How does “Zeichen der Sicherheit“ work?

Either you take a picture or you use predefined keywords, these are the shape, the colour or the content of the sign. Now you get a short explanation about the meaning of the sign. The simple handling – a picture using your cell phone – motivates the users to check unknown symbols but aswell to make a recheck if the meaning of a symbol is not totally sure. This procedure takes just a moment and safe work can continue. A variety of signs concerning safety at work are covered, i.e. from hand signals to traffic signs.
