risk assessment

RISK = Exposure x Severity x Probability

回复 1# Faurecia. ExposureThe frequency of exposure indicates how often a dangeroussituation can arise. It could be exposure to a toxic chemical orthe working and handling of a dangerous machine.
Exposure Factor
Very Rarely

(< 1/year)0.5
Rarely
( few times per year)1
Sometimes
( once or twice month)2
Now and then
( 1/week)3
Frequently
( 1/day)6
Continuous
(>2/day)10

SEVERITY

SEVERITY *Factor
Minor (injury without lost time/work restriction) FR21
Major (injury with external medical treatment/work restriction) FR14
Serious (injury with lost time) FR07
Critical (one fatality – instantly or afterwards) FR015
Disaster (multiple fatalities – instantly or afterwards) FR040
Take into account the measures defined, and based on those,determine the realistic maximum severity factor (based on practicalcase scenario)

PROBABILITYThe probability indicates how big the chances are that the effect (as defined inthe Severity table) might indeed occur. This is a subjective judgment, the mostdifficult assessment to make.
PROBABILITYFactor
Virtually Impossible (>20 y, once in a life time, only theoretical case )0.2
Conceivable but improbable, once in a career (1/20y)0.5
Improbable/borderline case, (1/10y)1
Unusual, One can think of a (unusual) scenario (1/3y)2
possible (once every 6 months)3
To be expected (once per week)10
As a guideline, if you can think of a scenario were the considered effect willoccur, the probability factor typically equals 3.

CLASSIFY INTO RISK CATEGORY:By calculating the hazard score it is then possible to classify it into thecorrect risk score category and thereby determining which possibleurgent plan of action is to be taken.

Risk score（R）InerpretationPriority for the measuresto be taken
<20Very limited risk - acceptable4
20 to 70Measures required (in 6m)3
70 to 200Immediate measure required2
> 200Stop work until measures taken1
Only R<20 can result in an acceptable situation where nothing(additional) needs to be done. However as long as S >= 4 additionalmeasure are strongly recommended.

我公司在用的风险评价计算方法，比较切合实际。
