1.9 ENVIRONMENTAL HAZARDS
WARNING: Touching live powerlines may result in Death or serious injury.
1.9.1
Refer to company procedures when working in the vicinity of electrical overhead powerlines.
Consult the local power company for safe operating procedures before rigging.
1.9.2
Do use of long-handled tools when working close to electric powerlines.
1.9.3
The minimum separation between live power lines and the platform and all of its components is
3 meters.
1.9.4
Verify that there are no obstructions in the vertical travel zone of the platform. Always keep a
good look-out when raising or lowering the platform. When running into an obstruction:
immediately stop the platform and inspect the platform and obstruction for possible damage
and/or hook-up. Proceed in a safe direction to clear the obstruction.
WARNING: Take care not to overload the system or get in a slack suspension wire situation
when running into an obstacle.
1.9.5
For Temporary suspended platforms with a lifting height of over 40m and intended to be used
on locations exposed to wind speeds above 14 m/s (= 50 km/h) an adequate restraint shall be
provided.
1.9.6
Carefully follow the instructions for using and checking the Sky Lock fall arrest device in a
normal, contaminated, or freezing environment.
1.9.7
When using a hoist in or near a Marine (or corrosive/salty) environment, more frequent
inspections are required. In these applications a thorough 4-hours interval inspection of the
hoists, steel wire rope, fittings and equipment has to be executed. Make sure to replace all the
components that get degraded by corrosion or wear.
WARNING: The electric powered hoists are not rated for operating in an explosion
hazardous environment. Select an air powered hoist.
1.10 HAZARDOUS ACTIVITIES : WELDING
During welding, the electrocution hazard and the risk of the welding current passing through the
suspension steel wire ropes shall be eliminated by taking the following precautions:
1.10.1 Use an insulated thimble to attach each steel wire rope to its suspension point. Electrically
insulate the extra steel wire rope stored on the top to prevent grounding or terminate the
suspension rope at the insulated thimble.
1.10.2 Cover the steel wire rope support cable with insulating material above and below the hoist. (See
Fig. 1.1) This can be done by using a length of rubber-hose, taped in position around the cable.
Proceed as follows:
a. Above the Sky Lock brake extending upwards for approximately 1.2 meter (more if required
by local safety regulations).
b. Below the hoist, extending downward sufficiently far enough to insulate the tail line from the
platform. The portion of the tail line that hangs free below the platform must be guided and/or
retained so that it does not become grounded.
