The objective of safety systems is to keep potential hazards for both people and
the environment as low as possible by using suitable technical equipment, with-
out restricting, more than absolutely necessary, industrial production, the use of
machines and the production of chemical products. The protection of man and
environment has to be put on an equal footing in all countries by applying rules
and regulations that have been internationally harmonized. At the same time,
this is also intended to avoid that safety requirements in different countries have
an impact on the competitive situation, i.e. the intention is to facilitate interna-
tional trade.
Legislation demands, "the quality of the environment and the health of people
are to be protected using preventive measures" (Directive 96/82/EC of the
Council "Seveso II"). Legislation also promotes "health and safety at work" (Ma-
chinery Directive, health and safety legislation). The objective to achieve these
and similar goals is specified in the appropriate EU Directives by legislative bod-
ies for various areas ("regulated area"). In order to achieve these objectives, the
legislative bodies place demands on companies operating plants and systems
and the manufacturers of equipment and machines. These legislative bodies
have at the same time allocated responsibility for possible damage.
A new concept ("new approach", "global approach") used as basis for the EU
Directives:
S
EU Directives only specify generally valid safety goals and define basic
safety requirements.
S
EU Directives specify that the Member States must mutually recognize do-
mestic regulations.
The EU Directives are all of equal importance, i.e. if several Directives are appli-
cable for a specific piece of equipment or machine, then the requirements of all
of the relevant Directives apply.
For a machine with electrical equipment, among others, the following apply
S
Machinery Directive 98/37/EC
S
Low Voltage Directive 2006/95/EC
S
EMC Directive 2004/108/EC
The European Machinery Directive is essential valid for all machines. The mini-
mum requirements are defined in Appendix I of the Directive. More detailed in-
formation is then provided in the harmonized European Standards – types A, B
and C.
The devices must be disposed off corresponding to the regulations valid in the
particular country!
