Bad Habits In The Lab
I wanted to start a thread talking about some bad habits that you have working in the lab. Anything that would not be proper (or safe) procedure
counts. I will start:
Swinging around glassware to get rid of extra water on newly washed things. For example, if I wash a graduated cylinder there will always be water
left in it, therefore I will swing it around and use centrifugal force to dry it faster. I am sure one day I will hit it on something and break it but
until then, I will continue the bad habit. ![;)](./images/smilies/wink.gif)

Haha, I'm guilty of that particular bad habit as well.
I also have the bad habit of letting the washing pile up until I have a mountain of glass to clean.

Too many to choose from........ probably the cider drinking while quietly doing things. I mean it's not like I get drunk and make explosives but yeah,
even drinking any liquid in a lab setting feels kinda wrong.
But whatever, it is my own lab, i'm going to play loud music and be awesome.
Edit: why do I sound like a rebellious 13 year old? At what point does the 'Adult' upgrade package get delivered?

I sometimes also leave my dirty glassware in the sink until I realise that I just ran out of clean 250ml beakers. Then i go into a washing spree and
get everything clean. Repeat.

They stopped the free upgrade decades ago. I think our grandparents received the last versions... ![:D](./images/smilies/biggrin.gif)
I'm just starting out in my lab but I noticed something last night. One of the first items to find a home on my work bench was an ashtray.
It also turned into one of the first items to be removed.

I just never put things back on shelves until I absolutely have to clear some space. I also often prepare and dry compounds before I have a place to
store them.

My only bad habit is smoking in the lab, obviously not while doing anything dangerous or around volatile solvents but smoking in the lab is a good way
to start a fire. Aside from the sometimes eating a snack in between things I dont have many "bad habits"
I think we are all experienced in nitric acid staining skin at least a little bit!

I generally leave flasks on a stirring plate without bothering to clamp them to anything. I realized this was a bad habit yesterday, when I came back
to find out that the vibrations had caused them to slide backwards off of the plates and break over the long weekend.

This actually used to be considered good lab practice for some when working for cyanides, if I recall correctly.

My biggest bad habit would have to be that I don't wear gloves all the time, unless I am handling toxic or corrosive substances.

By doing this at the basin I am washing up at, I have often smashed cheapo conical flasks on the faucet, so often that my significant other
drilled into my head the following procedure - "After turning off the water, turn faucet 90 degrees so that it is parallel with, and pushed against,
the wall said faucet is mounted on". In other words, it happened much too frequently.
Other bad habits include :
- Often using my face to move my nose to source of possible odor, rather than using my hands to move said odor to my nose.
- Opting to not use breathing apparatus for "odor-ific" procedures, in order to monitor and minimize possible impact to neighbors
- Not using gloves/glasses/coat/etc, with the rationalization being "It'll only be 30/60 seconds whilst I just 'have a look', nothing serious". Often
followed by dozens of hand washings or clothing changes across a dozen or so hours, just to "be safe"
- Carrying a cigarette in my hand or behind my ear unlit (I never carry a lighter in-lab for safety reasons) for as long as it takes for me to
accidentally snap/drop/wet it, usually resulting in two thirds of cigarettes in that lab session being wasted.
- Not shaving or wearing a hair net, resulting in a rare beard hair at the most inopportune moment.
- Failing to label non-volatile solids, or solutions of bicarb/vinegar/distilled water/brine/etc, resulting in wasted materials & time to replace
them due to being not fully sure when I had a need to certain of their nature.
- When buying labware having the mindset "I don't have one of those" instead of "This is what I need". Resulting in a lot of ornamental glassware,
reagents and equipment.
And finally, keeping any cracked/marred glassware, with the unrealistic belief of "I'll anneal/repair it one day". Pointless, due to the fact that I'd
never be able to "trust" said pieces again for anything at all anyway, because I'm not an experienced glass-worker.

I once heard a saying - "Real chemists wash their hands BEFORE going to the toilet". I'm glad I learned this one in the kitchen at an early age,
cooking up concentrated chilli sauce. I live by it in the lab, gloves worn or not.

Reminds me of a story that happened to a good friend of mine a year or two ago...
He's into mountain biking and was cleaning/etching parts of his bike with concentrated sodium hydroxide solution. No gloves, but it wasn't burning the
tough skin on his hands so he didn't really think about it. He went to the bathroom later on with that hydroxide solution still on his hands and,
well, recieved some rather unpleasant chemical burns on an area with more sensitive skin...
Being teenage guys we gave him a lot of shit for it, insisting he never went to the bathroom and they were in fact friction burns, but deep down we
all most certainly could sympathise with him and to this day I still definitely make sure I wash my hands before going to the bathroom

And yet, in the 30's to 50's, Hydrobromic Acid synthesis was done by teenagers in indoor labs whilst wearing the ol' tweed jacket and tie, with the
only safeguard against HBr escape is some excess H2O. Back when you had to rely on your skill with calculations rather than operating inventions, if
you will.
How the times have changed, eh? ![:P](./images/smilies/tongue.gif)

Letting the wash pile up is a big un. Though I'm kinda glad I did, or I'd have nothing planned in the lab tomorrow!. I also shake glassware really
hard to dry it. And I pick at stuck crystals with a glass rod, I've broken two stirring rods this way.

Got to excited telling my story and realized this wasnt actual an "accidents thread" sorry
I have the best accident story. Its a few years back in my second semester of organic chemistry. I cant recall what we were doing or what strength we
had but we had a test tube of some high molar NaOH solution. The lab called for putting something in the solution and shaking it to get agitation.
A few weeks prior to this I had gotten my first and only wart. It was directly on my thumb and it was very annoying and embarrassing, considering no
one I knew ever had one. I'm not stupid I know its not from doing some gross thing or a toad, I probably got it from gardening without gloves.
So anyway, I put my thumb over this test tube and shake it for a while. My lab partner says "that is extremely caustic you should use parafin film as
we were told" I stop clean off my hand and continue about the lab (acing it and winning the nobel prize of course) and in a few days the wart was
completely gone and never came back. I should add that solution ate a nice circle in my thumb and really did a number on the wart but it didnt bother
me.
Best outcome ever.

Haha, my teacher doesn't let us get near anything acidic over 3 molar.
Understandably, though; a few of the seniors in the class probably don't care enough to pay attention for the sake of their skin...

I must say you guys could get a prize if a contest of bad habits got created.
My worst habit is definitely stirring things up with thermometers. Whenever I'm running a reaction that requires a thermometer and agitation, I never
bother to get a stir rod. I just use the thermometer. I've broken two in the past few years with that habit ![:D](./images/smilies/biggrin.gif)
Also, I tend to only wear gloves on chemicals that are chronically toxic. That means no gloves when handling the common Triple Entente: Nitric,
Hydrochloric and Sulfuric.

wear em for concentrated H2O2 right?

I used to not wear gloves when using hydrochloric(used them for sulfuric and nitric though). One day I had a cut on my finger and spilled conc.
hydrochloric acid into it, damn does that hurt. Now I wear gloves using conc.
acids, though anything under 6M isn't worth it.
