A spark arrestor is a screen that goes in the tailpipe of the dirt bike that keeps any sparks flying outback of the tailpipe and lighting a wildfire. Sparks are the common cause of fires in the dust collectors. If it is not stopped, then they can ignite the dust or dusty filters present in the ductwork.

Spark arresters for steam locomotives may be internal (in the form of wire mesh inside the smokebox) or external. The earliest platforms for spark arresters in the United States were steam locomotives. Wood- and coal-burning locomotives produce embers which are readily transported by the wind. One popular design was the Radley-Hunter spark arrester, which used a spiral-shaped cone to separate embers from the exhaust flow by centrifugal force.
