Suspension ropes on suspended scaffolds shall meet the requirements of Section 3314.11.1 through 3314.11.8.
3314.11.1 Wraps of Rope
When winding drum hoists are used on a suspended scaffold, they shall contain not fewer than four wraps of the suspension rope at the lowest point of scaffold travel. When other types of hoists are used, the suspension ropes shall be long enough to allow the scaffold to be lowered to the level below without the rope end passing through the hoist, or the rope end shall be configured or provided with means to prevent the end from passing through the hoist.
3314.11.2 Repaired Rope
The use of repaired wire rope as suspension rope is prohibited.
3314.11.3 Rope Replacement
Ropes shall be replaced or removed if any of the following conditions exist, and as otherwise prescribed by rule of the department:
  1. Any physical damage that impairs the function and strength of the rope.
  2. Presence of kinks that might impair the tracking or wrapping of the rope around the drums or sheaves.
  3. Presence of abrasion, corrosion, scrubbing, flattening or peening causing the loss of more than one-third of the original diameter of the outside wires.
  4. Heat damage caused by a torch or any damage caused by contact with electrical wires.
  5. Evidence that the secondary brake has been activated during an overspeed condition and has engaged the suspension rope.
3314.11.4 Shielding
Suspension ropes shall be shielded from heat-producing processes.
3314.11.5 Corrosive Substances
When acids or other corrosive substances are used on a scaffold, the ropes shall be shielded, treated to protect against corrosive substances, or made of a material that will not be damaged by the corrosive substance being used.
3314.11.6 Suspended Scaffold Welding Precautions for Arcing Prevention
Precautions shall be taken to prevent the possibility of arcing through the suspension wire rope during welding operations.
3314.11.6.1 Insulated Thimble
An insulated thimble shall be used to attach each suspension wire rope to its hanging support. Excessive suspension wire rope and any additional independent lines from grounding shall be insulated.
3314.11.6.2 Insulating Material
The suspension wire rope shall be covered with insulating material extending at least 4 feet (1219 mm) above the hoist. If there is a tail line below the hoist, it shall be insulated to prevent contact with the platform. The portion of the tail line that hangs free below the scaffold shall be guided or retained or both so that it does not become grounded.
3314.11.6.3 Protective Covers
Each hoist shall be covered with insulated protective covers.
3314.11.6.4 Grounding Conductor
In addition to a work lead attachment required by the welding process, a grounding conductor shall be connected from the scaffold to the structure. The size of the connector shall be at least the size of the welding process work lead, and this conductor shall not be in series with the welding process or the work piece.
3314.11.6.5 Disconnected Grounding Lead
If the scaffold grounding lead is disconnected at any time, the welding machine shall be shut off or the welding lead shall be removed from the scaffold.
3314.11.6.6 Welding Rod or Lead
An active welding rod or uninsulated welding lead shall not be allowed to make contact with the scaffold or its suspension system.
3314.11.7 Wire Rope Clips
Wire rope clips used on suspended scaffolds shall be in accordance with Sections 3114.11.7.1 through 3314.11.7.4.
3314.11.7.1 Minimum Number of Clips to Be Installed
Where wire clips are used on suspended scaffolds, there shall be a minimum of three wire rope clips installed a minimum of six rope diameters apart.
3314.11.7.2 Installed to Manufacturer Specifications
The clips shall be installed according to the manufacturer's specifications.
3314.11.7.3 Retightening of Clips
The clips shall be retightened to the manufacturer's specifications after initial loading. Clips shall be inspected and retightened to the manufacturer's specifications at the start of each work shift thereafter.
3314.11.7.4 U-Bolt Clips
When U-bolt clips are used, the U-bolt shall be placed over the dead end of the rope and the saddle shall be placed over the live end of the rope.
Exception: U-bolt clips shall not be used at the point of suspension.
3314.11.8 Swaged Attachments or Spliced Eyes
Swaged attachments or spliced eyes on wire suspension ropes shall not be used unless they are made by the wire rope manufacturer or a qualified person. Where swaged attachments or spliced eyes are made by a qualified person, a representative sample of the assembly shall be tested under the supervision of a licensed rigger or a registered design professional to confirm the assembly will supply the clamping force specified by the wire rope manufacturer or the manufacturer of the hardware. Swaged attachments or spliced eyes shall be provided with a tag by the wire rope manufacturer or the testing entity indicating the capacity of the assembly.
Exception: J-bolts shall be designed by a manufacturer and installed in accordance with the manufacturer's specifications.
