Washington Administrative Code › Title 332 - Natural Resources, Board and Department of (See also Title 222) › Chapter 332-24 - Forest protection › ADMINISTRATION › Section 332-24-005 - Definitions

Current through Register Vol. 24-14, July 15, 2024
Items defined herein have reference to
				  chapter 76.04 RCW and all other
				  provisions of law relating to forest protection and have the meanings
				  indicated unless the context clearly requires otherwise.
(1) "Abatement" means the
				elimination of additional fire hazard by burning, physical removal,
				or other means.
(2)
				"Additional fire hazard" means additional fire hazard as defined in
				RCW 76.04.005.
(3) "Adze eye hoe" means a
				serviceable forest firefighting hoe with a blade width of at least
				five and three-quarters inches and a rectangular eye. The blade shall
				be sharpened, solid, and smooth. The handle shall be hung solid with
				no more than three-quarters of an inch nor less than one-eighth of an
				inch extending beyond the head, smooth, aligned, and at least
				thirty-two inches long.
(4) "Approved exhaust system" means
				a well-mounted exhaust system free from leaks and equipped with spark
				arrester(s) rated and accepted under United States Department of
				Agriculture Forest Service current standards.
(a) Turbochargers qualify as an
				approved exhaust system when all gases pass through the turbine
				wheel. The turbine must be turning at all times, and there must be no
				exhaust bypasses. A straight mechanical-driven supercharger does not
				qualify as an approved exhaust system in lieu of an approved spark
				arrester.
(b) Passenger
				vehicles and trucks may be equipped with an adequately baffled
				muffler in lieu of a spark arrester.
(c) General purpose spark arresters
				for use on equipment, vehicles, and motorcycles operating on forest
				land must meet the performance levels set forth in the Society of
				Automotive Engineers (SAE) Recommended Practice SAE J350,
				"Requirements of Single Position Application General Purpose
				Arresters." The spark arrester shall be permanently marked with the
				model number and the manufacturer's identification or trademark. When
				the inlet and outlet of an arrester are not easily identified, they
				must be marked. Arresters on mobile equipment shall not be mounted
				more than forty-five degrees from the qualified position.
(d) Portable power saws purchased
				after June 30, 1977, and used on forest land, must meet the
				performance levels set forth in the Society of Automotive Engineers
				(SAE) Recommended Practice SAE J335b, "Multi-Positioned Small Engine
				Exhaust Fire Ignition Suppression." Requirements to obtain the SAE
				J335b specifications are as follows:
(i) The spark arrester shall be
				designed to retain or destroy ninety percent of the carbon particles
				having a major diameter greater than 0.023 inches
				(0.584mm).
(ii) The
				exhaust system shall be designed so that the exposed surface
				temperature shall not exceed five hundred fifty degrees Fahrenheit
				(288 degrees Centigrade) where it may come in direct contact with
				forest fuels.
(iii) The
				exhaust system shall be designed so that the exhaust gas temperature
				shall not exceed four hundred seventy-five degrees Fahrenheit (246
				degrees Centigrade) where the exhaust flow may strike forest
				fuels.
(iv) The exhaust
				system shall be designed in such a manner that there are no pockets
				or corners where flammable material might accumulate. Pockets are
				permissible only if it can be substantiated by suitable test that
				material can be prevented from accumulating in the pockets.
(v) The exhaust system must be
				constructed of durable material and so designed that it will, with
				normal use and maintenance, provide a reasonable service life. Parts
				designed for easy replacement as a part of routine maintenance shall
				have a service life of not less than fifty hours. Cleaning of parts
				shall not be required more frequently than once for each eight hours
				of operation. The spark arrester shall be so designed that it may be
				readily inspected and cleaned.
(vi) Portable power saws will be
				deemed to be in compliance with SAE J335b requirements if they are
				certified by the United States Department of Agriculture, Forest
				Service, and the San Dimas Equipment Development Center.
(e) Portable power saws
				which were purchased prior to June 30, 1977, and which do not meet
				the Society of Automotive Engineers Standards, must meet the
				following requirements:
(i) The
				escape outlet of the spark arrester shall be at an angle of at least
				forty-five degrees from a line parallel to the bar;
(ii) The configuration of spark
				arrester shall be such that it will not collect sawdust no matter in
				what position the saw is operated;
(iii) Spark arrester shall be
				designed and made of material that will not allow shell or exhaust
				temperature to exceed eight hundred fifty degrees
				Fahrenheit;
(iv) The
				arrester shall have a screen with a maximum opening size of 0.023
				inches (0.584mm.);
(v)
				The arrester shall be capable of operating, under normal conditions,
				a minimum of eight hours before cleaning is needed;
(vi) The screen shall carry a
				manufacturer's warranty of a minimum of fifty-hour life when
				installed and maintained in accordance with the manufacturer's
				recommendation;
(vii) The
				arrester shall be of good manufacture and made so that the arrester
				housing and screen are close fitting;
(viii) The arrester shall be at
				least ninety percent efficient in the destruction, retention or
				attrition of carbon particles over 0.023 inches (0.584mm.);
(ix) Efficiency is to be measured
				as described in Power Saw Manufacturer's Association Standard, Number
				S365;
(x) Construction of
				the arrester shall permit easy removal and replacement of the screen
				for field inspection and cleaning.
(f) Multipositioned engine powered
				tools, other than power saws, used on forest land must meet the
				performance levels set forth in the Society of Automotive Engineers
				(SAE) Recommended Practice J335b, "Multi-Positioned Small Engine
				Exhaust Fire Ignition Suppression."
(g) Locomotive spark arresters for
				use on logging, private or common carrier railroads operating on or
				through forest land must meet the performance levels set forth in the
				Association of American Railroads (AAR) Recommended Practice,
				"Standard for Spark Arresters for Non-Turbo Charged Diesel Engines
				Used in Railroad Locomotives."
