In order to ensure uninterrupted operations and safety, a routine of maintenance needs to be put to place.

Maintenance of LPG systems consists of:-

  • Checking the hoses for signs of cracks or leak and if they are suitably clamped.
  • Inspecting the cylinders, tanks and piping for signs of rust, damage and leakage.
  • Examining that the grounding cable is linked to tank and in satisfactory condition.
  • Cathodic protection system of underground installation (if provided) should be tested.
  • Vaporizers should be inspected for signs of leaks, corrosion or damage. For those used in indirect heating, checking aspects like sufficient level of water and condition of electrical connections.
  • Checking the operations of items such as level control, heat input controls, valves, flame control devices, pressure controllers, etc. Safety devices such as solenoid valves and similar items should be given special attention.

The Do’s and Don’ts of Maintenance


  • Maintain all past reports.
  • Check all appliances/burners are turned off.
  • Ensure maintenance is carried out by a competent person.
  • Remove gas cylinders from plant before carrying out any welding repair.
  • Have a procedure that allows workers to report damaged or faulty equipment.
  • Use an approved “leak detection solution” when examining pipework for leaks.
  • Use approved jointing compound on pipework repair unless fittings are intrinsically gas tight.
  • Ensure that a fire extinguisher is close at hand if maintenance work involving a fire risk is undertaken.


  • Check for gas leaks with a naked flame.
  • Expose LPG cylinders to sources of heat.
  • Expose LPG cylinders to sources of heat.
  • Allow vent ducting or flues/exhausts to become blocked with debris.
  • Undertake maintenance work without wearing correct safety clothing.
  • Carry out maintenance work on plant over a pit where leaking gas can accumulate.
