warned them to be careful and reminded them to follow the safety rules from the contract they had received in
science class. Below you will find 16 of our class safety rules and 6 lab scenarios.
1. Read each of the 6 lab scenarios.
2. For your group’s assigned scenario, underline the sentences in the scenario that describe a safety rule
that has not been followed.
3. For each scenario, write the # ‘s of the safety rules (#1-16 from our safety rules) that were violated.
 Each scenario may have more than 1 rule violation.
 Each rule can be used in more than one scenario
4. After you indicated the rules that were violated, write a brief explanation as a group why those rules were
violated and what they should have done to follow that rule.
* CLASS SAFETY RULES *
1. All chemicals are considered dangerous. Do not touch, taste or smell anything unless you are told.
2. Anytime chemicals, heat, or glassware are used, students will wear lab goggles. No exceptions.
3. Clean all work surfaces, apparatuses and equipment at the end of the experiment. Return all equipment
clean and in working order to proper storage area. Never leave materials unattended.
4. Do not eat food, drink beverages or chew gum in the lab.
5. Do not point the open end of a test tube being heated at yourself or anyone else. Point it away.
6. Dress properly during a lab activity. Long hair must be tied back and dangling jewelry or loose/baggy
clothing should be secured, as these are hazardous in the lab.
7. Exercise extreme caution when using a gas burner. Keep hair, clothes and hands at a safe distance from the
flame at all times. Do not place substances into the flame unless told to do so.
8. Follow all written and verbal instructions carefully. If you do not understand a direction or part of a procedure,
ask the teacher before proceeding.
9. Keep hands away from face, eyes, mouth and body while using chemicals or specimens. Wash your hands
with soap and water after performing all experiments.
10. Never fool around or run around in the lab. This is dangerous and prohibited.
11. Never handle broken glassware with your bare hands. Brush into a dustpan to clean up broken glass. Place
broken or waste glassware in the designated glass disposal container.
12. Never look directly into a container that is being heated
13. Never smell a substance directly. Always “waft” it.
14. Never work alone, perform an experiment or mix chemicals together without a teacher present. Follow all
instructions in the lab you are given and instructions that the teacher explains.
15. Report any spill, breakage, cut or burn to the teacher immediately, no matter how minor it may seem.
16. Work areas should be kept clean and tidy at all times
