I am working in a room where a coal belt runs. The coal belt feeds 5 or 6 coal bins below it. The coal is used to fire some industrial boilers. The coal bins are closed off to the room I am working in at the present time.
The room is rated Class II division II. At this time the area has not run in about two weeks (summer shut down). A lot of work is being done to update the controls and other systems. The room has been cleaned. There is no coal dust in the air although there is some on the floors and everywhere else. My question is this. When not running the coal belt and all the other associated equipment is this room still rated Class II Division II? We are being told by some people it is. Some of us argue, in the room?s present state, it is not. If it is still rated Class II Division II this makes drilling holes in concrete for anchors and in steal almost impossible along with a lot of other task associated with making possible sparks. We also have two roof vents (4? x 6?) open and two doors that go to the outside open. Can we use 120 volt drill and saw motors without violating the NEC and endangering anyone?s life? There is a lot of fresh air available. I would like to hear some of the other opinions out there. Thanks.
