Earthquake, typhoon, etc.

First, protect yourself.

When a natural disaster such as an earthquake or typhoon occurs:

1. When an earthquake occurs, first protect yourself.

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

The gas meter will automatically shut off the gas when there is an earthquake magnitude 5 or greater.

Do not approach flames until any major shaking has subsided.

2. Once the shaking stops, calmly take action.

Turn off gas appliances.

Be sure to switch off any electric appliances you are using. Unplug heating appliances such as irons and hair dryers in particular, as these can easily cause a fire.

Even if an earthquake occurs, electricity will continue to be supplied as long as there is no abnormality in the electrical equipment.
If you should leave your home and evacuate, be sure to turn off the breaker.

3. Do not touch the switches for ventilation fans or lights.

If you smell gas, do not for any reason light a flame or touch the switches for ventilation fans or lights.

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

4. After the earthquake, typhoon, or other natural disaster has subsided, make sure it is safe before using gas or electricity.

Before using gas, check the following:

  • Does it smell like gas around the gas appliance?
  • Is there any abnormality to the gas appliance such as deformation or damage?
  • Is there any abnormality to indoor or outdoor air supply/exhaust equipment such as a chimney?
    (Check visually that there is no disconnection, dent, hole, or blockage in the air supply port.)
  • Is the gas connection properly connected?
    (Check visually that the connection has not come off.)

*If you do find an abnormality, please contact the store where you purchased the appliance, the manufacturer, or the gas company for inspection and repair as there is the risk of carbon monoxide poisoning, fire, or other accident.

*If you are using a gas appliance and your eyes begin to hurt, you feel sick, or you smell an unpleasant odor, stop using it immediately and arrange for repair.

*If an appliance is flooded due to water damage, please refrain from using it and contact the store where you purchased it, the manufacturer, or the gas company to request inspection.

Gas can be used by opening the main tap.

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.

Remain near flames in use

  • If you have to light a flame, stay near it to be able to quickly extinguish it at any time.
  • Prepare your home by storing as much water as possible in the bathtub and other places and having fire extinguishers on hand.

Close unused gas taps

  • Check to make sure that the taps for unused gas appliances are closed.
  • Check that furniture will not topple or fall.
