Movie Hazard Analysis #06 · Harpoon-and-barrel scene

Jaws (1975)

The rope was the hazard, not the shark

A harpoon, a barrel, and three men on a wet deck. Take the animal out of it and this is still a serious line-handling job.

The work order

Movie Hazard Analysis #06 runs the harpoon-and-barrel scene from Jaws (1975) as if it were a real work order: five steps, hazard by hazard, controls, and initial vs. residual risk scoring.

Featured in the video

Steps 2, 3, and 4:

  1. Stage harpoon, rope, and flotation barrels on the working deck
  2. Deploy the barbed harpoon and attached barrel
  3. Track the animal while deployed barrels create drag

What moved the risk

Free-running line, a marked bight and recoil zone, and a single assigned thrower carry most of that reduction. The residual risk is still HIGH.

FIELD NOTE

The transfer to real work. Mooring lines, tow lines, and winch operations fail the same way. The load path is invisible until it isn't, and PPE does not control line force - standing position does.

Every hazard, control and risk number shown comes from the JHA itself; nothing is invented or rounded for effect. Inspired by Jaws (1975): commentary and hazard analysis of a fictional scene as depicted, with no affiliation with the film or its rights holders. The underlying JHA was generated with JHA Rapid, is AI-assisted, and must be reviewed by a qualified safety professional before use. Not a compliance document.
