The graphic explains how risk levels can be classified using numbers and colour coding. In this
example, green identifies a low risk and red identifies a high risk and intermediate risks are
show in orange.

Numerical rating system such as the example shown above can be useful for numerous
reasons:

Clarity of thinking – careful consideration given on the likelihood and severity of foreseeable
injury when they matrix system, it gives accurate outcome.

Consistency of approach – the outcome will be of similar results, even if it is used by different
people.

Prioritisation – the risk level is represented by number, and the higher the number the greater
the risk, it is also possible to categorize risks presented by the hazards and rank them with
sequence.

Qualitative Risk Assessment

The simplest way to quantify the risk is low, medium or high:

Low risk: This is where the likelihood of an accident occurring is
low and the severity is low. For example, intermittent work on a
computer where the workstation is well laid out is unlikely to
result in any harm to the user.

Medium risk: As the level of likelihood and severity increases, a
hazard may be assessed as a medium risk. For example, manual
handling of heavy loads without mechanical aids. You should use
control measures to reduce these hazards to low risk.

High risk: You should focus on high risk hazards first, as there is a
likelihood that an accident could occur and if it does then there
could be serious injuries, ill health or death. For example, vehicles
reversing where pedestrians / members of the public are walking.

Risk Reduction through prevention and control measures

Risk assessment steps evaluate the adequacy of existing control measures in place. Thought
must be given whether they achieve the principles of prevention with reference to hierarchy of
control.
