Sling Inspection & Selection deserves a specific pre-task check because suspended loads, rigging failure, overload and uncontrolled movement can expose workers to high-energy struck-by hazards. For this briefing, connect the topic to the exact equipment, work area and conditions the crew will face today, and agree a clear stop-work trigger before the task begins.
Process Safety Perspective
Critical lifts over live process equipment (heat exchangers, columns, reactors during turnaround) require the lift plan to be cross-checked against the equipment layout and any exclusion zones defined by the process safety team — an uncontrolled load path over pressurized or energized equipment introduces LOPC potential independent of the lift's own mechanical risk.
Key Points
Pre-use inspection should identify cuts, abrasion, corrosion, and deformed hardware — any one of these is sufficient to reject the sling from service
Sling angle has a nonlinear effect on capacity; a narrower included angle between legs can reduce effective capacity well below the tag rating
A sling with an illegible or missing capacity tag must be treated as unrated and removed from service
Best Practices
Document a lift plan for any critical or non-routine lift, including calculated capacity margins, not just for visually large loads
Inspect slings, shackles, and rigging hardware immediately before each use, checking against the rated capacity tag
Establish and maintain a swing radius and load path exclusion zone for the full duration of the lift
Assign a qualified signal person with agreed-upon signals confirmed before the lift begins
Never permit personnel to ride a load, hook block, or rigging under any circumstance
Match sling configuration and angle to the actual load weight — reduced sling angles significantly reduce effective capacity
Training Tip: Have someone demonstrate reading a sling capacity tag and explain how angle affects the rated capacity.
Discuss with your crew: When was the documented inspection last performed on the rigging you're using today?
Scenario & Site Check
Discuss this scenario: A crew is about to start work where sling inspection & selection is relevant, but one condition in the work area has changed since the task was last performed. Ask the team what could make that change important, which control must be verified first, and who has authority to stop the job.
Field check: verify load weight, lift path, rigging condition, capacity, tag lines and exclusion-zone control.
Evidence: confirm the applicable permit, inspection, label, test result, procedure or equipment status rather than relying only on memory.
Close-out question: “What would make us stop and reassess this task today?”
Reference Point
Use the current requirement that applies to your site. A useful starting point for Cranes Slings is OSHA / NIOSH primary guidance. Company procedures, manufacturer instructions and local law may impose additional or more stringent controls.
