What is the required clear width of each door used as a means of egress?

32 inches
36 inches
30 inches
28 inches

The correct answer is: 32 inches

The correct answer is 32 inches, which is the minimum required clear width for doors used as a means of egress, as specified by building codes. This requirement is established to ensure that individuals can exit a building safely and efficiently in case of an emergency. A clear width of 32 inches allows enough space for people to move through without obstruction, accommodating the needs of individuals who may be accessing the exit in a hurry or those who may be using mobility aids. In retail and commercial buildings, where large numbers of people may concurrently use exits, having an adequate door width is crucial. Wider doors enhance accessibility and reduce the risk of bottlenecks during an evacuation. Furthermore, this specification is part of the broader safety standards aimed at improving evacuation protocols and ensuring compliance with health and safety regulations in building design.
