If you smell gas

* Do not operate electrical switches (do not operate fan for removing the gas from the room).
* Switch OFF the pressure regulator by turning the knob clockwise to the OFF position.
* Ensure that stove knobs are in OFF position
* Do not light a matchstick even to detect the leakage of LPG.
* Open all doors and windows
* If the smell persists, call your HP Gas distributor.
* An experienced person can detach the regulator. Fix the safety cap on the valve (it too can prevent leakage of gas).
