What does the word "Shall" indicate when used in a procedure?

The word "shall" in a procedure indicates that the action is mandatory, meaning it is required to be followed without exception. In procedural contexts, "shall" imposes an obligation or a requirement that must be adhered to for compliance, safety, or operational effectiveness. This clear directive leaves no room for discretion or personal interpretation, establishing a standard that must be met. Utilizing "shall" ensures uniformity and accountability in the execution of procedures, especially in critical fields such as rescue operations, where following established protocols can be vital for success and safety.

In contrast, terms like "recommended," "encouraged," or "optional" denote varying degrees of flexibility and personal judgment regarding compliance, which do not convey the same level of necessity that accompanies the word "shall."
