Can you tell what dangerous and illegal action the worker is engaging in? The good news: The worker scaling this elevated structure is using personal fall arrest equipment. The bad news: His body harness is upside down—the D ring should be positioned at the center of his upper back, not below his behind! The Moral: It’s not enough to equip your workers with the right fall protection equipment. You also need to ensure they’re trained to use it properly on the job.
