OE-3 2018-03: Engineered Sling Protection

This Operating Experience Level 3 (OE-3) document is being issued to raise awareness about the damage that can occur to slings during rigging operations. Any sling can be cut or damaged due to forces between the sling, connection points, and/or load that occur at edges, corners, protrusions, and rough surfaces. Appropriate, evaluated, and engineered sling protection is the industry-wide expectation to prevent sling damage or failure during rigging activities.
