Background
 The

previous OSHA standards, while
requiring operator training, did not define
the type of training or authorization
required.
 March 15, 1988 - Industrial Truck
Association (ITA) petitioned OSHA for
specific training requirements.
33

Background (continued)
 American

National Standards Institute
(ANSI), in cooperation with ASME, has
revised its standard 4 times, including
current lifttruck technology and specific
training topics.

34

Background (continued)
 OSHA published

a proposed ruling on March
14, 1995 for General Industry, Shipyard,
Marine Terminals, and Longshoring
regulations, adding specific training
requirements.
 On January 30, 1996, OSHA proposed a
revision of the construction standards,
mandating the development of an operator
training program based on the prior
knowledge and skills of the trainee and
requiring a periodic evaluation.
35

Final Rule
 OSHA published

the final rule for
Powered Industrial Truck Operator
Training on December 1, 1998.
 The effective date is March 1, 1999. Startup dates are included in paragraph (l)(7).
 It applies to all industries except
agricultural operations.
 OSHA estimates that the new rule will
prevent 11 deaths and 9,422 injuries per
year.

Notes:
1. When the vehicle is loaded, the combined center of gravity (CG) shifts toward line B-C.
Theoretically the maximum load will result in the CG at the line B-C. In actual practice, the
combined CG should never be at line B-C.
2. The addition of additional counterweight will cause the truck CG to shift toward point A and
55
result in a truck that is less stable laterally.

 Four

major areas of concern must be
addressed:
– The general hazards that apply to the
operation of all or most powered industrial
trucks;
– The hazards associated with the operation of
particular types of trucks;
– The hazards of workplaces generally; and,
– The hazards of the particular workplace where
57
the vehicle operates.
