Prohibition Signs: The Red Circle and Diagonal Bar

Prohibition safety signs forbid behaviour that could cause danger. They show a black pictogram inside a red circle with a diagonal bar on a white background; the red stands out and makes the forbidden action clear to everyone. Laboratories, fire risk areas, industrial plants, hospitals, schools and shopping centres are where they are used most.

The sign should be at a suitable height for the line of sight, well lit and unobstructed. Turkish Occupational Health and Safety Law No. 6331 and the Health and Safety Signs Regulation require such signs in appropriate places wherever risks cannot be eliminated.
