A SIGN OF SAFETY. Safety signs are essential in all companies, public buildings and places where people must be protected. In industry and the public sector, there are about 800,000 reportable accidents at work each year which result in a prolonged inability to work or death. In order to prevent accidents at the workplace, use mandatory signs, prohibition signs or warning signs. Rescue and fire protection signs, on the other hand, ensure the necessary orientation for employees or the fire brigade in emergency situations due to their long-lasting luminescence. The purpose of a safety sign is, therefore, to draw attention quickly and easily to situations and objects which may pose certain risks.
