Students should wear gloves in the lab, so why is it important for them to wash their hands after handling organisms or chemicals?

Explanation:

When we work in a laboratory then it is important to follow all the instructions carefully by understanding them properly.

Also, we work by wearing gloves in order to avoid any chemical contact with our skin. But these gloves do contain imperfections due to which some amount of chemical substance remain intact to our skin or hands.

As a result, when we remove gloves after the experiment then chemical still remains on our hands. Hence, they reach to the things that we touch.

Therefore, it is advisable to properly wash your hands after handling organisms or chemicals so that any kind of chemical remains also get washed off from our hands.
