If safety instructions indicate that something shall be done, what does this signify?

When safety instructions state that something "shall" be done, it indicates a mandatory requirement. This terminology is used in legal and safety contexts to communicate that compliance is not optional; rather, it is a strict guideline that must be followed to ensure safety and compliance with regulations. The use of "shall" typically conveys an obligation to perform a specific action, making it clear that failure to do so could result in unsafe conditions or violations of safety standards. Thus, understanding this language is crucial for adhering to safety protocols.
