Which door type is described as swinging (inward and outward)?

• A. Swinging (inward and outward)
• B. Revolving
• C. Sliding
• D. Overhead

Answer: (A)

Swinging doors are hinged doors that rotate on their hinges and can move in either direction. When a door is described as swinging inward and outward, it means the door can open toward the room or toward the corridor, depending on how the hinges are set up (single-acting versus double-acting). This distinguishes it from other types: revolving doors rotate around a central axis, sliding doors move along a track, and overhead doors lift up or roll up along the ceiling. In practice, swinging doors are common for many rooms, but their swing direction matters for egress flow and firefighter access, since it determines how people and equipment can pass through the doorway.
