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

When safety instructions indicate that something SHOULD be done, it implies that the action is highly recommended. This terminology suggests a strong recommendation for the safety measure to be followed, as it can significantly contribute to the safety and health of individuals in the work environment. Although it is not legally binding like a mandatory directive, following these recommendations is crucial for maintaining safe practices.

In contrast, stating that something is optional would imply that there is no necessity to follow the instruction. A phrase indicating that something is mandatory would denote a legal requirement that must be adhered to, while suggesting that an action is merely a suggestion minimizes its importance and urgency. Thus, understanding that "SHOULD" in this context emphasizes the importance of the action for safety is essential for compliance and risk mitigation in the workplace.
