BOULDER CITY, Nev. (KTNV)  — An evacuation was underway Monday morning at a manufacturing plant in Boulder City after an explosion, a public information officer for the city confirmed.

According to Lisa LaPlante, emergency personnel were responding to 14555 S. U.S. 95, which is the site of Amorock Polymer Concrete.

Initial reports were that at least one person had minor injuries. In a later update, officials said seven people had been injured. However, Deputy Fire Chief Greg Chesser said the actual number of people injured was six.

Chesser described a "pretty impressive explosion" that caused a fire to break out at the Armorock plant.

The employee closest to the explosion was the most severely injured with "pretty severe" burns, Chesser said. Another employee was transported to the hospital to be treated for chemical burns. Three more employees had minor concussive injuries due to the explosion, he said, and another had minor, heat-related injuries.

KTNV's Ramiro Cabrera recorded drone video where an explosion occurred at a manufacturing plant in Boulder City.

As of 11:25 a.m., the fire was extinguished. Chesser said firefighters initially had to wait for a HAZMAT crew to assess the situation before they went in to "knock down" the fire.

He couldn't immediately speak to whether heat may have been a factor in causing the explosion, noting that the presence of manufacturing chemicals was delaying their immediate ability to investigate the cause.

The Occupational Safety and Health Administration was reportedly en route to conduct its own investigation.

Armorock Polymer Concrete is situated in an industrial area approximately 7 miles southeast of Boulder City along U.S. 95.
