Combustible gas leakage may induce big disaster. But it is hard to be detected by people at initial time and disaster can not be avoided.

What we should do when we hear the gas alarm sound? Below is the professional guide to follow.

1. If you hear the gas alarm sound or suspect that there is a gas leakage, you should open all windows and doors to let the gas disperse.

2. Do not switch on lighting, press door bell, exhausting fan or any kinds of electrical appliance to avoid explosion.

3. Check all the gas appliances. Extinguish any naked flames and turn off the gas control of gas supply.

4. Call the fire department immediately outside your home or premises/ apartment.
