What minimum passage-way width is required around a boiler?

• A. 18 inches
• B. 12 inches
• C. 24 inches
• D. 16 inches

Answer: (A)

Keeping a clear passage around a boiler is necessary to give service personnel access to the front and sides for operation, inspection, and maintenance. The minimum passage-way width is 18 inches. That space allows opening the boiler door or access panel, reaching controls, and maneuvering around the unit with tools without brushing against walls or piping. It also helps maintain a safe egress path in an emergency and reduces the risk of burns or injuries when working near hot surfaces. A narrower gap, such as 12 inches, would be impractical for routine tasks. A 16-inch gap tends to be too tight for full access, and 24 inches is larger than the minimum standard, though some installations may require more due to space constraints or local codes.
