Mandatory signs are safety signs used to indicate a specific action or behavior that is required in a particular area. These signs are typically used in workplaces to ensure the safety of employees and visitors. Some common examples of mandatory signs include "wear protective clothing," "wash your hands," and "use ear protection."
Mandatory signs are often designed with a blue circle and white pictogram or text on a blue background. The blue color is intended to stand out and catch the eye, making the sign easy to see and read. In many countries, mandatory signs are required by law in certain workplaces to ensure compliance with health and safety regulations. It is important to ensure that these signs are clear, visible, and well-maintained to prevent accidents and injuries.
