Presentation transcript:

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. Meet Lyn. Lesson 5: Safety

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

Broken Glass 1.Tell the teacher. 2.The teacher will clean up the glass. DO NOT CLEAN UP BROKEN GLASS YOURSELF. 1.Sharp objects (like disposable glass pipets, cutting tools, broken glass, etc.) should be stored in a special “sharps” container. Most common lab accidents involve broken glass.

SPILLS 1.Tell the teacher. 2.The teacher will clean up the spill. DO NOT CLEAN UP CHEMICALS UNLESS YOUR TEACHER INSTRUCTS YOU TO DO SO.

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

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

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

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.

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

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

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

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

TEST TIPS! 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)
