A west suburban office building was evacuated Wednesday morning after a ventilation system failure released a chemical into the building's pump room. There were no reported injuries.
At 7:40 a.m., a fire alarm was activated and the Lisle Woodridge Fire District was notified of an emergency in a multi-story office building at 1001 Warrenville Road in Lisle, a release from the district said.
Firefighters found a fire alarm panel indicating alarm activation in the pump room and began a search to determine the cause. They found the ventilation system had a pump failure, which created a leak of a chemical identified by personnel as bromide.
Firefighters ventilated the building and upgraded the alarm to summon HazMat personnel, who entered the building and shut down the pump equipment. Ventilation then continued until the air quality was safe, the release said.
The fire district then turned the building over to management with notifications for repairs.
