Which approach to hazard assessment uses mathematical functions or equations?

• Quantitative approach

• Deterministic approach

• Qualitative approach

• Probabilistic approach

When is it appropriate to use the qualitative approach to hazard assessment?

• When there is a lack of enough data for quantitative evaluation.

• When estimating the probability of each hazard affecting an area or region.           

• When a variable cannot be expressed as numerical.

• When past impact data can be combined with current conditions and potential exposure

       levels.
