S = Severity of injuryS1: Slight injury
S2: Serious injury, including death
F = Frequency and/or duration of exposure to the hazard F1: Seldom short exposure time F2: Frequent long exposure time
P = Possibility of avoiding the hazard P1: Possible under specific conditions P2: Nearly impossible
Selection of Categories B, 1 to 4
Preferred categories for the risk
Possible categories (may require additional measures)
Measures may be over-dimensioned for risk

Possible loss of safety function. Greater reliability, but possible loss ofsafety function.
Fault detected at each test. Safety function is ensured with a singlefault. An accumulation of faults is not
possible or detected.

Assessing Risk
Training Note
Implementing the Catagories (based on ISO 13849-1/EN 954-1)
Risk: A combination of the probability of occurrence of harm and the severity of that harm. (ANSI B11 TR3)
Severity of Harm
Occurrence Minor Moderate Serious Catastrophic
Remote — — Low Low
Unlikely — Low Medium Medium
