Risk = Probability x Severity x Exposure
The overall risk inherent in a job is a function of three variables: probability, severity and duration.
Steps in a Risk Analysis
The greater the probability, severity and exposure - the higher the risk while doing a job. More on this later.
Probability
Probability describes the likelihood that a worker will be injured or become ill if exposed to a hazard. Common terms used to describe probability are:
- unlikely - Injury from exposure has low probability. Less than 50% chance.
- likely - Injury from exposure has moderate probability. 50/50 chance.
- very likely - Injury from exposure has high probability. Greater than 50% chance.
