NSF North Mississippi GK-8 Why is Lab Safety Important? Lab safety is a major aspect of every lab based science class. Lab safety rules and symbols are needed so that students do not injure themselves or their classmates.

NSF North Mississippi GK-8 Lab Safety Rules 1. Always follow the teacher’s directions and only do lab work when a teacher is present. 2. Conduct yourself in a responsible manner at all times. No Horseplay! 3. Do not touch any equipment, chemicals, or other materials until told to do so. 4. Do not eat food, drink beverages, or chew gum in the lab.
