The term "shall" is used in legal and regulatory language to indicate something that is mandatory or obligatory. When a document states that something "shall" be done, it signifies that there is a requirement to carry out that action, leaving no room for discretion. This is different from terms like "should" or "may," which imply recommendations or permissions rather than requirements.

In the context of regulations, such as those from OSHA (Occupational Safety and Health Administration), the use of "shall" clearly establishes that compliance is not optional; entities must adhere to those requirements to ensure safety and health standards are met. Understanding this terminology is crucial for interpreting legal texts or compliance documents effectively.
