Prestart Inspection
Perform a prestart inspection before each shift as de-
scribed in Chapter 7. 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.
The welding ground clamp must be attached to the
same structure that is being welded.
Electrical current flow can be very intense, causing
serious internal damage to some components.
Inspect the area before and during aerial platform use.
The following are some potential hazards that may be
in the work place.
• Debris
• Slopes
• Drop-offs or holes
• Bumps and floor obstructions
• Overhead obstructions
• Unauthorized persons
• High voltage conductors
• Wind and weather conditions
• Inadequate surface and support to withstand load
forces applied by the aerial platform in all operating
configurations
Before using the aerial platform in any hazardous
(classified) location, make certain it is approved and
of the type required by ANSI/NFPA 505 for use in that
particular location.
Know and understand the job site traffic-flow patterns
and obey the flagmen, road signs and signals.
While operating the aerial platform, a good safety
practice is to have qualified personnel in the immediate
work area to:
• Help in case of an emergency
• Operate emergency controls as required
• Watch for loss of control by platform operator
• Warn the operator of any obstructions or hazards
that may not be obvious to them
• Watch for soft terrain, sloping surfaces, drop-offs,
etc. where stability could be jeopardized
• Watch for bystanders and never allow anyone to be
under, or to reach through the booms while operat-
ing the aerial platform
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 chassis,


booms, or platform. Allow sufficient room and time
to stop movement to avoid contact with structures
or other hazards.
Always look in the direction of movement.
Drive with care and at speeds compatible with the
work place conditions.
Use caution when driving over rough ground, on
slopes and when turning.
Do not engage in any form of horseplay or permit
riders any place other than in the platform.
Secure all accessories, containers, tools, and other
materials in the platform to prevent them from acciden-
tally falling or being kicked off the platform. Remove all
objects that do not belong in or on the aerial platform.
Never steady the platform by positioning it against an-
other platform.
Warning
The potential for an accident increases when operat-
ing an aerial platform that is damaged or malfunc-
tioning. Death or serious injury could result from
such accidents. Do not operate the aerial platform
if it is damaged or malfunctioning.
Do not operate the aerial platform if it is damaged or not
functioning properly. Qualified maintenance personnel
must correct the problem before putting the aerial plat-
form back into service.
Operation
Use three points of support when entering or exiting
the platform. For example, use two hands and one foot
when climbing into the platform.
Never cover the platform floor grating or otherwise ob-
struct your view below. Make sure the area below the
platform is free of personnel before lowering.
Keep both feet positioned firmly on the platform floor.
Operate the controls slowly and deliberately to avoid
jerky and erratic operation.
Always stop the controls in neutral before going in
the opposite direction.
Do not dismount while the aerial platform is in motion
or jump off the platform.
Properly stow the aerial platform and secure it against
unauthorized operation at the end of each work day,
before transporting, or if it is left unattended.
