WINTON HILLS, OH (FOX19) - A fire broke out last Wednesday night at a chemical company in Winton Hills.
It happened around 11:45 p.m. at Emery Industries on Este Avenue.
When firefighters arrived, they found a 250-gallon vessel with heavy fire from the top that was threatening a building next to it.
It was determined that the product in the tank was Dowtherm, a heat transfer fluid. It was determined that streams would be directed on the tank to cool it and a misting spray was placed on the flames to keep them from entering the building but not extinguishing them.
Once the tank was cooled down the vapors stopped escaping and the fire went out.
Dowtherm is used as the fuel to apply heat to the process they were running in that part of the plant. Company officials said that when they started the process up it built 3 times the pressure it normally does.
The relief valve opened and the product in the air reached an ignition source and ignited. Dowtherm is a low level irritant and contains components that have caused cancer in laboratory animals.
All fire fighters operating at the scene used Self-Contained Breathing Apparatus (SCBA). The leak was not large enough to cause any evacuations except for the plant workers. Loss is listed at $750,000. No firefighters or civilians were injured. The cause at this time is a chemical reaction.
