Storage / Warehouse, Warehouse Oak Ridge, TN – Warehouse fire caused by spontaneous combustion controlled by sprinkler system July 25, 2016 viking210 On Thursday, at about 6:50 am, the Oak Ridge Fire Department was dispatched to a report of a sprinkler system activation alarm. Upon arrival at 342 Warehouse Road, the Fire Department found heavy smoke coming from the windows and doors of the building. The Fire crew entered through the front door and quickly extinguished a fire in a waste container. The structure was unoccupied at the time of the fire and damage was minimal. The fire was initially controlled by the building sprinkler system; with a single sprinkler head activating. The fire was contained to a waste container and the remainder of the business suffered minimal heat and smoke damage. Without the sprinkler system, several businesses within the building could have been destroyed, an ORFD press release said. The cause of the fire appears to have been spontaneous combustion from oily rags discarded in the waste container. This fire points out two critical safety items worth discussing: Sprinkler systems save lives and property. Many folks complain about the cost of maintaining their commercial sprinkler system; however the cost is fractional to the loss of a structure, business and local jobs. This fire was another excellent example of the sprinkler system controlling the fire and notifying the fire department for additional response. This is the third fire in Oak Ridge in the past four years started by spontaneous combustion. Discarding oily rags from refinishing furniture, cleaning wood products, working on vehicles, or any other work which involves certain types of oil products can begin to create internal heat to the point where the rags ignite. The rags should be kept in a covered metal container or laid out flat so the residue can evaporate prior to being disposed of. The final solution requires either destruction by something like burning, or a safe way to let the material cure without cumulating heat. For home and small commercial shops, the easiest way is to spread the rags in a single layer so heat dissipates while the material cures. Then, depending on local regulations, the materials can be safely disposed of, either in hazardous waste collection sites, or in the general landfill, the press release said.
