|---|---|---|---|---|---|
| Fractional value | Possibility of accident | Fractional value | Frequency | Fractional value | Consequence |
| 10 | It’s perfectly predictable | 10 | Continuous exposure | 100 | Catastrophe, and multiple deaths (10 or more) |
| 6 | Quite possible | 6 | Exposure during daily working hours | 40 | Disaster, several deaths (3-9 people) |
| 3 | Possible, but not often | 3 | Once a week, or accidental exposure | 15 | Very serious, 1-2 people died |
| 1 | Unlikely, completely unexpected | 2 | Monthly exposure | 7 | Serious serious injury and disability (disability level 1-4) |
| 0.5 | It’s impossible. It’s conceivable | 1 | Several exposures per year | 3 | Serious injury and disability (disability level 5-6) |
| 0.2 | Highly unlikely | 0.5 | Very rare exposure | 2 | Minor injury (disability level 7-10) |
| 0.1 | Practically impossible | 1 | Minor injury | ||
Note: D ≥ 0 is a major hazard source.
