Two window washers in Canada clung for their lives to their work platform after high winds sent it swinging through the air and crashing into a skyscraper, video of the incident shows.

The workers were cleaning the windows of the Stantec Tower in Edmonton Friday afternoon when high winds sent them careening through the air, the Edmonton Journal reported.

The work platform then crashes into the tower, shattering the windows and flinging one of the workers off the platform, the video shows.

The flung worker — who was fortunately securely tethered to the platform — dangles helplessly as the structure continues to be tossed around, the video shows.

First responders rushed to the scene and rescued both workers soon after, according to the Edmonton Journal.
