What is the first thing a food handler should do when preparing a three compartment sink for dishwashing?

The food handler should ensure that all the three compartments in the sink are rinsed and cleaned prior to use. This is necessary in order to ensure that the sinks do not harbor any pathogen that can be transferred to the dishes. The right water temperatures should also be maintained in all the three sinks.
