Industry Fundamentals and Occupational Safety Unit 6 Rigging Safety Industry Fundamentals and Occupational Safety Unit 6

Basic Safety Follow the recommended procedure Know all the aspects of your job: Tools/Equipment Tasks that needs to be completed and how to complete tasks accurately Make sure those operating the rig are certified Know proper communication

Basic Safety Take care of the equipment; the better it runs the safer it will be to work with Properly store tools Look out for others Use the proper communication Inspect equipment before use

Synthetic Sling Inspection Slings must be inspected before each use, visually and physically, for any rejection criteria. Rejection Criteria includes but is not limited to: Missing identification tag Cut severing the outer layer exposing the loadbearing yarn A knot that cannot be removed A puncture Loss of flexibility for any reason Other criteria for rejection includes: heat damage, UV damage,chemical damage, overload damage which resulted from over stretching, or a snag in the sling reveling warming yarn.

Synthetic Sling Inspection

Alloy Steel Chain Inspection Alloy Steel chains must be inspected before use, physically and visually. Rejection Criteria includes but not limited to: Missing identification tag Heat damage Excessive wear Any damage or change in links: Stretching Broken loop Twisting Rust Chipping Bending

Wire Rope Sling Inspection: Wire rope slings must be physically and visually inspected before each use. If there is any damage the sling needs to be immediately removed from use. Rejection Criteria includes but is not limited to: Broken Wires Kinking Bird Caging Rust Heat Damage

Wire Rope Damage:

Shackle Inspection: Shackles must be inspected before each use; if any damage is found the shackle should not be used for the lift. Rejection Criteria includes but is not limited to: Cracks or damage to the body of the shackle Wrong pin for the shackle Broken, loose or bent pin Missing correct markings (capacity and size)

Shackle Damage:

Eyebolt Inspection: Eyebolts must be visually inspected before each use and inspected by a qualified rigging inspector at least once a year. Rejection criteria includes but is not limited to: Scraping or abrasion Stress cracks Rust Bent Any deformation

Lifting Clamp Inspection: Lifting clamps need to be inspected before each use to check for any damage that can affect the safety of the load. Rejection Criteria Includes but is not limited to: Cracks General wear and tear Loose screws Rust

Rigging Hook Inspection: Rigging hooks should be inspected, along with the rest of the sling, before each use for damage that makes the hook no longer safe to use. Rejection Criteria includes but is not limited to: 5% increase of hook length 10% degree change from the unbent plane of hook 15% increase in opening of hook Cuts or gouges Rust

Hoist Safety/Sling Stress Keep chains and ropes clean Always perform lifts with supervision Always use appropriate protective gear Sling Stress: As the angle of the sling decreases the stress on the sling increases *90 degrees (straight up and down) will have the least amount of stress

Risk Management Risk management is when the area that the lift is occurring is analyzed before the lift begins. Risk management planning can reduce the danger of the work site Tips: Check locations of any structure in the work area to make sure it won’t obstruct the lift while the rig is moving Check for pedestrian traffic; rope or tape off the area for safety Check the weather, especially for wind and fog

Load Safety Keep the swing path of both front and back of the rig clear. Do NOT manhandle the load into position. Never stand under load being hoisted. Never attempt to slow load that is spinning too much; let it slow naturally before attempting to place it on the ground. If you are signaling make sure the rigger can see you at all times; if you are the rigger do not move the load until you can see the signaler.
