What does it mean if safety instructions state that something should be done?

When safety instructions state that something should be done, it indicates that the action is recommended in order to ensure safety. The use of the word "should" generally implies that the action is advised and is intended to guide behavior toward safer practices, highlighting the importance of following such instructions to minimize risks.

This recommendation does not carry the same legal weight as a mandatory requirement, which would typically use terms like "must" or "shall." Therefore, while following the recommendation is strongly encouraged for safety, it is not strictly enforced by law or regulations in the same manner as a mandatory instruction would be. Understanding this distinction helps clarify the level of obligation associated with safety measures, emphasizing the importance of adhering to recommended practices without implying a legal obligation.
