What is a USFS spark arrestor?
(c) A spark arrester is a device constructed of nonflammable materials specifically for the purpose of removing and retaining carbon and other flammable particles over 0.0232 of an inch in size from the exhaust flow of an internal combustion engine or which is qualified and rated by the United States Forest Service.
What qualifies as a spark arrestor?
A spark arrester (sometimes spark arrestor) is any device which prevents the emission of flammable debris from combustion sources, such as internal combustion engines, fireplaces, and wood burning stoves. Spark arresters play a critical role in the prevention of wildland fire and ignition of explosive atmospheres.
Are spark arrestors required?
Good spark arrester maintenance is essential, because poor upkeep usually results in substandard equipment performance and increased fire risk. Laws and regulations do not require that spark arresters be sold already installed. As long as the arrester is provided as part of the sale, the requirement has been met.
How do I inspect a spark arrestor?
Spark Arrester Inspection Check to see if the entire exhaust system is sound and the arrester has been maintained. Also make sure that the spark arrester is mounted securely in the qualified position. In OHV use, this is usually the horizontal position. Proceed with a thorough inspection of the entire exhaust system.
Does spark arrestor stop backfire?
Backfire flame arrestors are designed to prevent the ignition of gasoline vapors in case the engine backfires. Backfire flame arrestors must be: In good and serviceable condition.
Is it bad to remove spark arrestor?
Removing it may or may not result in improved performance. You won’t know for sure until you have given it a try. On some ATVs, you may even experience a small drop in power when you remove the spark arrestor. The reduced back pressure you get by removing it will on some systems result in decreased performance.
What are the laws on spark arresters in the US?
Laws governing spark arrester use in the United States depend on the jurisdiction. Internal combustion engines operating on USDA Forest Service and most other federally managed lands must meet the requirements of the Code of Federal Regulations 36 CFR 261.52.
Do you need a spark arrester in a forest?
Internal combustion engines operating on USDA Forest Service and most other federally managed lands must meet the requirements of the Code of Federal Regulations 36 CFR 261.52. This mandate requires the operator to have a certified and properly maintained spark arrester installed at all times.
What kind of device is a spark arrestor?
A spark arrester (sometimes spark arrestor) is any device which prevents the emission of flammable debris from combustion sources, such as internal combustion engines, fireplaces, and wood burning stoves. Screen type spark arresters use a physical mesh to prevent large particles from leaving the exhaust system.
What is the SAE standard for spark arresters?
General Purpose Spark Arrestersare tested against USDA Forest Service Standard 5100-lb or the latest revision of Society of Automotive Engineers (SAE) Recommended Practice SAE J350. Either of these documents establish the minimum performance and maintenance requirements of single-position application general purpose spark arrester.
