To maintain compliance with Chain Sling Certification requirements:

• Normal Service – once annually
• Severe Service – once monthly to quarterly
• Special Service – as recommended by a qualified person

Inspection intervals should never exceed one year. While written records are not required for frequent inspections, they should be maintained. For valid Chain Sling Certifications, ASME B30.9, WSTDA, and RS-1 require a written record of the most recent inspection.

To qualify for Chain Sling Certification, all chain slings—whether new, modified, or repaired—must be inspected by both:

• A trained user before use
• A competent person at least once annually, with documented results

Proper usage is essential for maintaining Chain Sling Certification and preventing workplace accidents. Always follow these best practices:

• Replace any damaged safety latches
• Determine the weight of the load before lifting—never exceed the rated capacity
• Ensure slings and fittings fit freely—never force, wedge, or hammer them into place
• Keep hands and fingers away from tensioned slings during lifts
• Make sure the load is free and not restrained before lifting
• Perform a trial lift and trial lower to ensure stability
• Balance the load to avoid overloading a single leg or causing a sling to slip
• Use padding at sharp corners to prevent link deformation and protect the load
• Ensure hooks of multi-leg slings are facing outward
• Reduce the load limit when operating in temperatures above 425°C (800°F)
• Store chain slings properly—on racks, not on the ground—in a dry, clean environment free of contaminants
