How to Handle Gas Leaks in Premises

Pungent odorants are added to town gas or liquefied petroleum gas (LPG) by gas supply companies, so that gas leaks can be detected easily by gas users. If gas users detect gas leaks, they should keep calm and ensure their own safety first.

 
Should
  • extinguish all naked flames;
  • avoid using the telephone or operate any electrical switches and appliances;
  • open all windows and doors wide to disperse the gas;
  • stop the gas flow immediately by turning off the emergency control valve upstream of the gas meter (the main switch of the gas meter) if possible; for LPG cylinders, you should disconnect the regulator of the LPG cylinder to cut off the gas supply;
  • leave the premises at once and notify your neighbours by knocking on their doors for immediate evacuation when the gas leak is serious or when the situation is uncertain; leave the building by the stairs, dial 999 to notify the Fire Services Department, and call your gas supply company for sending their emergency personnel to the scene to deal with the gas leak;
  • let your gas supply company check all your gas installations including gas appliances, LPG cylinders, etc. for safety before you use gas again.
 
 
Should Not
  • smoke or light a naked flame;
  • use the telephone or operate any electrical switches and appliances to avoid creating sparks which may cause an explosion;
  • touch any gas appliances in case you operate the ignition switch accidentally, which may result in an explosion;
  • ring the doorbells and notify your neighbours for evacuation when the gas leak is serious or when the situation is uncertain;
  • turn on the main switch of the gas meter again before taking all necessary steps to prevent gas from leaking again;
  • use gas again before having all your gas installations including gas appliances, LPG cylinders, etc. checked for safety by your gas supply company.
