Risk assessment as per EN ISO 13849-1
S
– Severe physical injury
S1 = minor, reversible injury
S2 = severe, irreversible injury
F
– Frequency and/or duration of exposure
to danger
F1= rarely, not cyclic
F2 = frequently up to permanent and/or long
duration, cyclic operation
P
– Possibility to avoid the danger
P1 = possible, slow movement / acceleration
P2 = hardly possible, high acceleration in
case of a fault

Startpunkt
Abschätzung der
Risikominderung
C = Risikoparameter der Auswirkung
F = Risikoparameter der Häufigkeit und Aufenthaltsdauer
P = Risikoparameter der Möglichkeit, den gefährlichen Vorfall
zu vermeiden
W = Wahrscheinlichkeit des unerwünschten Ereignisses
The risks to be examined can also be found in applicable regulations and standards, or must
be considered separately by the manufacturer based on his specific knowledge of the
machine.
For machines sold within the EU the minimum risks to be examined are specified in the EU
machine directive 2006/42/EU or in the latest version of this directive.

C = Risk parameters of the effect
F = Risk parameters of the frequency of the dwell time
P = Risk parameters of the possibility to avoid the dangerous incident
W = Probability of the undesired event
- = no safety requirement
a = No special safety requirements
b = a single E /E /P E S is not sufficient
