1) assure maximum efficiency of treatment;

2) assure maximum safety to consumers;

3) provide maximum safety to operators;

4) chemicals that are incompatible are not stored or handled together;

5) all chemicals are delivered from the feeder to the point of application in separate conduits; and

6) chemical feeders and pumps operate at no lower than 20 percent of the feed range unless two fully independent adjustment mechanisms, such as pump pulse rate and stroke length, are fitted when the pump must operate at no lower than 10 percent of the rated maximum.

d) All chemical containers must bear the name, address and telephone number of the supplier, along with a functional name or identification and strength of the chemical.
