1. RISK ESTIMATION AND EVALUATION
RISK CLASSIFICATION USING A RISK SCORE TECHNIQUE
Exposure (E) How frequently does the hazardous event occur Risk level Continuously …………………………………………………………………………………………… 10 Frequently (daily) …………………………………………………………………………………… 6 Occasionally (weekly) …………………………………………………………………………… 3 Unusually (monthly) ……………………………………………………………………………… 2 Rarely (few a year) ………………………………………………………………………………… 1
Probability (P) The probability of a loss when the hazardous event does occur Risk level Frequent (happens often) ……………………………………………………………………… 10 Probable (quiet possible) ……………………………………………………………………… 6 Occasional (unusual, but possible )……………………………………………………… 3 Remotely possible (has happened somewhere) ………………………………… 1 Improbable (practically impossible) …………………………………………………… 0.5
Severity (S) Consequences of the hazardous event Risk level
Catastrophic many fatalities; or interruption of longer than 2 weeks; or asset or environmental damage (or both) exceeding R100m …………………… 100 Disaster (few fatalities; or interruption between one and 2 weeks; or asset or environmental damage (or both) exceeding R10m) ………………… 40 Very serious (one fatality; or interruption of 6 days; or asset or environmental damage (or both) exceeding R100,000 ……………………………… 7 Important (temporary disability; or interruption between 6 and 24 hours; or damage exceeding R10,000 ………………………………………… 3 Noticeable (first aid needed; or interruption of less than 6 hours; damage exceeding R1000) ……………………………………………………………………… 1
Risk classification (Risk score = E x P x S ) Risk score Risk level Over 400---------5 Very high risk – discontinue operation or activity 200 to 400 ------ 4 High risk – immediate correction needed 70 to 200------- 3 Substantial risk – correction needed 20 to 70--------- 2 Possible risk – attention needed Under 20 -------- 1 Risk accepted
