Is it true that net clear opening dimensions must allow for the normal operation of the opening?

Net clear opening dimensions are crucial in ensuring that openings such as doors, windows, and other access points function properly for both safety and usability. When an opening is designed, it must provide adequate space for individuals to pass through comfortably and to allow for the normal operation of mechanisms such as doors or gates. This means that any obstructions or restrictions that could hinder the normal use of the opening must be taken into account.

Design codes and standards specify minimum dimensions to ensure that openings can accommodate both people and equipment, while also considering accessibility requirements. For instance, in commercial buildings, net clear opening sizes must comply with regulations like the Americans with Disabilities Act (ADA), which mandates sufficient space for persons with disabilities to navigate through those openings without difficulty.

In summary, the statement is true because ensuring that net clear opening dimensions allow for normal operation is essential for safety, compliance with legal requirements, and ease of use.
