It goes without saying that industrial equipment can be dangerous when it’s being used. That’s why machines are designed with safety equipment and operators wear personal protective equipment when using them.
But machinery can also present hazards when it’s not in operation. As long as energy sources such as electricity, natural gas, steam, pressurized water, and compressed air are attached to the machine, a hazard exists. Workers who maintain or repair the equipment, or who will be working in close proximity to it, need to be made aware of these hazards and recognize that steps have been taken to protect them.
