Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Industrial truck repair operations
						involving open flames or which may produce sparks or other sources of ignition
						shall not be performed in Class I, II and III locations, unless and until tests
						show that atmospheric concentrations of flammable or combustible vapors do not
						exceed 20 percent L.E.L. of such flammable or combustible materials and until
						precautions are taken to maintain the atmosphere at or below 20 percent L.E.L.
						Such precautions could include, but not be limited to removal of flammable
						material, provision for adequate ventilation, etc.
(b) Water mufflers shall be filled daily or
						as frequently as is necessary to prevent depletion of the supply of water below
						75 percent of the filled capacity. Vehicles with mufflers having screens or
						other parts that may become clogged shall not be operated while such screens or
						parts are clogged. Any vehicle that emits hazardous sparks or flames from the
						exhaust system shall immediately be removed from service, and not returned to
						service until the cause for the emission of such sparks and flames has been
						eliminated.
(c) Industrial trucks
						shall be kept in a clean condition free of debris, oil, and grease.
(d) Batteries on all powered trucks shall be
						disconnected during repairs to the primary electrical system unless power is
						necessary for testing and repair. On trucks equipped with systems capable of
						storing residual energy, that energy shall be safely discharged before work on
						the primary electrical system begins.
(e) All replacement parts for industrial
						trucks shall be equivalent in safety to the original parts.
(f) Those repairs to the fuel and ignition
						systems of industrial trucks which involve fire hazards shall be conducted only
						in locations designated as safe for such repairs.
(g) Industrial trucks shall not be altered so
						that the relative positions of the various parts are different from what they
						were when originally received from the manufacturer, nor shall they be altered
						either by the addition of extra parts not provided by the manufacturer or by
						the elimination of any parts, except as provided in subsection (h) of this
						Section. Additional counterweighting of fork trucks shall not be done unless
						approved by the truck manufacturer.
(h) Industrial trucks originally approved for
						the use of gasoline for fuel may be converted to liquefied petroleum gas fuel
						provided the complete conversion results in a truck which embodies the features
						specified for LP or LPG designated trucks. Such conversion equipment shall be
						approved.
