What is a prohibition sign?
A prohibition sign is a safety sign used to indicate that a specific action or behaviour is not allowed. Their red circular border with a diagonal line crossing through a black pictogram makes these signs easily recognisable. Common examples include ‘No Smoking’, ‘No Entry’, or ‘Do Not Use Mobile Phones’. Prohibition signs are essential for maintaining workplace health and safety, helping prevent accidents and ensuring compliance with regulations. A prohibited sign communicates restrictions and reinforces safe practices for everyone on-site, whether displayed in offices, factories, or public areas.
