1.3.10 Safety Checklist

  • Equipment containing burners must never be towed or transported while a burner is in operation.
  • Propane cylinders must be stored and transported in an upright position at all times.
  • Protective collars must be on cylinders at all times.
  • Pressure regulators must be removed from all cylinders when not in use.
  • Never force brass or bronze fittings because you will strip the thread.
  • After changing cylinders or making new hose connections, check all unions for leaks with soapy water or leak detection liquid.
  • Never use a flame to detect possible leaks.
  • All valves must be turned on fully when the system is  in operation. The only device regulating the flow of gas should be the pressure regulator.
  • All valves must be closed when the burner is not in use.
  • Never leave gas in the lines. Always burn it off. Close valves in the following order:
  1. Shut off container valve.
  2. Shut down the pressure regulator to minimum and allow all gas to burn off.
  3. Shut off the burner valve.
  • Relief valves on cylinders must always point away from the burner.
  • Never use a burner bigger than the size recommended for the piece of equipment as it will burn out the heating tubes, deteriorate the quality of the bitumen and/or cause a fire or explosion.
  • Never light a burner while it is in the kettle or tanker.
  • Hoses must never be put into the burner well of a kettle.
  • Propane cylinders must be located at least 4.5 m (15 ft) away from burners at all times. Larger tanks and propane trailers must be located at least 7.6 m (25 ft) away from burners at all times.
  • Ensure all areas are well ventilated. Because propane gas is heavier than air, escaping gas could collect in low places and create a flammable mixture.
  • Because most propane cylinders are made of steel, they are subject to rust. Rust can lead to pitting in the cylinder exterior and render the cylinder useless if the rust or pitting is excessive. The most common place rust is found is on the bottom of the cylinder and around the foot ring of the cylinder so it is important to keep these areas clean.
