Inward swing exit doors are permitted under what occupancy condition?

• A. It must always swing outward
• B. If occupancy under 50
• C. If occupancy over 1000
• D. Determined by the fire marshal

Answer: (B)

In means of egress, the door’s swing direction is tied to how many people might be using it at once. Outward-swinging doors are the default because they help prevent people from pushing into the path of those exiting. But there’s an exception for small spaces: if the room’s occupancy is very low (fifty people or fewer), inward-swinging exit doors can be permitted. The low number of occupants means the risk of crowding at the door during evacuation is small, and saving space in tight rooms becomes practical. So, the option that allows inward swing when the occupancy is under fifty is the correct one, while larger occupancies require outward-swinging doors and the decision isn’t left solely to the fire marshal.
