A series of explosions at a Texas oil field chemical supply facility set of a three-alarm fire on Friday about 40 miles north of Houston.
According to CBS, the fire started around 4:30 p.m. at the DrillChem plant in Conroe, Texas.
Firefighters and a hazardous material team responded to the blaze.
Emergency crews spent about two hours bringing the fire under control and allowed the fire to burn itself out due to threat of hazardous materials or chemicals.
“Sometimes the best plan of attack may be not any attack at all. They don’t want to do anything to endanger firefighters,” Montgomery County Fire Marshal Jimmy Williams told CBS affiliate KHOU.
There were no personnel on site when the fire erupted and no injuries were reported.
No evacuations were ordered.
Authorities have begun investigating the incident but have not yet determined the cause of the explosions.
Air monitors have been set up and the U.S. Environmental Protection Agency was notified.
“The facility was empty at the time of the fire and we are thankful that no injuries have been reported We are working closely with local authorities to determine the cause of the fire and assess the extent of the damage,” DrillChem CEO Brandon Hayes told CBS.
Nearby residents reported feeling the blasts go off and shake buildings about a mile away from the site.
“The last explosion… we heard about three or four, but the last one shook the house,” local resident Wayne Patterson told The Conroe Courier.
DrillChem supplies shale inhibitors, lubricants, and sealants and is based in Conroe, Texas.
