The minimum working platform width for a remote condensing unit on a one-story roof sloped 3 in 12 is true: it is 30 feet or more.

• A. True
• B. False
• C. Not sure
• D. N/A

Answer: (A)

The concept being tested is safe access and working space for servicing equipment installed on a roof. When a remote condensing unit sits on a one-story roof with a slope of 3 in 12, you must provide a working platform wide enough to move around the unit, open panels, carry tools, and maintain fall protection without being cramped near the roof edge. The slope reduces usable space and increases the risk of loss of balance or missteps, so a larger platform is required to allow safe positioning, maneuvering, and access to all sides of the unit during maintenance. That’s why the minimum platform width being 30 feet or more is considered correct in this context. In practice, always verify with specific code references and manufacturer guidelines, but the broader safety principle is clear: sloped-roof installations demand ample, unobstructed space for safe service work.
