elements of the corrosion control engineering life cycle;
b) risk assessment is transparent and inclusive;
c) risk assessment is dynamic, iterative and responsive to change;
d) risk assessment takes human factors into account;
e) risk assessment is systematic, structured and timely.
5 Risk assessment procedure
5.1 General
The risk assessment process of a corrosion control engineering life cycle includes the following steps.
