True or False? The minimum working platform width when installing a remote condensing unit on a one story roof sloped 3 in 12 is 25% or greater = 30".

The statement regarding the minimum working platform width when installing a remote condensing unit on a one-story roof sloped 3 in 12 is accurate. When working on sloped surfaces, it is essential to ensure that there is enough width for safe operations, which often means adhering to specific guidelines that indicate a required minimum platform width based on the slope of the roof.

In this case, the requirement that the minimum working platform width should be 30 inches or greater for a roof slope of 3 in 12 is established for safety reasons. It allows sufficient space for technicians to maneuver equipment and perform maintenance safely, minimizing the risk of accidents or falls. This requirement ensures not only the protection of the workers but also the integrity of the installation itself.

Considering the other options, safety rails are important for additional protection but do not negate the need for a minimum working width. Similarly, the slope of the roof has specific implications for the required platform width as outlined in industry standards, irrespective of whether the roof is flat or not. Thus, the logical conclusion is that the original statement holds true.
