I have employees who smoke, and they are only allowed to smoke in a 10,000 ft area attached to the main office. my office is 50'-75' away from the door to the area. If I can smell cigarrettes, am I in danger, or do I need to be in the smoke flume out in the warehouse?

If I have to go out there, I make sure I stand 10'-20' away from them.

Any insight here?

Best!!

Mike
