Sanitation

Proper sanitation goes hand-in-hand with good laboratory housekeeping. Applying cosmetics, eating, drinking, and similar actions increase the risk of contamination. Observe the following guidelines:

1. Do not store or consume food or beverages in laboratories or near chemicals.
2. Do not smoke in laboratories.
3. Do not apply cosmetics in the lab.
4. Avoid chewing gum in lab.
5. Avoid smelling and never taste chemicals.
6. Oral pipetting or mouth suctioning is a prohibited practice.
7. Remove gloves and wash hands prior to leaving the laboratory, except in the case of an emergency. Use a new pair of gloves upon returning to the lab.
8. Leave lab coats in the laboratory. Place soiled clothing or lab coats in a closable bag or container when transporting for laundering or proper disposal.
9. Wash exposed skin of hands and arms thoroughly before leaving the laboratory. Use soap and warm water and rub hands for at least 20 seconds. Rinse thoroughly with fingers pointing downward under water stream.
