Lock Out, Tag Out | Construction Safety | F.E. Moran Special Hazard Systems

Picture this scenario: A maintenance worker turns off a machine to climb inside and start working on a part. Another worker sees the machine is off, and switches it back on - not seeing the maintenance worker inside the machine. The worker is crushed, maimed, or worse as the machine activates. 

Here is a video interviewing people who knew a man who would have been saved if a lock out/tag out procedure was completed because of this exact scenario.
