HANDLING GAS LEAKS

extinguish all naked flames; and

avoid using the telephone or operate any electrical switches and appliances; and

open all windows and doors wide to disperse the gas; and

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; and

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; and

let your gas supply company check all your gas installations including gas appliances, LPG cylinders, etc. for safety before you use gas again.

smoke or light a naked flame; or

use the telephone or operate any electrical switches and appliances to avoid creating sparks which may cause an explosion; or

touch any gas appliances in case you operate the ignition switch accidentally, which may result in an explosion; or

ring the doorbells and notify your neighbours for evacuation when the gas leak is serious or when the situation is uncertain; or

turn on the main switch of the gas meter again before taking all necessary steps to prevent gas from leaking again; or

use gas again before having all your gas installations including gas appliances, LPG cylinders, etc. checked for safety by your gas supply company.
