- 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.
|S||Severity of injury||Selection of Categories B, 1 - 4|
|S1||Slight||Preferred categories for reference points|
|S2||Serious (normally irreversible) injury, including death|
|F||Frequency and/or Duration of exposure to the Hazard|
|F1||Seldom to quite often, and/or short exposure time||Possible categories which may require additional measures|
|F2||Frequent to continuous and/or long exposure time|
|P||Possibility of avoiding the Hazard||Measures which can be over-dimensioned for the relevant risk|
|P1||Possible under certain circumstances|
|P2||Nearly impossible to avoid the hazard|
