Probability

To reduce the risk value one must initiate Probability-reducing measures.

• Example: Injury event. Possible Probability-reducing measures:
  • Proper and adequate training.
  • Using scaffolding rather than ladders when working at heights.
  • Covering of slippery outdoor areas in the winter.

The scale of probability in Qm+ is 1 - 5. The default values are:

SET 1

1. Less than one occurrence per 20 years

2. One occurrence per 10 years

3. One occurrence per year

4. One occurrence per month

5. One occurrence per week

Alternatively, customers can define their own texts. These are also available and can be used by setting the system preference RISKSCALE. Please note that the same set number will be used for both probability and consequence unless a different set number is defined for Consequence in the SPAN field.
