Points system

Hazard severity Points Rating Definition
Nil 1 Very minor injury, bruise, graze, no risk of disease.
Slight 2 Minor injury, which would allow the individual to continue work after first aid treatment on site or at a local surgery. The duration of the stoppage or treatment is such that the normal flow of work is not seriously interrupted.
Moderate 3 Temporary disability causing injury or disease capable of keeping an individual off work for three days or more and reportable under RIDDOR
High 4 Causing death, serious injury or permanent disability to an individual.
Very high 5 Causing multiple deaths and widespread destruction eg. fire, building collapse.


Hazard likelihood Points Rating Definition
Remote possibility 1 There is really no risk present. Only under freak conditions could there be any possibility of an accident or illness. All reasonable precautions have been taken - This should be the normal state of the workplace.
Unlikely 2 This incident or illness might occur but the probability is low and the risk minimal.
Possible 3 The accident may occur if additional factors precipitate it, but it is unlikely to happen without them.
Highly likely 4 Will happen more often than not. Additional factors could precipitate an incident but it is still likely to happen without this additional factor.
Inevitable 5 If the work continues as it is, there is almost 100% certainty that an accident will happen, for example:

A broken stair or broken rung on a ladder Bare, exposed electrical conductors Unstable stacks of heavy boxes


Risk Rating Score Definition Action
1 to 4 Low No action required
5 to 9 Moderate Reduce risks if reasonably practicable
10 to 15 High Risk Priority action to be undertaken
16 to 25 Unacceptable Action must be taken IMMEDIATELY
