In order to find out what part of a building product or system may have a high risk associated with it, a risk analysis must be carried out.
To ensure the analysis is carried out on a consistent basis, a risk assessment methodology is usually used.
The method BEAL recommends is the risk analysis process that weighs the total risk score of the three most important characteristics of a situation, namely:
When a matrix of the above characteristics are given values and those values are used in a calculation, a relative ‘risk score’ is arrived at, allowing the risks of a building product to be ranked according to the risk score. From this it can be determined what characteristics need to be assessed and or tested to verify compliance with the performance requirement described in the Building Code.
