9.6.3 Safety technology and standards
The objective of safety technology is to keep the potential hazards for man and
the environment as low as possible by applying the relevant technology.
However, this should be achieved without imposing unnecessary restrictions on
industrial prooduction, the use of machines and the production of chemical
products. By applying internationally harmonized regulations, man and the
environment should be protected to the same degree in every country. At the
same time, differences in competitive environments, due to different safety
requirements, should be eliminated.
Legislation states that we must focus our efforts ”...at preserving and protecting
the quality of the environment, and protecting human health through preventive
actions” (Council Directive 96/82/EG on the control of major accident hazards
involving dangerous substances “Seveso II”). Legislation demands that this
and similar goals are achieved for various areas (areas which are legislated”) in
the EC Directives. In order to achieve these goals, legislation places demands
on the operators and users of plants, and the manufacturers of equipment and
machines. It also assigns the responsibility for possible injury or damage.
The EC Directives provide a new global concept (“new approach”, “global ap-
proach”):
S EC Directives only contain general safety goals, and define fundamental
safety requirements.
S EC Directives specify that Member Stages recognize each other’s national
regulations and laws.
The EC Directives have the same degree of importance, i.e. if several Directives
apply for a specific piece of equipment or device, then the requirements of all of
the relevant Directives have to be met.
For a machine with electrical equipment, the following apply.
S Machinery Directive 98/392 EC
S Low–Voltage Directive73/23/ECG
S EMC Directive 89/336 EC
The European Machinery Directive applies for all machinery. The minimum
requirements are defined in the Appendix I of the Directive. More detailed
information is provided through the European, harmonized standards, types A,
B and C.
