7.1.5 Hazard and risk analysis
This documentation can only accentuate the need for a hazard analysis. The user of
drive-based safety must concentrate on dealing with the standards and legal position.
Before putting a machine into circulation, the manufacturer of the machine must carry out
a hazard analysis according to the Machinery Directive 89/392/EEC to find out the hazards
related to the application of the machine. To achieve a level of safety as high as possible
the Machinery Directive contains three principles:
ƒ Removing or minimising the hazards by the construction itself.
ƒ Taking the protective measures required against hazards that cannot be removed.
ƒ Documentation of the existing residual risks and training of the user regarding
these risks.
The execution of the hazard analysis is specified in EN 1050, guidelines for risk assessment.
The result of the hazard analysis determines the category of safety-based control modes
according to EN954-1 whichthe safety-oriented parts of the machine control must comply
with.
7.1.6 Standards
Safety regulations are confirmed by laws and other governmental guidelines and
measures and the prevailing opinion among experts, e.g. by technical regulations.
The regulations and rules to be applied must be observed in accordance with the
application.
