We had an accounting department where they put a encased display in front of distribution panels, you would open the display case to access the panels, they had a card sort machine in this area, one of the young ladies had her hand pulled into the machine, the safety stop was not working, and the machine was very heavy so no one could get access to the plug, she was sceaming and bleeding , while everyone in a panic looked for the panel, Yes it is not a problem to hide a panel until someone was injured.
