It must be appreciated that risk assessment is not a precise science.
What may be a risky operation for one person may be a matter of common sense for another. It is necessary, therefore, to quantify the risks in a way that is understandable and credible to all concerned.
There are many systems that can be used to determine the risk associated with a hazard within the workplace. A simple and effective way of identifying and prioritising those hazards that require further control is by use of a numerical system such as that detailed below.
A Numerical System
(something with the potential to cause harm). May be quantified as:
- 3 = fatal
- 2 = major injury
- 1 = minor injury
(the likelihood of that harm being realised). May be quantified as:
- 3 = very likely
- 2 = likely
- 1 = unlikely
Consequently, the significance of a hazard may be calculated as: Probability x Hazard. For example:
|Hazard||Persons Affected||Hazard||Probability||Hazard x Probability|
|Tipping the Forklift Truck||Drivers and People||3||2||= 6|
|Dermatitis From Using Bactericidal Detergent||Kitchen Staff||1||3||= 3|
|Beer Line Cleaner Splashed In Eyes||Head Barman and Bar Steward||2||2||= 4|
The interpretation of the results may be given as:
