Standard Precautions: Handwashing

Health care provider washing hands.Frequent and thorough handwashing is the best way to prevent infection. The sooner you wash your hands after exposure, the less likely you are to catch or spread infection.

When to wash your hands

Wash your hands regularly throughout the day, especially:

  • When first arriving at work and before leaving

  • Before and after treating a patient

  • After touching blood or any other body fluid or substance, broken skin, or mucous membranes

  • After touching an object or surface that is or may be contaminated

  • Before and after eating, drinking, smoking, and after using the restroom

  • After coughing, sneezing, or blowing your nose

How to wash your hands

First, carefully remove gloves and other PPE. Follow your facility’s guidelines for dealing with jewelry. Then follow these steps:

  • Use warm water and plenty of soap. Work up a good lather by rubbing your hands together.

  • Clean your whole hand, under your nails, between your fingers, and up your wrists. Wash for at least  20 seconds (CDC guidelines).

  • Rinse your hands well. Let the water run off your fingertips, not up your wrists.

  • Dry your hands well with clean paper towels. Or use an air dryer machine. If you can, use paper towels to turn off the faucet and open the door so you don’t recontaminate your hands.

  • If no sink is available, use the alcohol-based handwashing cleanser approved by your facility. Be sure it contains no less than 60% alcohol. These products are fast-acting and significantly reduce the number of germs on the skin. Unfortunately, they don't work on all types of germs in the hospital. Wash with soap and water as soon as you can.

Remember: When you wash your hands, the longer you wash, the more germs you’ll remove. Time yourself the next time you wash your hands. It may take longer than you think to get rid of germs.
