title: Brief report: hazardous materials release resulting from home production of biodiesel--Colorado, May 2006.
abstract: On May 7, 2006, a hazardous materials (HazMat) release occurred in a residential area of Colorado when a homeowner who was processing a tank of homemade biodiesel fuel forgot to turn off the tank's heating element and left for the weekend. The heating element overheated and caused a fire that burned the surrounding shed and equipment. The shed had contained >600 gallons of biodiesel and recycled restaurant cooking oil, smaller amounts of glycerin and sodium hydroxide, and 1-gallon containers of sulfuric and phosphoric acid; a mixture of these ingredients seeped into the ground during the fire. A certified HazMat team and the local fire department responded. Investigators found seven 55-gallon barrels of methanol and other hazardous materials outside the shed. No injuries or evacuations occurred. To prevent potential injuries, biodiesel should be purchased from a licensed commercial source.
