Which of the following best describes a requirement indicated by the term "Shall"?

• A. It is optional
• B. It is discouraged
• C. It is mandatory
• D. It is recommended

Answer: (C)

The term "Shall" is commonly used in technical standards and specifications to indicate a mandatory requirement. When a document states that something "shall" be done, it implies a strict obligation to comply with that stipulation. This creates measurable expectations and enforces compliance, leaving no room for personal discretion or optional interpretation. In the context of codes and standards, the use of "shall" differentiates it clearly from other terms that suggest lesser degrees of necessity, such as "should," which indicates a recommendation, or "may," which suggests an option. Therefore, understanding that "shall" embodies a requirement that must be fulfilled is crucial for ensuring proper adherence to safety and regulatory standards in water-based systems.
