DEFINITIONS 3.1 Fire Fuel Material that can burn readily, usually organic debris su

21、ch as wood particles or liquids such as oil or solids such as rubber or plastics. 3.2 Fire Risk Area A fire fuel, oxygen and an ignition source in immediate proximity to each other. 3.3 Hydraulic Fluid The ignitable form of the liquid used for hydraulic systems. (certain provisions of this document

22、do not apply to non-flammable hydraulic fluid) 3.4 Ignition Source An object providing sufficient heat energy to ignite a fire fuel. 3.5 Wiring Electrical conductors, including electrical wires, harnesses, cables and other related components such as connectors and inline fuses. 4. MACHINERY DESIGN 4

23、.1 Risk Analysis A fire risk analysis can be used to identify hazards and evaluate fire risks as part of the design process. Consideration of the fire risk is part of the product development process in which design decisions often balance conflicting objectives such as regulatory constraints, size a

24、nd space limits, productivity targets and performance capabilities. A low risk design avoids creation of hazards. Protective features can be used to reduce the risk if a hazard is unavoidable in the design. Warnings can supplement protective features and are generally necessary if protective feature

25、s cannot be provided. A fire risk analysis can be one of many tools for making design decisions. The analysis may be a part of the working process of the designer or it may be a formalized exercise using a pre-defined set of procedures. 4.2 Ignition Sources Heat energy transfers from an ignition sou

26、rce to a suitable fire fuel material to ignite a fire. If the ignition source is identified and controlled, the risk of a fire can be reduced. Common ignition sources found on machines are hot surfaces, hot particles, and electrical current. a. Isolation or shielding of the exhaust component surface

27、s of an engine can reduce the possibility of direct contact with ignitable debris or fluids. b. Shields on brake components can reduce the accumulation of ignitable material around the brake pads and surfaces. Improper shielding may trap or collect combustible materials creating a risk. c. Machine a

28、djustment ranges, component wear, and debris accumulations are factors that can lead to friction heating by moving parts. Identification and access for maintenance of exposed moving parts can reduce the risk level. SAE INTERNATIONAL J1212 Reaffirmed JAN2015 Page 5 of 8 d. Forestry machines with inte

29、rnal combustion engines are generally required by regulation, e.g. U.S. Code of Federal Regulations 1910.266(f)(6), to have an exhaust spark arresting capability. Application guidance for spark arresting devices, including full flow non-bypass turbochargers, is found in the U.S. National Wildfire Co

30、ordinating Groups Spark Arrester Guide NFES 1363. e. A circuit over-load or short can overheat wiring or electrical devices and can cause ignition of a fire fuel. Electrical arcing can ignite fire fuels or gases. Circuit breakers or fuses provide over-current protection. Wiring restraints prevent in

31、sulation wear or damage. Guarding or shielding can reduce the risk level if electrical wiring is routed through a fire risk area. f. Identification and easy access enables regular inspection and maintenance of battery and alternator cables. Battery cable end covers prevent accidental short circuits

32、and arcing. Physical protection, restraints and short routing lengths can reduce the risk level of cables that do not have over-current protection. g. A battery disconnect switch will de-energize the electrical system of a machine and prevent electrical hazards when the machine is not operating. Eas

33、y access to a clearly identified battery disconnect switch promotes regular use. Over-current protection can be used for wiring that must not be interrupted by a battery disconnect switch. 4.3 Fire Fuel Materials Fire fuel materials can be ignited by an ignition source in the presence of oxygen. The

34、 risk of a fire is reduced by keeping fire fuel materials separated from an ignition source or oxygen. a. Enclosures, shields and air circulation patterns limit the entry and accumulation of forestry debris around an engine. Minimizing the number and size of openings on an engine cover reduces the a

35、mount of debris material that can drop down onto the engine unless other provisions are made to avoid debris accumulation. b. Accumulation of fire fuel material on the machine can be reduced by avoiding pockets and ledges, including those created by hose routings, brackets, shields and other compone

36、nts. Debris accumulations in the machine under-guarding and in areas where saturation of debris with leaking fuel and oil can occur can be hazardous. Providing easy service access to material accumulation areas promotes effective and regular cleaning. c. Direct engine air intake pre-cleaner debris d

37、ischarge away from engine hot surfaces or any other ignition sources. d. SAE J930 provides installation guidance for batteries to reduce hazards associated with the accumulation of ignitable gases or vapors. e. A higher flash point engine fuel can reduce the level of fire risk. f. Fuel line routing

38、to avoid fuel spillage in the event of a fuel line rupture or leak can reduce the fire hazard. g. Qualified fuel hose systems that are capable of withstanding a 2.5 minute fire test are listed in SAE J1942 and SAE J1942/1. h. A fuel or oil system that does not leak during machine operation or does n

39、ot leak into a fire risk area if the machine is overturned and comes to rest on either side or upside down on a horizontal surface for an extended time period can reduce the level of fire risk. i. Use of combustion resistant materials for hoses, tanks and other ignitable fluid containers can reduce

40、the level of fire risk. ISO 21507 provides flammability requirements for non-metallic fuel tanks. SAE J30 and SAE J517 provide material specifications for fuel and hydraulic hoses. j. Steel tube is an alternative for hoses that must be routed through a fire risk area such as near hot engine componen

41、ts. k. A shield or cover that is not simultaneously a trap for debris can be used to contain or deflect an unexpected fluid spray or leak from fluid lines located in a fire risk area. SAE INTERNATIONAL J1212 Reaffirmed JAN2015 Page 6 of 8 l. Selecting and positioning of fuel and hydraulic components

42、 to minimize leakage or spillage during normal servicing, including fueling, can reduce the level of fire risk. m. The use of flame retardant material in the operator station can reduce the level of risk of operator injury in the event of a fire. A maximum burning rate of 4 inches / minute or 100 mm

43、 / minute is given in ISO 11850 for the burning rate when tested according to ISO 3795. 4.4 Fire Safety a. Provide fire-prevention information and instructions to the machine owner and operator as required by ISO 3600 and ISO 11850 (part 5.1). Include considerations from Section 5 of this document a

44、s appropriate for the particular machine. b. Provide instructions about general cleaning of debris and other combustible material from the machine including considerations from Section 5 of this document as appropriate for the particular machine. c. Information labels or safety warning labels can be

45、 used to provide fire safety information from Section 5 of this document. SAE J115, ISO 9244, ISO 11684-1 and ISO 11684-2 provide guidance about labeling to identify, prevent and/or avoid hazards. d. Consider the risk of operator injury in a fire event during operator egress design. e. NFPA 10 or eq

46、uivalent regulations require fitting one or more portable hand extinguishers. Mount the extinguisher(s) in a low fire risk area and select extinguisher(s) with a capacity rating appropriate for the size and type of machine, but not less than a 2A-10BC rating as defined in UL 711. Placement of one ex

47、tinguisher in a position easily accessible from the operators station enables rapid response. Other local regulations may apply. Regulatory requirements such as NFPA 10 may not be sufficient for some machines. f. Placing identified fire extinguisher deployment (access) holes adjacent to fire risk ar

48、eas that are not otherwise accessible aids fire suppression efforts. Multiple access hole locations can encourage dispersion of the extinguishing agent throughout the enclosed volume. Consider ergonomics in the placement of access holes. Access holes within reach from the ground offer advantages. g.

49、 One or more clearly identifiable emergency shutdown switches on stationary or remote controlled machines, accessible from the ground and away from fire risk areas, may aid a rapid shutdown response. 5. MACHINE OPERATION AND MAINTENANCE Effective prevention of fire in forestry machines requires that machine owners, operators and mainten
