You may be required to comply with this standard if you intend to use a stationary or non-stationary engine in a fire protected area during the prohibited period.
Fire protected area means any land within a State forest, national park or other protected public land (or within 1.5km of a protected forest or national park).
Ordinarily it is illegal to use a chain saw, motor vehicle or other non-stationary engine in the open air or in contact with vegetation during the prohibited period in a fire protected area. This does not apply if certain conditions are met, including that the engine / exhaust pipe is fitted with a spark arrestor that complies with this standard.
This standard specifies requirements for the materials, design, construction and performance of spark arrestors for controlling the emission of sparks from internal combustion engines.
Please consult the responsible agency for more information and to ascertain the level of compliance (if any) that may be required by your business.
