You can have 1 column in a warehouse and 1forklift in the same warehouse and some fool will hit it. the forklift hits the column or the column hits the forklift. This goes back to operator attitude about safety. Most unions I have been around have supported safety issues brought up if the operators just do not seem to get it. You can repair iron and steel a lot faster and with a lot less pain than flesh and blood. Most column accidents usually have a medical condition I call crainal rectus, other wise known as head up your axx syndrome.
