Boulder Fire-Rescue responded to a CU campus building for the report for haze in the building.

Around 8:30 a.m. on February 12, 2025, Boulder Fire-Rescue was dispatched to a fire alarm for the report of haze in 1905 Colorado Ave on the University of Colorado (CU) campus. Upon arrival, crew entered the building, prioritized evacuation and then moved into investigation of the light haze seen on the lower levels.

Muenzinger Psychology, Porter Biosciences, and Gold Biosciences buildings were evacuated out of safety with no injuries reported. Boulder Fire-Rescue crews were unable to locate the direct cause of the haze within the building, likely attributing it to a mechanical malfunction. There was no fire located and the situation was resolved and cleared by Boulder Fire-Rescue by 11:30 a.m.

Boulder Fire-Rescue appreciates the collaborative work with CU Police Department and CU facilities as well as the assistance of Louisville Fire and Mountain View Fire Rescue aiding on scene and the support of Mountain View Fire Rescue, Boulder Rural Fire, and Lafayette Fire for ongoing coverage within the city. When Boulder Fire-Rescue implements a 2-Alarm call it means that fire apparatuses that are outside of the city are called in to assist with an incident.
