About www.AmericasRight.com
SAFETY GLASSES always wear safety glasses, never stand too close to container when sodium or potassium is dropped into water. Never stand next to container and do not drop more than 1/2 gram into water.
Long pants are preferable to shorts or short skirts. Tie long hair back. Wear safety goggles and a lab coat. Even if you aren't clumsy, someone else in the lab probably will not pay attention to the instructor and do something stupid. Don't let that person be you.
Always pay attention to your instructor.
If you take even a few chemistry courses you will probably see people accidently set their lab coat on fire, spill acid on their lab coat, others, or notes, splash themselves in the eye, etc. Use caution and follow your instructors directions and you will be fine.

Don't haphazardly mix chemicals! Always have adult supervision.

Don't Play Mad ScientistDon't haphazardly mix chemicals! Pay attention to the order in which chemicals are to be added to each other and do not deviate from the instructions. Even chemicals that mix to produce seemingly safe products should be handled carefully. For example, hydrochloric acid and sodium hydroxide will give you salt water, but the reaction could break your glassware or splash the reactants onto you if you aren't careful!
Do Not Pipette By Mouth - Ever
You say, "But it's only water." Even if it is, how clean do you think that glassware really is? Using disposable pipettes? I know lots of people who rinse them and put them back! Learn to use the pipette bulb or automated pipetter.
Don't pipette by mouth at home either. Gasoline and kerosene should be obvious, but people get hospitalized or die every year?
I know someone who used his mouth to start the suction on a waterbed to drain it. Do you know what they put in some waterbed additives? Carbon-14. Mmmm...radiation. He couldn't retch fast enough! The lesson is that even seemingly harmless substances may be dangerous!
Dress Appropriately (for chemistry lab, not fashion or the weather)
No sandals, no clothes you love more than life, no contact lenses, and long pants are preferable to shorts or short skirts. Tie long hair back. Wear safety goggles and a lab coat. Even if you aren't clumsy, someone else in the lab probably is. If you take even a few chemistry courses you will probably see people set themselves on fire, spill acid on themselves, others, or notes, splash themselves in the eye, etc. Don't be the bad example to others, remembered for all time for something stupid!
Don't Taste or Sniff Chemicals
For many chemicals, if you can smell them then you are exposing yourself to a dose that can harm you! If the safety information says that a chemical should only be used inside a fume hood, then don't use it anywhere else. This isn't cooking class - don't taste your experiments!
Don't Eat or Drink in Lab
It's tempting, but oh so dangerous... just don't do it!
Always have adult supervision. Never place sodium or potassium in glass beacker use a nonshattering container.
