Long pants or a long dress/skirt must cover the legs. Shoes must completely cover the feet; sandals or other open footwear are not acceptable. Long hair and loose clothing must be confined or tied back. Lab coats are required and may be purchased from the Chemistry Department. 6. No smoking, eating, or drinking allowed in the laboratory. 7. Do not attempt unauthorized experiments. Check with your lab TA first. 8. Never smell, taste, or eat any chemical. Treat all chemicals as poisonous. Never pipet by mouth. 9. If a chemical should accidentally come in contact with the skin or eyes, flush immediately with large quantities of water and notify a lab instructor. 10. Dilute acids very carefully, always adding acid to water (not water to acid). Clean up spills immediately. Wear gloves when pouring concentrated acids or bases or other hazardous substances. 11. Never point a test tube at yourself or anyone else, especially while heating. Use boiling chips to prevent "bumping" while heating. Never heat an organic liquid with a burner in an open vessel. Do not used cracked glassware. 12. Before using any reagent, read the label carefully to be sure you have the right substance. Many distinctly different substances have similar names! 13.

Do not remove reagent bottles from their shelves or from the hoods to your lab bench. 18. Many solvents are toxic and/or flammable. Do not inhale solvent fumes. Before pouring ether or other volatile organic solvents from a bottle, make sure there are no open flames anywhere near you. Always close bottles after use. Clean up solvent spills as soon as possible; your lab instructor will help you. 19. Do not throw filter paper or other refuse in the sinks; waste receptacles are provided under the hoods at the ends of the laboratories. If organic liquids are accidentally spilled into a sink, wash them down with water immediately. Place any broken glass in the special boxes designated for broken glass.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
