It is therefore essential to determine these risks during the construction phase of the machine and to introduce suitable risk reduction measures. The Machinery Directive 2006/42/EC demands that there is no danger posed by machines. As 100 % safety is impossible to technically implement, the challenge is to reduce the risk to a tolerable level of remaining risk. The overall safety of a machine defines the state which is deemed to be free of unwarranted risks for persons or which is deemed to be danger free. The functional safety describes the fraction of the overall safety of a system that is dependent on the correct function of the safety-related systems and external devices in order to reduce the risks. 2 Sicherheitstechnikbroschuere.indd 2 09.11.2010 12:52:42 Uhr Reducing the risks associated with a machine The international standard EN ISO 12100-1 Safety of machinery Basic concepts, general principles for design provides the constructor with detailed assistance in the identification of dangers and the risks to be examined, and contains design guidelines and methods for safe construction and reduction of risks. The EN ISO 14121-1 Safety of machinery -...
