Hazmat Crews Respond to Explosion in Sunnyvale

Hazmat crews responded to an explosion in a building in Sunnyvale Thursday afternoon which resulted in two minor injuries.

Sunnyvale public safety officials said the two people injured in the explosion worked for Altex Technologies, which has offices in the building. The employees were doing research with "particular substances" when there was a reaction that led to the explosion, officials said.

According to the Sunnyvale police, fire and hazmat crews handled the incident that occurred in the 200 block of Sobrante around 2 p.m. The building was briefly evacuated.

According to Altex Technologies website, the company is an alternative fuels and combustion research company which develops and tests new thermal management and fuel processing.

Public safety officials said Altex deals with hazardous materials.

According to a grant request, Altex is working on a $347,933 project to develop a burner for a commercial-scale boiler that significantly reduces nitrogen and carbon dioxide emissions while maintaining energy efficiency. There are several toxic spill sites located within a quarter mile of the location.

Police units briefly blocked off the area of Sobrante. The incident did not pose a threat to the public, police said.
