I was speaking to a group of safety professionals at a conference and since it was early December, I talked about the number of people who are injured every year from falling off stepladders while putting up their outside Christmas lights. After my talk, two safety professionals came up and quietly told me how they had both become injured in the same way. One of them admitted he had actually been standing on the ‘THIS IS NOT A STEP’ warning (how many times have you done this?). He lost his balance and fell, knocking himself unconscious. He would have frozen to death if the neighbor’s child hadn’t gone home and asked his mother why Mr. Smith was sleeping on the sidewalk.
