Summary Analysis
Risk assessment and risk minimization for plant and machines
This simplified description outlines the basics of risk analysis for planners and designers.
For more detailed information please consult the relevant norms.

Determining the limits of a machine
 Proper use
 Spatial limits (transport, assembly, installation, power supply, material feed)
 Temporal limits (working life, servicing intervals, ...)

Identifying dangers
 Crushing, shearing, electric shock, poisoning, burns, ...

Assessment of all danger situations
 Operator-machine relationship
 Operating states
 Servicing, maintenance, disassembly, disposal
 Wear
 Predictable misuse, ...

Risk assessment
 Extent of damage
 Persons in danger zone
 Probability of danger occurring
 Possibilities of avoiding/limiting damage

Select measures for risk minimization
 Design measures
 Technical measures
 User information, warnings, operating hints, ...

Determine residual risks
 Test effectiveness of safety measures
 Validate acc. to EN ISO 13849-2

If necessary introduce additional measures
to reduce residual risk to an acceptable level.
