THE KINNEY METHOD: HOW IT WORKS The risk (R) assessment, after Kinney, is done considering three parameters: the probability (P) of an accident or damage occurrence, the exposure at risk frequency (F) and the gravity (G) of the induced consequence. The probability of the damage occurrence during the exposure to a risk factor describes the accidental, stochastic and uncertain character. Kinney have defined 7 probability classes, to whom he allocated certain numerical values. The Kinney method: the risk ranking scale: Risk level (R) Risk class Required action, < 20 Very low Acceptable risk: no measure required. 20 - 70 Possible Monitoring. 70 - 200 Significant Measures to be taken. 200 - 400 High Immediate improvement. > 400 Very high Activity cessation. The exposure frequency expresses the time lapse in which the worker is exposed to the risk factor action,; this component is estimated by one of the 6 classes.
