One business closed for more than two hours today after a crew doing road maintenance punctured a one-inch liquid petroleum gas line in Wahiawa.

Just before 9 a.m., the crew dug into a ground and hit the gas line while working along California Avenue near Walker Avenue, fronting KFC, said Honolulu fire Capt. Carlton Yamada.

Firefighters created an isolation zone about a block in each direction to keep people from coming near the leak, and a fire hazardous materials crew monitored the air to ensure the gas did not reach its lower explosive limits, Yamada said.

Yamada said no one was evacuated, but KFC closed because it didn’t have any gas.

A Gas Company spokeswoman said the one-inch pipe was secured by 10:15 a.m. She said the pipe served only KFC, and gas was restored to the restaurant by 11:30 a.m.

No one was injured.
