Movie Hazard Analysis #17 · Rooftop rope assault

Shaft (1971)

The safest rope descent is the cancelled one

The rope descent, the window breach, the armed confrontation: the JHA cancels all of it, and that is the only thing that moves the risk.

The work order

Movie Hazard Analysis #17 treats the rooftop rope assault from Shaft (1971) as a real work order: six people, one high-rise, five steps.

What moved the risk

Cancelling before site approach, withdrawing from the perimeter, and notifying law enforcement do all of the reducing. PPE gets credit for nothing.

FIELD NOTE

The transfer to real work. The biggest risk reduction in this JHA came from one word: cancel.

Every hazard, control and risk number shown comes from the JHA itself; nothing is invented or rounded for effect. Inspired by Shaft (1971): 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.
