  2. Reasons for • Science is a hands-on laboratory class. • You will be doing laboratory activities, which require the use of hazardous chemicals and expensive lab equipment. • Safety in the science classroom is the #1 priority. • A signed lab safety contract and a score of 100% or better on the safety test are required to participate in labs.

  3. General Safety Rules • Follow all instructions given by the teacher. Do not touch anything before the instructions are given. • Wear safety goggles to protect your eyes from chemicals, heated materials, or things that might be able to shatter. • Notify your teacher if any spills or accidents occur.

  4. After handling chemicals, always wash your hands with soap and water. • During lab work, keep your hands away from your face. • Tie back long hair.

  5. No loose clothing or opentoed shoes. • Keep your work area neat and clean. 9. Clean up your lab area at the end of the laboratory period.

  6. Never eat or put anything into your mouth during a lab experiment. • Never “horse around” or play practicaljokes in the laboratory.

  7. Glassware Safety • Report chipped or cracked glassware to the teacher. • Broken glassware is thrown away in a special glass disposal container, not the classroom trashcan. • Always keep glassware at least a hands breadth from the edge.

  8. If a piece of glassware gets broken, do not try to clean it up by yourself. Notify the teacher. • Do not place hot glassware in water. Rapid cooling may make it shatter.

  9. If you get a cut: 1. Tell the Teacher. 2. Cover with a clean paper towel and apply pressure. First Aid for Cuts

  10. Chemical Safety • Wear protective goggles and a lab apron whenever using chemicals. • Never mix chemicals together unless you are told to do so. • Never taste any chemicals. All chemicals, including food, in the lab are considered hazardous. • If you need to smell the odor of a chemical, waft the fumes toward your nose with one hand. Never directly inhale the fumes.

  11. Always pour acid into water. Remember alphabetical order, A to Z. • Follow the instructions of your teacher when disposing of all chemicals. • Wash your hands after handling any chemicals. • Never take any chemicals from the lab or store room.

  12. If someone gets poisoned: Stay calm, and tell the teacher. Identify the chemicals that you were using. If someone spills a chemical on them: Tell the teacher. Flush the area with running water. First Aid

  13. Electrical Safety • Lay electrical cords where no one can trip on them or get caught in them. • Be sure your hands and your lab area are dry before using electrical equipment. • Never poke anything into electrical outlets. • Unplug cords by pulling the plug and not the cord. • Unplug all electrical equipment at the end at the end of the labperiod.

  14. If someone gets an electrical shock: Tell the teacher. Shut off the current at the source. Remove wire with rubber gloves. First Aid

  15. Heating Safety • Let burners and hotplates cool down before touching them. • Use tongs and/or protective gloves to handle hot objects. • Never reach across an open flame or burner. • Always point the top ends of test tubes that are being heated away from people.

  16. Only dry glassware should be heated. • Heat glassware by placing it on a wire gauze platform on a ringstand. Do not hold it in your hand. • Hot plates or glassware do NOT turn red when they are hot! • Never leave a burner or hotplate unattended.

  17. If someone gets burned: Tell the teacher. Immediately flush with cold water until burning sensation is lessened. First Aid

  18. If someone faints: Provide fresh air and have the person recline so that their head is lower than the rest of their body. http://videos.howstuffworks.com/r-fainting-farm/5106-fainting-goats-video.htm First Aid

  19. If someone gets something in their eye: Flush eyes immediately with plenty of water for 15 minutes. If a foreign object is lodged in the eye, do not allow the eye to be rubbed. First Aid
