Risk Components
 

Risk assessment is the combination of its two components - severity and likelihood.

  • Severity of possible damage from hazard or impact

  • Likelihood of that occurring

This involves some calculations - that look scientific, and some guesswork.

The severity of mercury pollution in water courses could be high

(as the result is people rolling around out of their minds) whereas the likelihood of it happening could be low (because you use very little and it is under controlled circumstances).
