carries a Working Load Limit( WLL). To account for dynamic load swings, angle loading and unforeseen stresses:
• Never exceed WLL.
• Apply industry safety factors( typically 5:1 or higher depending on application).
• Use slings that are tagged and traceable to service records.

Consider Sling Angles and Load Geometry Tandemloc highlights that incorrect sling angles can cause catastrophic overloading even when lifting below rated weight. Good rigging plans model these angles before lift execution:
• As sling angle decreases( moves away from vertical), tension increases.
• Slings at 60 ° may double stress compared to vertical lifts.

Inspect
All Rigging Gear Before Use

Greenfield relates that only visual and hands-on inspections can detect worn gear. Rigging gear must be inspected before every lift to:
• Look for frays, kinks, broken wires, corrosion, deformation and heat damage.
• Check sling end fittings, hooks and attachments for cracks or wear.

Use Proper Taglines and Control Lines Mazzella points out that controlling the load during movement is critical for reducing unintended motion and to provide for precise control. Taglines are especially valuable in windy conditions or confined spaces to:
• Prevent load spin or rotation.
• Keep personnel clear of the load’ s swing path.

Communication LGH emphasizes communication as a core risk mitigation step. Best practices include:
