In the manufacturing industry, production consists of processing, assembling, and transporting materials. In modern times, machines use large amounts of energy to absorb the burden from workers to assist in production. This result in the wide range of development in machines that we see today. And trained workers based on experience in operating the machines create more stable quality, causing the relationship between machines and production to continue and evolve into many forms today.
The European Standards (EN Standards) in force since 1993 are representative standards on machinery safety. They are technical standards enacted to ensure compliance with basic safety requirements stipulated by the Machinery Directive across Europe, and compliance with these standards is a condition for obtaining the CE marking, required since 1995 for distribution in Europe. The following sections describe the basic concepts of machinery safety.These safety concepts are currently incorporated into the safety standards of each country as standard international safety concepts.
