![]() ![]() Even dry silage is too wet to burn quickly. The fuel source for a silo fire is the silage, although it typically is not a highly effective fuel source because of its moisture content.The dryer the material, the more trapped air there is. The air source for a silo fire includes air that is trapped in chopped forage during harvest and air that blows into the silo.Pyrolysis allows oxygen in the silo to support a smoldering fire that can result in charred cavities in the silage. Once the oxygen is consumed, the fermentation process begins and continues until the forage becomes stable. Microorganisms are killed at 250☏–400☏, causing a breakdown in the forage through an oxidation process called pyrolysis. This action produces heat until all the oxygen in the pile is consumed. The heat source for a silo fire is bacterial action within the silage. When forage material is cut, bacterial action on the forage begins.Three ingredients are needed for anything to burn: a heat source, air, and fuel. The approach to managing a fire, however, is based on the type of silo in which the fire is burning. Fire prevention steps are similar regardless of what type of silo you have. Retrieved from ….īecause the ingredients needed for a fire to occur are present in silos, agricultural producers who have silos should take steps to minimize the likelihood of silo fires and be prepared to manage silo fires should they occur. ![]() (2015) Farm and Ranch eXtension in Safety and Health (FReSH) Community of Practice.
