Tips

  • The gas is basically odorless, but we impart an odor to it so that anyone can detect a gas leak quickly.
  • The city gas supplied by Tokyo Gas is lighter than air, so gas leaked indoors is suspended near the ceiling.
    One type (called 6A) of city gas and propane gas are heavier than air, so they stay near the floor.
  • Natural gas, a component of city gas, includes no harmful substances such as carbon monoxide. Therefore, if you inhale it, you will not suffer from carbon monoxide poisoning. However, such poisoning may occur when the air for combustion is insufficient during the use of a gas device or when the gas type is not compatible with the gas device.
  • Do not emit the gas without ignition, or explosion or fire may result.
