Q

Your vessel is loading Class 1 explosives using the vessel's cranes. What style of hook or shackle are you required to use to attach the lifting sling to the runner?

🔍 Key Concepts

• Dangerous cargo handling requirements when working with Class 1 explosives • Safe rigging practices for lifting hooks and shackles • Why preventing accidental release of the sling is critical during explosive handling

💭 Think About

• Look at which option best prevents the sling from accidentally coming off the hook under shock, sway, or sudden movement. • Consider which devices are specifically designed to stay secured without relying on temporary or easily displaced means (like just wire). • Ask yourself: during explosive loading, would regulations favor an open/quick-release setup or a positively secured/locked connection?

✅ Before You Answer

• Eliminate any option that allows the sling to easily jump out of the hook under sudden load or motion. • Check which choice provides a mechanical safety feature built into the hook or shackle rather than an improvised measure. • Verify which option would most likely be acceptable under strict explosive-handling safety rules, where accidental disconnection is unacceptable.
