For a stormwater manhole with a 42-inch diameter, the access opening must be at least how wide?

Explanation:
A stormwater manhole must have an access opening wide enough for safe entry and maintenance work. The minimum width required is 24 inches, which allows a worker to fit through and provide room to maneuver tools and equipment inside the manhole. An opening of 18 inches would be too small for comfortable entry and for handling gear, while 12 inches is far too restrictive. A 30-inch opening would meet the requirement, but the question asks for the minimum, which is 24 inches or more.
