# 8.2.5  Identify the control measures needed for each risk

This means identifying the precautions (control measures) that need to be in place to eliminate or minimise the risks to the water supply system. So, in the example above, you would need to have a system of stock control that tells you when chlorine stocks are running low. Stock control may use some form of manual record keeping in a book or an electronic system (Figure 8.7). These have to be checked for effectiveness, as part of the Plan, and improved if necessary.
