Wednesday's chemical leak at a corporate office in Lisle on Warrenville road is not deemed hazardous, according to Lisle-Woodridge Fire officials. Fire Department Bureau Chief Jim French likened the bromide in the leak to a pool chemical. 

A pump failure occurred around 8 a.m. in the building's mechanical room. The failing equipment pumps water with bromide tablets throughout the entire corporate office. The pump failure led to a leakage, which created a light smoke that triggered the buildings fire alarms shortly after 8 a.m.

Lisle firefighters and police officers responded to the leak shortly after 8 a.m. French said around 60 people were evacuated from the building. No injuries were reported and no individuals were transported to the hospital, said French. 

HAZMAT teams from Downers Grove and Naperville Fire Districts responded to the scene to assist the leak. The teams entered the building and shut down the pump which distributes the solution throughout the entire corporate office. 

The fire department then sent up a ventilator at the south-east corner of the building facing away from Warrenville Road, in addition to air-monitoring equipment. 

Officials began to leave the scene at 10 a.m. French said the building owners will be able to decide whether they want to open the building today but it should be open tomorrow at the latest. 

Two weeks prior to this incident, firefighters completed evacuation training with the occupants of this building among others along Warrenville Road.
