- | ===Method=== | ||
- | |||
- | A risk analysis consists of the next elements: | ||
- | - Asset that has effect on the objectives, e.g., supplier, input file, producer, applications, | ||
- | - Situation with regard to the asset that can cause an event | ||
- | - Event that can take place that has a negative effect on the objectives | ||
- | - [[general_term/ | ||
- | - Exposure: frequency that the situation can occur | ||
- | - Probability: | ||
- | - Severity: gravety of the effect on the objectives | ||
- | - Risk-index: Exposure x Likelyhood x Severity | ||
- | - Additional [[general_term/ | ||
- | The Fine and Kinney method shows which values should be assigned to exposure, probability and severity. | ||
- | |||
- | ==Exposure (E)== | ||
- | The factor exposure indicates the duration that a risk can occur. The scale varies from 0.5 to 10.\\ | ||
- | * 0,5 Very rarely (less than once a year) | ||
- | * 1 Rarely (yearly) | ||
- | * 2 Sometimes (monthly) | ||
- | * 3 Occasionally (weekly) | ||
- | * 6 Frequently (daily) | ||
- | * 10 Constantly (multiple times a day) | ||
- | |||
- | ==Probability (P)== | ||
- | The probability or (mathematical) chance an incident will occur. The expectation is represented by ascribing a value from 0.1 to 10. | ||
- | * 0,1 Next to impossible / unthinkable | ||
- | * 0,2 Almost unimaginable | ||
- | * 0,5 Highly unlikely, but conceivable | ||
- | * 1 Unlikely, but possible in the long term | ||
- | * 3 Unusual (but possible) | ||
- | * 6 Possible | ||
- | * 10 To be expected | ||
- | |||
- | ==Severity (S)== | ||
- | The factor severity indicates the possible damage, effects and consequences linked to a hazard. The scale reaches from 1 to 40. | ||
- | * 1 Slight effect | ||
- | * 3 Important effect | ||
- | * 7 Severe effect | ||
- | * 15 Very severe effect | ||
- | * 40 Disaster | ||
- | |||
- | ==Risk-index (R)== | ||
- | The result of multiplying the parameters defines the risk-index: R = S x E x P. | ||
- | |||
- | ==Classification Risk-index== | ||
- | * R < 21 Slight risk; acceptable | ||
- | * 21 < R = 71 Little risk; attention required | ||
- | * 71 < R = 201 Moderate risk; apply simple measures | ||
- | * 20 < R = 401 High risk; apply large measures immediately | ||
- | * R > 401 Risk is too high; stop activities / operations | ||
