A worker was taken to Harborview Medical Center in critical condition after falling about 50 feet from a building under construction at 101 Taylor Avenue North in Seattle.
Workers on the site said the man, in his early 30s, is an iron worker with North Coast Iron Corp. and it was his first day on the job.
Worker David Widmer said the man had unclipped his safety gear when moving from one place to another on scaffolding on the top of the building.
"When he went over to the other side is when he tripped over that darned welder and when he tripped over the welder is when he let go, I guess, and he went down," said Widmer.
"It's a sad day for everybody," he said.
"This devastates people," said worker Matt Oliver. "It could have been any of us. It just really makes you open your eyes and realize how dangerous the job can be."
