What does "should" indicate in safety instructions?

"Should" in safety instructions indicates that a specific action is recommended. This language suggests that while following the instruction is advisable for ensuring safety, it is not legally binding or strictly necessary. The use of "should" implies that adherence to the recommendation could enhance safety or minimize risks. Therefore, individuals are encouraged to follow this guidance for their well-being, but they have the option to deviate from it based on their judgment or circumstances.

In contrast, other terms like "must" would communicate a mandatory requirement, while "may" or "can" would indicate that the action is optional. Thus, the nuance of "should" clearly aligns with the idea of a suggestion that should be taken seriously for optimal safety practices.
