Question

give two reasons why it is important to wash your hands both before and after completing a lab.

Answer 1

Keeping hands clean is one of the best ways to prevent the spread of infection and illness. You can contaminate your results if you work a lab with dirty hands. If you do not wash them after performing an experiment, you can be risking your own health, and/or the safety of others.
