Mandatory signs are designed to prescribe specific behaviors to ensure safety and compliance in various environments. Characteristically blue, these signs feature a white safety symbol against a blue background, clearly indicating the required actions to be taken.

Key Features:

• Behavior Prescription: Mandatory signs explicitly instruct the necessary actions to be followed, such as wearing personal protective equipment or using designated pathways.
• Distinctive Design: The blue background with a white symbol ensures high visibility and immediate recognition.
• Common Misconception: Unlike popular belief, mandatory signs are not exclusively those required by law. Instead, their use is dictated by the specific situation and the type of risk being addressed.

Mandatory signs are crucial for maintaining a safe environment, guiding individuals to act appropriately in various scenarios, and ensuring that both legal obligations and common-sense precautions are met.
