2. Apply soap: Employees should apply soap to their hands, making sure to cover all areas, including the backs of their hands, between their fingers, and under their nails.
3. Rub hands together: Employees should rub their hands together for at least 20 seconds, using friction to remove dirt, bacteria, and chemicals.
4. Rinse hands: Employees should rinse their hands thoroughly under running water, making sure to remove all soap and residue.

6. Use hand sanitizers: Employees can also use hand sanitizers when hand washing facilities are not available, making sure to use enough sanitizer to cover all areas of their hands.
7. Wear gloves: Employees should wear gloves when handling food or chemicals, and should wash their hands before and after wearing gloves.
8. Dispose of gloves: Employees should dispose of gloves after use, making sure to follow proper disposal procedures for contaminated gloves.
