Working with lifting slings requires strict adherence to safety regulations and guidelines to prevent accidents, injuries, and damage to equipment or loads. Compliance with safety regulations is essential for maintaining a safe working environment. While specific regulations may vary by region and industry, here are some general safety regulations and best practices when working with lifting slings:
Know the Sling's Working Load Limit (WLL):
Always ensure that the lifting sling's WLL is appropriate for the load you intend to lift. The WLL should be clearly marked on the sling or provided by the manufacturer.
Inspect the Sling Before Use:
Conduct a thorough inspection of the lifting slings for signs of wear, damage, or deterioration before each use. Look for cuts, abrasions, broken fibers, or loose stitching.
Immediately remove damaged or suspect slings from service and replace them.
Use the Correct Sling for the Load:
Select the appropriate type of sling (e.g., wire rope, chain, synthetic web, round sling) based on the load's weight, shape, and sensitivity.
Ensure that the sling's configuration (single-leg, double-leg, etc.) matches the lifting requirements.
Understand Load Angles:
Be aware of the angle at which the sling will be used. The angle between the legs of the sling and the horizontal plane affects the sling's WLL.
Use angle correction factors as necessary to calculate the correct WLL for non-vertical lifts.
Rigging and Attachments:
Rig the sling properly and ensure that attachments, hooks, and hardware are compatible with the sling type and are in good condition.
Avoid sharp edges and abrasive surfaces that can damage the sling.
Use Tag Lines or Guide Ropes:
When lifting loads that require precise positioning, use tag lines or guide ropes to control the load's movement.
Ensure Proper Clearances:
Maintain adequate clearance for the load, including overhead and lateral clearances, to prevent contact with obstacles or structures.
Avoid Shock Loading:
Avoid sudden jerks or shock loading, which can exceed the sling's WLL. Apply gradual and controlled lifting forces.
Personnel Safety:
Keep all personnel at a safe distance from the load and rigging during lifting operations.
Establish clear communication signals and procedures between the crane operator, signal person, and riggers.
Environmental Factors:
Consider environmental conditions, such as wind, rain, or extreme temperatures, and their impact on lifting operations.
Take appropriate precautions to address adverse weather conditions.
Training and Certification:
Ensure that personnel involved in lifting operations are trained and certified in safe rigging and lifting practices.
Provide ongoing training and refresher courses as needed.
Record Keeping:
Maintain records of sling inspections, certifications, and usage history.
