Current through July 13, 2024
(a) Nonpermissible diesel-powered equipment,
				  except for the special category of equipment under Sec. 75.1908(d), must be
				  equipped with the following features:
(1) An
				  engine approved under subpart E of part 7 of this title equipped with an air
				  filter sized in accordance with the engine manufacturer's recommendations, and
				  an air filter service indicator set in accordance with the engine
				  manufacturer's recommendations;
(2)
				  At least one portable multipurpose dry chemical type (ABC) fire extinguisher
				  listed or approved by a nationally recognized independent testing laboratory
				  with a 10A:60B:C or higher rating. The fire extinguisher must be located within
				  easy reach of the equipment operator and protected from damage;
(3) A fuel system specifically designed for
				  diesel fuel meeting the following requirements:
(i) A fuel tank and fuel lines that do not
				  leak;
(ii) A fuel tank that is
				  substantially constructed and protected against damage by collision;
(iii) A vent opening that maintains
				  atmospheric pressure in the fuel tank, and that is designed to prevent fuel
				  from splashing out of the vent opening;
(iv) A self-closing filler cap on the fuel
				  tank;
(v) The fuel tank, filler and
				  vent must be located so that leaks or spillage during refueling will not
				  contact hot surfaces;
(vi) Fuel
				  line piping must be either steel-wire reinforced; synthetic elastomer-covered
				  hose suitable for use with diesel fuel that has been tested and has been
				  determined to be fire-resistant by the manufacturer; or metal;
(vii) Fuel line piping must be
				  clamped;
(viii) Primary fuel lines
				  must be located so that fuel line leaks do not contact hot surfaces;
(ix) The fuel lines must be separated from
				  electrical wiring and protected from damage in ordinary use;
(x) A manual shutoff valve must be installed
				  in the fuel system as close as practicable to the tank; and
(xi) A water separator and fuel filter(s)
				  must be provided.
(4) A
				  sensor to monitor the temperature and provide a visual warning of an overheated
				  cylinder head on air-cooled engines;
(5) Guarding to protect fuel, hydraulic, and
				  electric lines when such lines pass near rotating parts or in the event of
				  shaft failure;
(6) Hydraulic tanks,
				  fillers, vents, and lines located to prevent spillage or leaks from contacting
				  hot surfaces;
(7) Reflectors or
				  warning lights mounted on the equipment which can be readily seen in all
				  directions;
(8) A means to direct
				  exhaust gas away from the equipment operator, persons on board the machine, and
				  combustible machine components;
(9)
				  A means to prevent unintentional free and uncontrolled descent of
				  personnel-elevating work platforms; and
(10) A means to prevent the spray from
				  ruptured hydraulic or lubricating oil lines from being ignited by contact with
				  engine exhaust system component surfaces.
