  1. Lesson 5: Safety Meet Lyn. A few years ago Lyn was participating in an activity in her science class. She was instructed to blow out her candle and return it to the lab supply bench by walking around the outside of the student tables. After removing her goggles, Lyn blew out her candle (which was still hot) and walked directly through the student tables toward the supply bench. Her hot candle passed over the container of alcohol, dripped hot wax into the alcohol and caused an alcohol explosion. Lyn’s hair was burned and her long sleeve caught on fire burning her arm.

  2. Wear Laboratory Aprons when needed. Keep your work area clean and neat. Roll up long sleeves. Never mixed anything unless told to do so. Never taste anything in the lab! Last thing to do…wash hands. Pull long hair back. Remove contact lenses. PPEPersonal Protection Equipment Wear SAFETY GOGGLES over your eyes NOT on your head!

  3. Most common lab accidents involve broken glass. Broken Glass Sharp objects (like disposable glass pipets, cutting tools, broken glass, etc.) should be stored in a special “sharps” container. Tell the teacher. The teacher will clean up the glass. DO NOT CLEAN UP BROKEN GLASS YOURSELF.

  4. SPILLS Tell the teacher. The teacher will clean up the spill. DO NOT CLEAN UP CHEMICALS UNLESS YOUR TEACHER INSTRUCTS YOU TO DO SO.

  5. CORROSIVES are chemicals that can corrode (melt or burn away) surfaces.

  6. Point the tube AWAY from people. Heating test tubes: Hold the test tube with TONGS Wear GOGGLES

  7. If you get something on you or are hurt… TELL YOUR TEACHER IMMEDIATELY! DO NOT RUN TO THE RESTROOM! DO NOT PANIC. I cannot help you if you are panicked. I cannot help you there.

  8. COMPRESSED Gases = gases (like oxygen, nitrogen, hydrogen, etc.) that are stored under pressure in a tank. If the valve is damaged the tank can explode or become a projectile.

  9. Personal Protective Equipment (PPE) = equipment such as eyewear (goggles), clothing (lab coats, aprons), gloves (heat protectant, neoprene).

  10. Fume Hood = a vacuum to remove harmful chemical fumes/vapors.

  11. So, how do you safety smell chemicals? Wafting = the safe way to sample a chemical aroma is to use your hand to waft the fumes toward your nose. What if this was chloroform? She could end up like this! Lab Safety Rap

  12. Identify these safety symbols… Be able to identify all safety symbols shown on Text pg 1068. Flash Drive: Lab Safety Chem Games 16:30

  13. Eliminate any definitely wrong answers from a multiple choice question, even if you don’t know the correct question. Cross out the wrong choices (if allowed to write on the test). TEST ON L1-L6. I-Safe (view videos through Moodle) http://moodle.rcsnc.org/moodle/course/view.php?id=246 TEST TIPS!
