HOUSTON, March 6 (Xinhua) -- Seven people were injured, including one in critical condition, in a massive gas fire in Harris County, U.S. state of Texas, local media reported Saturday.
The incident happened about 40 km northwest of Houston around 6 p.m. local time Friday evening.
According to authorities, a crew of CenterPoint Energy, an electric and natural gas utility company, was working near a high-pressure natural gas line when the line was hit and exploded. The Harris County Fire Marshal's Office said all the injured people are employees of CenterPoint Energy.
Officials said CenterPoint Energy is still looking for the origination of gas line which is feeding the fire. Once CenterPoint turns that line off, the fire will go out quickly. Until then, firefighters are containing the fire and protecting the surrounding area from the flames.
The fire marshal said a 150 meter perimeter was established in the area and all residents were evacuated.
The fire knocked out power and gas to surrounding homes. Power in the area was restored Saturday morning.
