Forklift Certification
Forklift/Powered Industrial Truck Safety CD-ROM Course
OSHA Regulation 1910.178 states that all new powered industrial trucks (i.e. forklifts) acquired and used by an
employer shall meet the design and construction requirements for powered industrial trucks. Approved trucks shall
bear a label or some other identifying mark indicating approval by the testing laboratory.
Modifications and additions which affect capacity and safe operation shall not be performed by the customer or
user without manufacturers prior written approval. Capacity, operation, and maintenance instruction plates, tags,
or decals shall be changed accordingly.
If the truck is equipped with front-end attachments other than factory installed attachments, the user shall
request that the truck be marked to identify the attachments and show the approximate weight of the truck and
attachment combination at maximum elevation with load laterally centered.
The user shall see that all nameplates and markings are in place and are maintained in a legible condition.
1910.178(a)
General requirements.
1910.178(a)(1)
This section contains safety requirements relating to fire protection, design, maintenance, and use of fork
trucks, tractors, platform lift trucks, motorized hand trucks, and other specialized industrial trucks powered
by electric motors or internal combustion engines. This section does not apply to compressed air or
nonflammable compressed gas-operated industrial trucks, nor to farm vehicles, nor to vehicles intended
primarily for earth moving or over-the-road hauling.
1910.178(a)(2)
All new powered industrial trucks acquired and used by an employer shall meet the design and construction
requirements for powered industrial trucks established in the "American National Standard for Powered
Industrial Trucks, Part II, ANSI B56.1-1969", which is incorporated by reference as specified in ยง 1910.6,
except for vehicles intended primarily for earth moving or over-the-road hauling.
1910.178(a)(3)
Approved trucks shall bear a label or some other identifying mark indicating approval by the testing
laboratory. See paragraph (a)(7) of this section and paragraph 405 of "American National Standard for Powered
Industrial Trucks, Part II, ANSI B56.1-1969", which is incorporated by reference in paragraph (a)(2) of this
section and which provides that if the powered industrial truck is accepted by a nationally recognized testing
laboratory it should be so marked.
1910.178(a)(4)
Modifications and additions which affect capacity and safe operation shall not be performed by the customer or
user without manufacturers prior written approval. Capacity, operation, and maintenance instruction plates,
tags, or decals shall be changed accordingly.
1910.178(a)(5)
If the truck is equipped with front-end attachments other than factory installed attachments, the user shall
request that the truck be marked to identify the attachments and show the approximate weight of the truck and
attachment combination at maximum elevation with load laterally centered.
1910.178(a)(6)
The user shall see that all nameplates and markings are in place and are maintained in a legible condition.
1910.178(a)(7)
As used in this section, the term, "approved truck" or "approved industrial truck" means a truck that is listed
or approved for fire safety purposes for the intended use by a nationally recognized testing laboratory, using
nationally recognized testing standards. Refer to 1910.155(c)(3)(iv)(A) for definition of nationally recognized
testing laboratory.
1910.178(b)
Designations. For the purpose of this standard there are eleven different designations of industrial trucks or
tractors as follows: D, DS, DY, E, ES, EE, EX, G, GS, LP, and LPS.
1910.178(b)(1)
The D designated units are units similar to the G units except that they are diesel engine powered instead of
gasoline engine powered.
1910.178(b)(2)
The DS designated units are diesel powered units that are provided with additional safeguards to the exhaust,
fuel and electrical systems. They may be used in some locations where a D unit may not be considered suitable.
1910.178(b)(3)
The DY designated units are diesel powered units that have all the safeguards of the DS units and in addition
do not have any electrical equipment including the ignition and are equipped with temperature limitation
features.
1910.178(b)(4)
The E designated units are electrically powered units that have minimum acceptable safeguards against inherent
fire hazards.
1910.178(b)(5)
The ES designated units are electrically powered units that, in addition to all of the requirements for the E
units, are provided with additional safeguards to the electrical system to prevent emission of hazardous sparks
and to limit surface temperatures. They may be used in some locations where the use of an E unit may not be
considered suitable.
1910.178(b)(6)
The EE designated units are electrically powered units that have, in addition to all of the requirements for
the E and ES units, the electric motors and all other electrical equipment completely enclosed. In certain
locations the EE unit may be used where the use of an E and ES unit may not be considered suitable.
1910.178(b)(7)
The EX designated units are electrically powered units that differ from the E, ES, or EE units in that the
electrical fittings and equipment are so designed, constructed and assembled that the units may be used in
certain atmospheres containing flammable vapors or dusts.
1910.178(b)(8)
The G designated units are gasoline powered units having minimum acceptable safeguards against inherent fire
hazards.
1910.178(b)(9)
The GS designated units are gasoline powered units that are provided with additional safeguards to the exhaust,
fuel, and electrical systems. They may be used in some locations where the use of a G unit may not be
considered suitable.
1910.178(b)(10)
The LP designated unit is similar to the G unit except that liquefied petroleum gas is used for fuel instead of
gasoline.
1910.178(b)(11)
The LPS designated units are liquefied petroleum gas powered units that are provided with additional safeguards
to the exhaust, fuel, and electrical systems. They may be used in some locations where the use of an LP unit
may not be considered suitable.
1910.178(b)(12)
The atmosphere or location shall have been classified as to whether it is hazardous or nonhazardous prior to
the consideration of industrial trucks being used therein and the type of industrial truck required shall be as
provided in paragraph (d) of this section for such location.
