Thermal decomposition incident

At approximately 9:15 p.m., in a sealant adhesive manufacturing plant, a mixer producing an epoxy adhesive overheated causing thermal decomposition. The smoke from the mixer filled most of a 3000 sq. ft. production room. The Fire alarm was pulled by an operator outside of the production room. The fire department arrived on scene and took control as Incident Command and called for a shelter-in-place of surrounding neighborhood. Initially, about a 4-block radius around plant was blocked to any traffic. By about 10:20pm, the fire department reduced the blocked off area to only the plant perimeter. A representative from the Emergency Response section responded to the scene and verified that there were no chemical release issues.
The fire department relieved pressure off the mixer and then set up additional exhaust fans to air out the production room, and after getting readings of less than 10 parts per million Carbon Monoxide the Fire Department gave the all-clear, which was about 12am. There was no explosion, no fire and no environmental release and the fire department did not use any extinguishing agents.
