Safety Quiz

Click on the correct answer

1 Safety is based entirely on attitude and training.
True: if you ain't got no attitude, them chemicals will just run all over you!
False: safety is instinctual and self-preservation will always help you do the right thing.
True: both are crucial, since training helps you know what to do, and attitude keeps you alert and aware of problem situations
False: my attitude is just fine the way it is and I took the training course which I didn't even need.
True: of course you have to train your attitude to get it just right so the chicks (guys) love you!

2 You light the bunsen burner to heat a test tube and wave it too close to a 500 mL beaker with 50 mL ether in it. It catches on fire. You quickly:
Run from the lab screaming like a banshee!
Grab the fire extinquisher (where is it in the lab anyway?) and douse the beaker with a wicked strong spray of whatever.
Grab the beaker with your bare hands (what a man!), run to the shower and turn it on.
Yell "Fire! Fire!" at the top of your lungs, run out into the hallway and pull the fire alarm.
Gently cover the beaker with a cloth or book to smother the flame.

3 You want to heat a test tube of caprolactam (a low melting solid) to polymerize it into nylon 6, so you:
Light a bunsen burner, hold the bottom of the test tube in the flame until the reaction is over.
Using a bunsen burner, gently move the tube in and out of the flame till it melts; continue this process carefully so as not to overheat.
Put the test tube in a beaker of hot water and swirl it around till the liquid melts and reation takes place.
Gently breath on the test tube, alternating this with holding it under your arm pit until the reaction is done.
Wave the test tube in the air very fast so that friction will heat it and complete the reaction.

4 You need to heat a solution of several chemicals in an organic solvent to make a reaction proceed so you:
Put everything in a single-neck round bottom flask, put in a stopper and heat with a bunsen burner.
Put everything in a beaker and heat it with a flame thrower from at least 5 feet away.
Put everything in a watch glass and touch a match to it; this will cause a "flambe" just like a burning dish in a fancy French restaurant.
Put everything into a 3-neck round bottom flask, put a reflux condenser in one neck, and a nitrogen inlet & outlet in the other two (or thermometer & stopper).
Pour everything into a coffee cup, put it in a microwave and heat on high till it boils.

5 You missed lunch, you're really hungry, so you run to the candy machines and grab a bar and a coke, then bring them back to the lab where you:
Eat them quickly outside the door, then rush back in to see your distillation blow up.
Put the food in a drawer below the hot water bath where you are doing viscosity.
Stand in front of the TA and gobble down your snack so he knows you're not breaking the rules.
Put the bar in your pocket and the coke inside your shirt so you can have a bite and a sip as needed.
Pour the coke into a beaker, cut the bar into small pieces on weigh paper and pretend they're both part of the reaction.

6 You have a whole bunch of acetone that you used to rinse your first polymer with. You take it:
To the waste bottle marked "organic waste: non-acidic, non-basic."
To the TA and ask him/her to get rid of it.
To the professor, and ask him where to put it.
To the drain where you pour it down with lots of water to flush it away.
To the hood where you let it evaporate in an open container.

7 You are working only with a water-soluble polymer, doing an intrinsic viscosity measurement in water. Since this is not dangerous, you:
Take off your safety glasses so you can see better.
Take off you glasses, but don't look at your neighbor who is diluting concentrated sulfuric acid by pouring water into it slowly.
Keep your safety glasses on, but raise them each time you need to watch the meniscus move.
Keep your safety glasses on, put on a face shield and put a bench-top shield in front of you.
Keep your glasses on and get used to always having them on no matter what you are doing.

8 You need to heat a mixture of monomers and catalyst to do a step-growth polymerization that takes a long time, so you:
Set up the reaction with a heating mantle, get it stabilized, then watch it while it reacts.
Put the reactants in a 3-neck round bottom flask with a condensor, thermometer and one open neck, then heat the reaction till it blows all the condensate out.
Put the reactants in a round-bottom with a magnetic stir bar, put it over a stirring hot-plate in an oil bath, turn the heat on and watch the temperature.
Put the reactants in a screw-cap bottle, screw the cap on and put it in the hood till next lab.
Put the reactants in your pocket and jump up and down while beating on your pocket with your hand.

9 You are doing a reaction that requires a salt-ice bath (like for making homemade ice cream, the salt gets it a lot colder), so you find an unlabeled bottle that looks like it has salt in it and you:
Dip your little finger in and taste it to make sure it really is salt.
Dip your little finger in and have one of your lab mates taste it to make sure it's salt.
Ask the TA if it's really salt.
Do a sodium burn test and look for a yellow flame.
Send it off for elemental analysis to a testing lab.

10 You are given a new monomer to try in one of the polymerizations. You should:
Trust the TA and the professor not to give you anything really dangerous since their job is to look after you.
Find some safety information, either in the safety book, on an MSDS sheet, over the web, or in the CRC Handbook.
Ask the TA if it's dangerous and what safety precautions you should follow.
Ask the professor during lab lecture what chemicals are safe.
Go to the departmental chairman and tell him/her that you aren't being given the safety information you need to do the lab, so you won't.
