The bar must be set up in an accessible, hazard-free location; it must be operating in compliance with the Fire Regulations and within the legal occupancy limits. As such, a bar cannot be set up in such a way as to obstruct the fire exits or the passage of persons in and out of a building/classroom. It is preferable that the bar not be situated on a stage or in the proximity of stairs or blocking a hallway. One other important requirement is that the bar be situated in a clearly defined licensed area so that only guests invited to that event are allowed to consume alcoholic beverages.
