19. Do not use visibly worn, kinked, bird-caged, undersized, or damaged wire rope. Protect
wire rope from sharp or abrasive edges of the building. Do not use wire rope that has been
exposed to fire, excessive wear, corrosive atmosphere, chemicals, passage of electric
current, or temperatures above 203° F (95° C). For additional wire rope cautions, refer to the
wire rope section in Section 3.
Welding/Electrical Cautions
20. When welding from a suspended scaffold, provide proper electrical grounding for the hoist
and ensure the platform is grounded to the structure.
21. Insulate wire rope 4 feet (1.25 m) above and below the platform. Insulate the wire rope at
the suspension point and ensure that the wire rope cannot come in contact with the structure
at any point along its length, including the tail line. Welding protection kits are available from
Spider
®
.
22. Cover the hoist with an insulating material.
23. Avoid power lines. Make sure the platform or hand tools cannot swing or be blown within a
minimum of 10 feet (3 m) of an electrical power line. Check your local codes for minimum
distances. Never, under any circumstances, rig a platform above electrical power lines.
Corrosive/Explosive Environments
24. Never operate an electric hoist in an explosive atmosphere or around explosive organic
vapors or dust.
25. Never use hoists and aluminum platforms around caustic materials, acids, or acid fumes.
Use hoist covers when corrosive materials are present. Hoist covers are available from

of rigging stability because of one or more of the following:
Insufficient counterweight or counterweights not properly secured;
Inadequate mechanical strength;
Platform becomes overloaded when it encounters an obstacle while being raised and the
suspension wire rope breaks;
