Minimum Safe Approach Distance – AS/NZS
Minimum safe approach distances to energized power
lines and their associated parts must be observed while
operating the aerial platform.
Danger
The aerial platform is not electrically insulated. Death
or serious injury will result from contact with, or in-
adequate clearance from, an energized conductor.
Do not go closer than the minimum safe approach
distance as defined by national safety regulations.
AS/NZS 2550.10:2006 define minimum distances that
must be observed when working near overhead power
lines on poles and overhead power lines on towers. Refer
to the clearance requirements decals on the machine to
determine safe approach distances (refer to Figure 1).
Figure 1 – Minimum Safe Approach Distance
Platform Capacity
The maximum unrestricted rated load capacity and the
maximum number of occupants for the aerial platform are
stated on machine decals, placards, and in the machine
specifications in this manual.
Danger
The aerial platform can tip over if it becomes unsta
-
ble. Death or serious injury will result from a tip-over
accident. Do not exceed the capacity values indicated
on the machine decals, placards, and in the machine
specifications in this manual.
Manual Force
Manual force is the force applied by the occupants to
objects such as walls or other structures outside the
work platform.
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over acci
-
dent. Do not exceed the maximum allowable manual
force indicated on the machine decals, placards, and
in the machine specifications in this manual.
The maximum allowable manual force is limited to 45 lbs
(200 N) of force per occupant, with a maximum of 90 lbs
(400 N) for all occupants.
Wind Speeds
Do not add anything to the aerial platform that will increase
the wind loading such as billboards, banners, flags, etc.
Danger
The aerial platform can tip over if it becomes unsta
-
ble. Death or serious injury will result from a tip-over
accident. Do not operate the machine in wind speeds
of 28 mph (12.5 m/s) or greater.
Do not operate the aerial platform in windy conditions
with wind gusts or steady wind speeds of 28 mph (12.5
m/s) or greater. Refer to Figure 2.
Prestart Inspection
Perform a prestart inspection before each shift as de-
scribed in Chapter 8. Do not use the aerial platform on
the job unless you are trained and authorized to do so.
Work Place Inspection and Practices
Do not use the aerial platform 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.
