Detecting and Responding to Gas Leaks

While hazardous gas leaks are extremely rare, they can occur. If you suspect a gas leak inside your home or business and you cannot shut off the gas, immediately evacuate the area and contact 911 and HAWAI'I GAS.

Here are some safety tips if you recognize leaking gas:

  1. Immediately put out all smoking materials and other open flames. Turn off machinery and engines and avoid using cell phones or electrical switches in the area.
  2. If you are able to, safely turn off the gas. If the leak is inside an enclosed structure, ventilate the area by opening windows.
  3. If outside and the leak is underground, do not fill the hole with water. If there is a gas fire, do not try to extinguish it unless you are able to shut off the source of the gas.
  4. Immediately leave the area and warn others to stay away.
  5. Call the HAWAI'I GAS office nearest you.
  6. If the situation warrants, call 911 or your local fire department.
  7. Do not attempt to turn the gas back on by yourself. Contact HAWAI'I GAS to have a trained, qualified gas company professional restore your service.

Call 811 Before You Dig

Always make sure that there are no gas pipelines underground of where you plan to dig. Digging or running heavy equipment can damage gas lines. Even for minor excavations, such as installing a mailbox, sprinkler system, fence, or hedge, you should check before digging.

Contact the Hawai'i One Call Center at 811 (toll free) at least five workdays before you dig and provide them with the following information:

  • Your property Tax Map Key (TMK)
  • The address and location of the nearest cross street(s) near where you plan to dig
