If you smell gas, extinguish any naked flames immediately, but do not turn any electrical switches on or off. Open the door and windows to let the gas disperse. Turn off the gas supply to the stove and any other gas appliances such as a gas fire, either at the tap that supplies it, or if it does not have one, at the main tap next to the meter. Usually when the lever is parallel with the pipe the gas is on, when it is at right angles to the pipe the gas is off.
If you cannot turn off the supply, or the smell continues after the gas has been turned off, ring your area's gas supplier immediately. Their 24-hour emergency service number should be listed in the phone book.
