In 2009, a fire incident in Truckee, California raised concerns regarding the ignitability and combustibility of high concentrations of antifreeze solutions that were used in sprinkler systems for more than 60 years. This incident involved a cooking oil fire in a kitchen where a sprinkler system with a high concentration of a glycerin antifreeze solution deployed and reportedly caused an explosion that resulted in a fatality as well as a serious injury.
The research covered by this presentation was undertaken to develop data and information to better understand the ability of certain glycerin and propylene glycol antifreeze solutions to effectively control a fire in a light or ordinary hazard occupancy when discharged from a standard spray sprinkler. Data generated from this research included information on the temperatures measured at the ceiling and a determination of the number of operated sprinklers during specific fire scenarios.
