ISO12100:2010 ‘ Risk assessment and risk reduction ’, is a standard issued by the
International Standards Organisation. It describes procedures for identifying hazards and
estimating and evaluating risks during relevant phases of a machine life cycle.
As with all powered industrial equipment, some hazards will remain despite any
precautions undertaken by the manufacturer or owner of the machine. It is essential that
operators are aware of these residual hazards and what they must do to prevent harm to
themselves or to others, as set out in
§6.3.3 .
6.3.1 The ISO12100 risk assessment model
In the ISO12100 risk assessment model, each identified hazard is given a Risk Factor , from
which is derived a Risk Evaluation . These parameters are assessed as follows.
6.3.1.1 Determining Risk Factor
The Risk Factor associated with a given hazard may be calculated using the following table,
with the formula:
LO x FE x DPH x NP = RISK FACTOR
6.3.1.2 Risk Evaluation
Once the Risk Factor is determined, the risk can be evaluated using the following table.
Risks evaluated as Very High, Extreme or Unacceptable are likely to require customised
operating procedures or additional safety functions.
