Today the plant manager walked into my office and asked "Are there any 120 circuits in the ceiling?" Kind of caught me by surprise. The answer was no. He goes on to say that he had this cell phone jammer and wanted to hide it, powered, above the ceiling of the factory bathrooms.
They have a major issue with employees using their personal cell phones while on the shop floor working, and have been cracking down. Apparently many are now taking bathroom breaks to use them in private. The main problem here isn't the cell phone use, but the lack of proper management. Our supervisors are very bad at actually supervising their underlings. Employees know they don't get in trouble for breaking rules, so they do anyway.
On to the point. I kind of blew off the question, hoping he'll forget about it. But after he left I did a quick search on the FCC website, and came up with this:
I also searched articles on the subject, etc. Many seem to be normal people using them on things like public transportation and movie theaters to interrupt those around them and create a 'quiet zone' around themselves. Not so much about companies using them. I'm going to suggest that the plant manager actually contact the FCC or something on the legal issue before attempting to implement this, but I'm just curious if it is legal or not for a company to black out portions of their own building?
