What is the minimum height, in inches, for roof railings near gas units?

• A. 42 inches
• B. 36 inches
• C. 48 inches
• D. 60 inches

Answer: (A)

The main idea here is fall protection for elevated work areas around gas equipment. When you’re working on a roof near gas units, the railing along the open edge must be tall enough to act as a reliable barrier. The standard minimum height for roof railings is 42 inches. This height aligns with general fall-protection practices (and is commonly adopted by NFPA 54 and OSHA-related guidelines) to prevent accidental falls while still allowing workers to maneuver and access appliances. Trying to use a shorter railing, such as 36 inches, would not meet the required protection, while taller heights like 48 or 60 inches exceed the minimum but may be used if a particular situation or authority requires it. So, the minimum acceptable height is 42 inches.
