A hand washing sink in the break room is not an appropriate location for washing hands after working with human material in the laboratory.
A vital part of laboratory safety is hand washing. In fact, this 20-second method is regarded as one of the most crucial steps utilized to stop chemicals, radioactive materials, and microbiological agents from infecting you and the area around you.
Even though gloves should be used when handling hazardous items, adequate hand washing should still be done on a regular basis. If you don't wash your hands right away after taking off your gloves, germs could spread to your mucous membranes and infect you, or they could contaminate neighboring surfaces and endanger other lab workers.
Every laboratory that uses chemical or biological agents must have access to at least one sink for hand washing, ideally close to the room exit. To prevent contamination, the sink must be cleaned frequently, and soap must be available for hand washing.
