Dangerous high winds left a worker dangling from a window-washing platform on the side of a skyscraper.
Terrifying video captured by a witness, showed the platform swinging wildly and crashing through a pane on the Stantec Tower in Edmonton, Alberta, Canada.
As the scaffolding swings back and forth, gasps can be heard as the worker slips and is left hanging by just his harness.
Firefighters managed to pull the worker to safety with a ladder truck, along with ropes and a pulley system on the ground to get the scaffolding down.
Writing on Twitter after the incident, Edmonton Fire Rescue Service praised the police and ambulance service for their support and said the afternoon had been "eventful".
A post read: "Eventful, blustery afternoon in downtown Edmonton today.
