A mandatory sign is a visual communication tool used to convey specific actions or behaviors that must be followed in a particular setting, such as a workplace, public space, or industrial area. These signs are designed to promote safety, prevent accidents, and ensure compliance with relevant regulations.

Mandatory signs are an important part of health and safety management. They help to ensure that people are aware of the hazards in a particular area and that they take the necessary precautions to protect themselves and others.
