Industry Fundamentals and Occupational Safety
Unit 6

2. 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

3. 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

4. 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.

5. Synthetic Sling Inspection

6. 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

7. 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

8. Wire Rope Damage:

9. 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)

10. Shackle Damage:

11. 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

12. 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

13. 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

14. 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

15. 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

16. 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.
