Introduction
The term
“safety” derives from Latin and refers to a state that is free from unacceptable risks.
This fundamental human requirement is also enshrined in basic EU law.
The safety of machines and systems mainly depends on the correct application of
standards and directives. In Europe, the basis for this is the Machinery Directive, which
provides standard specifications to support companies when designing safety-related
machines. The aim is to eliminate barriers to trade within the EU. However, even outside the
European Economic Area, many European standards are gaining in importance due to their
international status.
The fact that the safety of machines and systems not only depends on the components and
technologies used, but is mainly affected by the
“human” factor is no surprise.
