When an earthquake occurs

1. First protect yourself.

Take shelter under a table and cover your head with a cushion, magazine, etc.

2. Once the shaking stops, calmly turn off gas appliances.

Turn off gas appliances and unplug electric devices.

Do not approach flames until any major shaking has subsided.

Close as many gas taps (and the meter tap) as possible, open windows to ventilate the area and contact Tokyo Gas immediately.

4. Make sure it is safe before using the gas

If the shaking subsides and you do not smell gas, you can open the main tap and start using the gas.

If no gas comes out, this means that the gas meter safety feature has been activated. Check to see if the light is blinking and follow the reset procedure.
