Final answer:
The size of the opening to an attic space with mechanical equipment depends on the type and size of the equipment, and should follow local building codes.
Step-by-step explanation:
The statement is false. The opening to an attic space that has mechanical equipment located in it should follow the guidelines set by local building codes. The specific size of the opening will depend on the type and size of the mechanical equipment being installed in the attic space.
For example, if the mechanical equipment is large and requires regular maintenance or replacement, a larger access opening may be required to allow for easy removal and installation. On the other hand, if the mechanical equipment is small and does not require frequent access, a smaller opening may be sufficient.
It's important to consult with a qualified contractor or building inspector to determine the appropriate size of the opening for the specific mechanical equipment being installed in the attic space.
