OPERATING PROCEDURES
34
Operate the lift truck only in areas that have been ap-
proved for lift truck operation.
S
OSHA regulations prohibit the use of lift trucks in
areas containing hazardous concentrations of cer-
tain flammable gases or vapors.
S
OSHA regulations require operating areas to be
classified as hazardous or nonhazardous, and that
the lift trucks used in designated locations be of the
minimum type specified (see Guide For Users Of
Industrial Trucks, Appendix C and Table N--1).
Only the designated types of approved lift trucks may
be used in areas classified as hazardous by the au-
thority having jurisdiction. Areas classified as haz-
ardous must be identified by signs to show the type
of approved lift truck required for operation in the
area. Modifications or poor maintenance can result in
the lift truck being unsuitable for operation in areas
classified as hazardous.
The fork lift truck is designed to pick up and move materi-
als. The basic lift truck has a lift mechanism and forks on
the front to engage the load. The lift mechanism lifts the
load so that it can be moved and stacked.
In order to understand how the fork lift truck can pick up a
load, you must first know some basic things about the lift
truck.
The lift truck is based on the principle of two weights bal-
anced on opposite sides of a pivot (fulcrum). This is the
same principle used for a see--saw. In order for this princi-
ple to work for a lift truck, the load on the forks must be
balanced by the weight of the lift truck. The location of the
center of gravity of both the truck and the load is also a
factor.
This basic principle is used for picking up a load. The abil-
ity of the lift truck to handle a load is discussed in terms of
center of gravity and both forward and side stability.
