- All hazards are classified as ‘Serious’ (S2).
- The Frequency classification may be either F1 or F2, depending on the specific application.
- All hazards are avoidable and can be classified as P1.
- For usage that is ‘seldom to quite often’ (blue line), a safety level of Cat1 or Cat2 may be appropriate.
- For ‘frequent to continuous use’ (red line) the machine should be monitored to a Cat3 level.
- This is offered as a general guide only.
- Some companies have a policy that all new equipment be monitored to Cat3 or higher.
