Chapter 3 – Safety
Knowledge of the information in this manual, and proper
training, provide a basis for safely operating the material
lift. Know the location of all controls and how they operate
to act quickly and responsibly in an emergency.
Safety devices reduce the likelihood of an accident.
y
Never disable, modify, or ignore any safety device.
y
Safety alerts in this manual indicate situations where
accidents may occur.
If any malfunction, hazard or potentially unsafe condition
relating to capacity, intended use, or safe operation is sus-
pected, stop aerial platform operation and seek assistance.
The operator bears ultimate responsibility for following
all manufacturer’s instructions and warnings, regulations
and safety rules of their employer and/or any state or
federal law.
Failure to follow all safety rules in this manual and at-
tached to the material lift may result in serious injury or
death.
Proper training is strongly recommended before attempt-
ing to operate any mechanical device.
Prior to operation:
y
Read, understand and obey all safety rules and instruc-
tions in this manual and attached to the material lift
y
Obtain, read and obey all applicable government
regulations
y
Become familiar with the proper operation of the
material lift
y
Inexperienced users should receive instruction before
attempting to operate the material lift
Electrocution Hazards
The material lift is made of metal components and is not
insulated. Regard all conductors as energized.
Minimum Safe Approach Distance
Minimum safe approach distances to energized power
lines and their associated parts must be observed while
operating the material lift.
Danger
The material lift is not electrically insulated. Death or
serious injury will result from contact with, or inade-
quate clearance from, an energized conductor. Do not
go closer than the minimum safe approach distance
as defined by ANSI.
ANSI publications define minimum distances that must
be observed when working near bus bars and energized
power lines. Table 1 is reprinted courtesy of Scaffold
Industry Association.
Table 1 – Minimum Safe Approach Distance
Prestart Inspection
Perform a prestart inspection before each shift as de-
scribed in Chapter 4. Do not use the material lift on the
job unless you are trained and authorized to do so.
Work Place Inspection and Practices
Do not use the material lift as a ground connection when
welding.
y
The welding ground clamp must be attached to the
same structure that is being welded.
y
Electrical current flow can be very intense, causing
serious internal damage to some components.
Inspect the area before and during material lift use. The
following are some potential hazards that may be in the
work place:
y
Drop-offs
y
Holes
y
Debris
y
Uneven or unstable surfaces
y
Surfaces that will not support the forces imposed by
the material lift, its operation and its load.
y
Slippery surfaces
y
Slopes
y
Overhead obstructions
y
Power lines or other electrical conductors
y
High winds or inclement weather
y
Moving vehicles
Danger
Pinch points may exist between moving components.
Death or serious injury will result from becoming
trapped between components, buildings, structures,
or other obstacles. Make sure there is sufficient clear -
ance around the machine before moving the machine,
mast or load. Allow sufficient room and time to stop
movement to avoid contact with structures or other
hazards.
