I have been in the construction industry for over 20 years, most of which has been spent in the commercial flooring world from installation to commercial flooring contractor and everything in between. During this time, I have personally seen nasty injuries where proper safety training and enforcement would have saved a lot of pain.
In 1998 I was a helper on a jobsite with another installer who had a bad habit of carrying a 4” razor scrapper in his back pocket, he was made fun of for it, but there was no real enforcement by the foreman or the superintendent. Eventually he had an accident and cut his wrist reaching back into his pouch, it was a major laceration that ended with him in the emergency room and unable to work for over a month. Plus, he bled all over our new flooring!
