Rooms containing equipment requiring access shall be provided with an opening of not less than __________.

• A. 24" x 60"
• B. 30" x 72"
• C. 36" x 80"
• D. 40" x 90"

Answer: (C)

Rooms with equipment that must be serviced need an opening large enough for people and gear to pass through comfortably. A standard doorway—36 inches wide and 80 inches high—fits that need well. It gives enough room for a technician to walk through with tools or a cart and enough height to move tall equipment without snagging. Openings smaller than this can impede access and make maintenance harder or unsafe. While bigger openings are allowed, the minimum that meets the requirement is 36" by 80".
