Mandatory safety signs indicates actions that must be taken, are characterized by a blue circle with a white pictogram (symbol) or text in the center. These signs prescribe specific behaviors or the use of personal protective equipment (PPE). For example, a sign showing a hand wearing gloves within a blue circle mandates the wearing of hand protection.

• White Pictogram/Text: The white symbol or text provides a clear and easily understandable instruction. Pictograms are especially helpful because they can be understood regardless of language.
• Mandate: The essential function of these signs is to enforce compliance. They are not merely warnings or suggestions; they are directives.
