In emergency egress requirements for sleeping rooms, the minimum net clear opening width is at least how many inches?

• A. 20 inches
• B. 30 inches
• C. 24 inches
• D. 27 inches

Answer: (A)

The key idea is the size of an emergency escape and rescue opening in sleeping rooms. The opening must be at least 20 inches wide, measured as the net clear width, to ensure someone can pass through quickly in an emergency. This width is the minimum to allow a person to fit through the opening, with other dimensional requirements (like height and overall opening area) also applying to make the opening usable. In practice, openings wider than 20 inches meet the requirement, and the sill height is typically limited (not more than about 44 inches above the floor) to keep the opening reachable.
