You should wash your hands before returning to work after which of the following activities?

Washing your hands before returning to work after using the restroom or eating is crucial for maintaining hygiene and preventing the spread of germs. When you use the restroom, bacteria and viruses can be transferred to your hands, which can then contaminate surfaces, food, and other individuals if not properly cleaned. Similarly, after eating, your hands may come into contact with food residue, potentially leading to contamination. By washing your hands in these instances, you help ensure a healthier environment for yourself and others around you, reducing the risk of illness.

Engaging in other activities, such as typing on a computer, cleaning surfaces, or moving equipment, typically does not pose the same level of direct risk for transferring harmful pathogens to your hands, thus making handwashing less critical in those specific scenarios when compared to using the restroom or eating.
