What is the critical function of a spark arrestor on landfill equipment operating near dry vegetation?

The critical function of a spark arrestor on landfill equipment operating near dry vegetation is to prevent the ignition of the dry vegetation by capturing or extinguishing hot particles (sparks) that may be emitted from the equipment's exhaust system. Internal combustion engines, particularly those running on gasoline or diesel fuel, can produce sparks in the exhaust gases due to incomplete combustion or the presence of carbon deposits. These sparks, if released into the atmosphere, can ignite dry grass, leaves, or other flammable materials, leading to a brush fire or wildfire. A spark arrestor is a device installed in the exhaust system that contains a screen or other mechanism to trap or quench these hot particles before they can be discharged. This significantly reduces the risk of fire, especially in areas with dry and easily ignitable vegetation. Regular inspection and maintenance of spark arrestors are essential to ensure they are functioning properly and effectively preventing the escape of sparks. Many regulations require the use of spark arrestors on equipment operating in fire-prone areas.
