The work order

Movie Hazard Analysis #23 treats the rooftop chase from Vertigo (1958) as a real work order.

What moved the risk

Stopping short of the edge, keeping loads off the gutter, clearing the fall area below, and requesting technical rescue drop the hang and the response one band. They stay HIGH.

FIELD NOTE

The transfer to real work. Coworker hanging at an edge? Don't reach over. Stay back, clear below, and call trained rescue.

Every hazard, control and risk number shown comes from the JHA itself; nothing is invented or rounded for effect. Inspired by Vertigo (1958): 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.
