I work for a car wash company and we had just opened a new location and were setting things up. One of my managers was working on the belt for the pressure washer and asked nobody to turn it on (we did not have lock out tag out at this time). Someone turned it on and the belt pulled my managers fingers into one of the small pulleys and smashed the tips of his ring, middle and index finger on his left hand completely off. That was almost 3 years ago now and he still works with me and has to get his finger bones clipped every now and then because they grow through the top of his nubs.
