List two lab safety rules
- Get rid of clutter! On lab days, do not bring anything to the classroom except the books and materials you will need to complete the lab. Extra books, jackets, sweaters, and unnecessary materials will only get in the way of experiments. They also cause a potential hazard.
- Secure loose clothing, jewelry, and long hair (past shoulder-length). Avoid wearing sandals or open-toed shoes in a lab environment. They will not protect your feet if a chemical is spilled or a sharp object is dropped.
- Always wear safety goggles throughout a lab that requires chemicals or sharp objects. You may also want to consider using a lab coat/apron or gloves.
- Never eat or drink anything in the lab. Do not chew gum during lab experiments.
