State Health Safety Codes and Public Resources

Codes specify that in certain locations, spark arresters

must be used on internal combustion engines that use

hydrocarbon fuels. A spark arrester is a device designed

to prevent accidental discharge of sparks or ﬂames

from the engine exhaust. Spark arresters are qualiﬁed

and rated by the United States Forest Service for this

purpose. In order to comply with local laws regarding

spark arresters, consult the engine distributor or the

local Health and Safety Administrator.

NOTICE

Decommissioning is a controlled process used to safely

retire a piece of equipment that is no longer serviceable.

If the equipment poses an unacceptable and unrepairable

safety risk due to wear or damage or is no longer cost

effective to maintain (beyond life-cycle reliability) and is to

be decommissioned (demolition and dismantlement),be

sure to follow rules below.
