Description
The event cannot happen under any circumstances.
The incident may occur only in exceptional circumstances
The incident is not expected to happen but may occur in some
circumstances
The incident may happen occasionally
The incident is likely to occur, but is not a persistent issue
The incident will probably occur on many occasions and is a persistent
issue

Short term injury/damage (e.g. resolves in a month); a number of people
are involved
Semi permanent injury (e.g. takes up to year to resolve)
Permanent injury; major defects in plant, equipment, drugs or devises; the
incident or individual involved may have a high media profile

By using the matrix above the risk score can be calculated to determine risk category. This ranges
ranging from 1 (low severity and unlikely to happen) to 25 (just waiting to happen with disastrous and
widespread consequences). The risk score can now form a basis upon which to determine the urgency
of any actions.

*Risks which have a priority score of 9 or more should be reviewed by the Directorate Management
Team immediately. Risks with a score of 15 or more must be notified to the Risk Manager
1. Severity
The severity of the outcome should be considered as follows:A.
Likely to result in fatality
score 5
B.
Likely to result in a serious injury
score 4
C.
Likely to result in time being lost
score 3
D.
Likely to result in a minor injury
score 2
E.
No injury probable
score 1
2. Probability
The next consideration is the probability of the event happening. This may well depend on the
number of times the task is carried out and by whom.
The following figures should be used:-
A.
Very likely to occur
score 5
B.
Probably will occur
score 4
C.
Possibility of it occurring
score 3
D.
Small chance of it occurring
score 2
E.
No likelihood of occurrence
score 1
3. Assessment figure
The overall assessment figure should give some indication as to how soon the risk is
controlled and is obtained by multiplying the severity with the probability. It also indicates
numerically where the action should be. A suggestion is as follows:Score
21
- 25
WORK MUST NOT TAKE PLACE
Score
