You’ve identified fall hazards at your non-construction site and are ready to develop a fall protection program and train your team. But then the question comes up: who can actually provide that training?

After reviewing the Occupational Safety and Health Administration (OSHA) Walking Working Surfaces standard under 29 CFR 1910 Subpart D, two requirements stand out:

1. Employees must be trained before exposure to fall hazards.
2. Training must be conducted by a qualified person.

So what does that actually mean in practice? Does a qualified person need a specific certification or degree?

In 2020, exposure to harmful substances or environments accounted for 4,830 cases of eye-related injury or illness cases that resulted in at least one day away from work.

Research estimates that eighty to eighty five percent of our perception, learning, cognition and activities are mediated through vision, (Politzer, 2008).  A team of neuroscientists from MIT has found that the human brain can process entire images that the eye sees in as little as 13 milliseconds — the first evidence of such rapid processing speed. (Trafton, 2014). An eye injury can have serious implications for employees including their ability to drive, watch a game, or effectively communicate.
