Snorkel TB120 2001 - Manual (Page 9)

1. SAFETY
1 - 2 P/N 0191914
Y Y Electrocution
The TB120 is an all-metal boom, NON-
INSULATED, aerial work-platform. Do not
operate it near ELECTRICAL conductors.
Regard all conductors as being energized.
Do not operate outside during a thunderstorm.
Y Y Tipover & Falling Hazards
Do not operate a TB120 from a position on
trucks, trailers, railway cars, floating vessels,
scaffolds, or similar equipment unless the
application is approved in writing by Snorkel.
If the platform or elevating assembly becomes
caught, snagged, or otherwise prevented from
normal motion by an adjacent structure or other
obstacles such that control reversal does not free
the platform, remove all personnel from the
platform before attempts are made to free the
platform using ground controls.
Under normal working conditions it is best not to
transfer from the platform to another structure or
vice versa, unless that is the safest way to do the
job. Each situation must be judged separately
taking the work environment into account. The
following guidelines apply:
• Where possible, place the work platform
over a roof or walking structure to do the
transfer.
• Transfer your anchorage from one structure
to another before you step across.
• Remember that you might be transferring to
structure where personal fall arrest is
required.
• Use the platform entrance, do not climb over
the rails.
All platform occupants MUST wear a fall restraint
device connected to a lanyard anchor point.
Do not exceed the unrestricted platform capacity
shown on the platform.
Do not raise the boom if the TB120 is on soft
ground. Operate the boom only on a firm surface
capable of withstanding all load forces imposed
by the aerial platform in all operating conditions.
Raise the platform only when the TB120 is on
level ground.
Do not carry loads from any point outside of the
platform.
Care shall be taken to prevent rope, electric
cords, and hoses from becoming entangled in
the aerial platform.
Maintain a firm footing on the platform floor.
Climbing on the guardrails is prohibited.
Do not use ladders, planks, or other devices to
extend or increase your work position from the
platform.
Do not jerk the controls. Move the controls slowly
and deliberately to avoid jerky and erratic
operation. Always stop the controls in the neutral,
off, position before going in the opposite
direction.
Do not use the boom for any purpose other than
to position personnel, their tools, and materials.
Do not use the TB120 as a crane, hoist, or jack.
Do not operate the TB120 in winds, or wind
gusts, of 28 mph (45 km/h) or more.
Do not add anything to the TB120 that will
increase the wind loading (billboards, banners,
flags, etc).
Y Y Crushing
Always look in the direction of travel. Avoid
overhead obstructions.
Never cover the floor grating or otherwise
obstruct your view below.
Make sure the area below the platform is free of
personnel before lowering.

and doors are in place and secure.
Be sure the guardrail system, including the gate,
