Some rules are NOT made to be broken. That is true of the rules used in a chemistry lab. They are really, truly for your safety and not your humiliation.
Do Not Pipette By Mouth – EverYou 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, right? 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!
Read the Chemical Safety Information
A Material Safety Data Sheet (MSDS) should be available for every chemical you use in lab. Visit www.creativesafetysupply.com and follow the recommendations for safe use and disposal of the material. 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!
Identify the Safety Equipment
And know how to use it! Given that some people (possibly you) will need them, know the locations of the fire blanket, extinguishers, eyewash, and shower. Ask for demonstrations! If the eyewash hasn’t been used in a while the discoloration of the water is usually sufficient to inspire use of safety glasses.
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 Casually Dispose of Chemicals Down the Drain
Some chemicals can be washed down the drain, while others require a different method of disposal. If a chemical can go in the sink, be sure to wash it away rather than risk an unexpected reaction between chemical ‘leftovers’ later.
Don’t Eat or Drink in Lab
It’s tempting, but oh so dangerous… just don’t do it!
