14. KNOW WHAT IS EXPECTED Read everything thoroughly before you begin doing anything. No food, gum or beverages. Co ver any open cuts or sores with a bandage. Re port all accidents immediately to your teacher. Wear safety goggles.

15. PREPARE A CLEAN WORK AREA Bring only essential materials to your work area Keep aisles clear No running Do not leave experiments unattended and extinguish burners when away from desk WAIT FOR PERMISSION TO START All experiments performed in the Science lab must be performed under the supervision of the teacher

16. USE COMMON-SENSE

17. Touch substances only when told to do so Smell substances using the proper technique - wafting Pour substances properly and safely GENERAL SAFETY If you are acting inappropriately, you will not be allowed to participate in the lab and risk participation in future labs. Your parents will be called. Tell your teacher immediately if you break any glassware. Never use cracked or chipped glassware. Do not run cold water over hot glass. It may shatter. Do not put hot glassware on the lab bench. Wait for it to cool down first. Always keep the open end of the test tube pointed away from everyone. Never allow any container to boil dry. GLASSWARE PRECAUTIONS

18. Clean up all spills immediately Clean up work area and return all equipment and materials as directed by your teacher Use the chemical waste bins to dispose of harmful chemical substances CLEAN-UP AND DISPOSAL

19. Rinse off substances immediately that come into contact with skin or clothing Wash hands before and after handling substances and before leaving the Lab Treat burns using cold water or ice Make sure you know how the eyewash station works. FIRST AID
