Safe Lifting Practices

Toolbox Talk:

Hooks Must Be Free of Defects

June 22, 2025

Hooks are one of the most stressed components in any lift. They carry the direct load connection and are subject to repeated stress, shock loading, and side pulls. A compromised hook won’t always show obvious signs of failure — but once it fails, there’s no warning. That’s why close inspection is non-negotiable before every shift.

Key Points:

  • Check for throat opening deformation. If the hook opening is stretched even slightly beyond the manufacturer’s spec, it’s out of service.
  • Inspect for cracks and nicks. Pay close attention to the saddle and eye — cracks in these areas are especially dangerous.
  • Check the latch. The latch spring must be functional and snap closed. Never bypass a damaged latch with tape or wire.
  • No twisted or bent hooks. Any bending or twisting means it’s been overloaded or side-loaded — tag it out immediately.
  • Verify markings. All hooks must be marked with their working load limit (WLL) and manufacturer ID.

If a hook isn’t perfect, it’s a liability. Replace it.

Ask the Crew:

  • Did we inspect every hook before the first lift today?
  • Are any hooks showing signs of wear, bending, or latch failure?
  • Do we know the criteria for taking a hook out of service?
