The required opening size for equipment-access rooms measuring 36 inches by 80 inches is which of the following?

• A. 24 inches by 60 inches
• B. 30 inches by 72 inches
• C. 36 inches by 80 inches
• D. 40 inches by 90 inches

Answer: (C)

Access openings for equipment-access rooms must be large enough to move equipment in and out and to allow service access. The minimum opening should match the room’s largest practical clearance, so workers and equipment can pass through without obstruction. If the room measures 36 by 80 inches, the opening needs to be at least 36 inches wide and 80 inches high to meet that requirement. That’s why the size is 36 by 80 inches. The smaller options don’t provide the necessary clearance for movement and service, while a larger opening isn’t the minimum the question asks for.
