According to the Fairfax County Fire and Rescue Department "everyone went home safe," following the Dec. 4 rescue mission

Two window washers are safe after they were rescued from a malfunctioning scaffolding in Virginia on Thursday.

The Fairfax County Fire and Rescue Department (FCFRD) was dispatched at approximately 9:17 a.m., local time on Thursday, Dec. 4, to the 7900 block of Tysons One Place in Tysons, Va., regarding a "high-angle emergency" in which two people were suspended above the ground from a malfunctioning window-washing basket, according to social media updates from the department.

Technical Rescue units met with building management, who explained that the scaffold suffered a mechanical failure, leaving the two window washers stranded roughly 15 stories above the ground, the department shared.

The workers were attempting to clean the windows of Tysons Tower, according to Northern Virginia Magazine. The tower stands 22 stories tall and is home to financial, consulting, and technology firms, per its website.

Rescue crews quickly made their way to the roof of the building, where they analyzed the situation, "evaluated anchor options for rope systems, surveyed potential edge hazards, assessed wind conditions, and attempted to determine the stability of the compromised scaffold," said the FCFRD.

Upon arrival, rescue crews constructed "twin-tension rope-lowering systems" that were anchored to the building's steel beams, FCFRD said.

The first rescue was made at around 10:07 a.m., FFXNow reported, citing scanner traffic.

The FCFRD said that the rescuer performed a controlled transition over the edge and descended to the worker. After reaching the worker, they assessed the safety of their harness.
