  1. Be Safe! In the Chemistry Lab Dr. Deborah Yager CVHS Chemistry

  2. Basic Lab Safety Goggles must be worn anytime chemicals, heat or glassware are used. Hair must be tied back and dangling jewelry removed. All long sleeves must be removed or rolled back. Best footwear are closed-toed shoes, not sandals or open-toed shoes.

  3. Basic Lab Safety (cont) No food or drinks allowed at the lab benches. No horseplay during lab activities! No unauthorized lab experiments allowed. For success in the chemistry lab, always follow your teacher’s instructions!

  4. Working with Heat Sources We will work with two heat sources: bunsen burner hot plate (i.e. sleeve, long hair, or combustible chemicals such as alcohol) should never be placed near an open flame. Flammable materials

  5. Working with Heat Sources (cont) BEWARE!! Cold glass looks the same as ! hot glass “cold” plate hot plate Handle hot glass with tongs. When heating a substance in a test tube, point the open end of the tube AWAY from people.

  6. Laboratory Fire Safety If a laboratory fire erupts, notify your teacher immediately. Every classroom has a fire blanket. If an object on a person (i.e. sleeve or hair) catches fire, use the blanket. If necessary, stop, drop and roll. A fire blanketcan also be used to extinguish a burning object.

  7. Laboratory Fire Safety (cont) If a large laboratory fire develops, use afire extinguisher. Every classroom has a . fire extinguisher Our classrooms and hallways have Class C fire extinguishers, which can extinguish paper/wood and other combustibles, flammable liquids such as gasoline, and electrical fires. To use a fire extinguisher effectively, follow the PASS technique:

  8. P.A.S.S. Pull the pin. Aim low at the base of the fire. Squeeze the top handle or lever. Sweep from side to side until the fire is completely out.

  9. Chemical Safety All lab chemicals are to be considered dangerous. Follow instructions and report incidents to your teacher! Should you feel a chemical irritation on your skin or hands, wash the area immediately with water. If a large part of your body is involved, use the emergency shower located in your classroom. If a chemical burns your eye, use the emergency eye wash station. Chemical wash station

  10. Chemical Safety (cont) After completion of a lab activity, follow teacher instructions for chemical disposal. Chemical waste collection Some chemicals are safe to dispose of down the sink. Others require collection and proper disposal. Know what to do before doing it! In the event of glass breakage, never handle broken glass with your bare hands. Notify your teacher for assistance, and put broken glass in the glass waste box in Rm 768.

  11. Major Emergency In the event of a major emergency, such as an earthquake or fire, hit the Main Shutoff Switch located in the front of the classroom. Main Shutoff Switch This switch turns off all electricity to the classroom, and is only to be used in an emergency.

  12. Enjoy your chemistry explorations! Be Safe! Dr. Deborah Yager CVHS Chemistry
