We should not use any open flames

We should not use any open flames like a kerosene stove or electric heater near the gas cylinder. Before igniting the gas, we should make sure that there is no foul smell of the leaking gas. If there is foul smell of gas, then the doors and windows should be opened at once to allow the gas to escape. The gas cylinder, rubber tubing and gas stove should then be properly checked to detect the cause of gas leakage.
