Safety
Please be sure read everything carefully. We have a number of safety procedure and common sense guide lines that should always be followed when working in any laboratory even if that lab is your kitchen. In every lab there is always the danger that you may expose yourself to injury. The chemicals and equipment that you use and the way that you use them are very important, not only for your safety but for the safety of those working around you. Please follow these rules at all times. Failure to do so increases your risk of accidents.

1. Safety Goggles: All students are required to have and wear safety splash goggles during lab procedures and especially when chemicals are being heated or mixed. If others are watching you perform the procedure, they too will need to wear safety goggles, otherwise they should not be in the area. Safety glasses will protect your eyes from chemicals that spatter or explode. Running water should be available. If you happen to get a chemical in your eyes, flush thoroughly with water for 15 minutes. If irritation develops, contact a physician. Take the lab procedure instruction and the bottle of chemical with you to the doctor’s office. Goggles are available for purchase at the bookstore. 2. Chemical Contact with Skin: Your kit contains protective gloves to wear whenever you are handling chemicals. If you do happen to spill a chemical on your skin, flush the area with water for 15 minutes. If irritation develops, contact a physician. Take this book and the bottle of chemicals with you. 3. Smelling Chemicals: If you need to smell a chemical to identify it, hold it six inches away from your nose and wave your hands over the opening of the container toward your nose. Waft: some of the fumes toward your nose without exposing you to a large dose of anything really stinky or dangerous. Under no circumstances are you to taste any of the chemicals used in these experiments. 4. No Eating or Drinking During the Lab : When you ear or drink, you run the risk of ingesting strange chemicals. Make sure your hands and lab area are always clean when you are finished experimenting. 5. Clean up all Messes Immediately: This is not time to be a pig. Your lab area should be spotless when you start experimenting and spotless when you leave. If not, clean it. 6. Proper Disposal of Poisons: If a poisonous substance is used or formed during the experiment in this lab, the lab...
