plugging the outlet, painting, or removing it.

  • Permit unqualified personnel to operate a boiler.

  • Ever leave the boiler unattended for long periods of time.

  • Operate a boiler without an adequate source of combustion air.

  • Operate a boiler without an adequate source of combustion air.

DO

  • ·Respect the boiler. It can be dangerous!

  • Have the vessel inspected internally annually, as required by State law.

  • Report newly installed boilers to the State Office of Boiler and Pressure Vessel Safety.

  • Test safety controls and devices on a periodic basis (as recommended by CSD1).

  • Ensure boiler operators are adequately trained to assure safe and efficient operation.

  • Inspect the boiler daily for proper operation, and/or adverse conditions.

  • Maintain a log of incidents that effect boiler operation, and when safety controls and devices were tested (i.e., low water cutout, safety valve(s), combustion controller).

  • Allow only authorized (“R” stamp or proper ASME symbol holder) repair firms to make welded repairs.

  • Have you burner serviced immediately, if the burner starts with a puff or operates in an unusual manner.
