Hand washing: Wet hands and wrists under warm running water. Apply liquid soap and lather well. If you use bar soap, keep it separate for your own use. Rinse the bar soap before and after you use it to remove the lather. Scrub hands and wrists for at least 20 seconds. Pay special attention to fingers, fingernails, and the back of your hands. Rinse hands well with your hands up. This keeps the dirty water running away from your hands. Dry your hands using a clean paper towel, starting with the hands and working down towards the elbows. Use the paper towel to turn off the faucet. Remember, you turned it on with dirty hands.
