The correct answer to this question is right. There are many reasons why it is essential to wear a lab apron at all times. Working in a lab poses the risk of exposure to harmful chemicals. When a lab apron is a work, it protects the person from the substances, especially in the event a spill should happen.
Not only could a chemical spill stain clothing, but it could burn the person's skin. Usually coming in the color white, lab coats have become a permanent fixture for those working in the field of chemistry, as scrubs are essential for those in the medical field.
