HYGIENE - PERSONAL
- food or drink should not be consumed
in the laboratory.
- food should not be left lying on
benches or stored in laboratory refrigerators. Both represent a
potential source of contamination.
- smoking should never be allowed in the
laboratory. Cigarettes, cigars or pipes represent a possible

- the application of cosmetics should be
