Pre-evacuation warnings were lifted after a hazardous materials fire, according to a news release from the Colorado Springs Fire Department.

The fire was first reported at 2:54 p.m. Sunday at Microchip Technology, located at 1150 E. Cheyenne Mountain Blvd.  Firefighters determined that a cylinder containing silane gas had ignited at the chip manufacturing facility. Applying water directly to the flames could have created additional hazards, officials said.

A handful of employees were quickly evacuated from the building, officials said. No injuries were reported.

Just after 4 p.m. Sunday, the Fire Department issued a pre-evacuation warning for the area between Venetucci Boulevard and Tenderfoot Hill Street, alerting residents about the fire and advising to be ready to leave their homes if ordered.

Hazmat specialists were able to keep the fire contained and allow it to self-extinguish. At about 1:50 a.m. Monday, crews determined that the fire was out.

“After confirming conditions were safe and there was no active leak being detected, the pre-evacuation warning was lifted at 10:50 a.m. Monday,” the release stated.

Microchip laid off nearly 240 employees in March 2024 at its Colorado Springs facility. It employed more than 1,250 in 2023, according to previous Gazette reporting.
