Its amazing how much a burn ward costs a day. I was holding the visonware dish of naptha, which was boiling very furiously, moving it off the hotplate, and when I moved it out of the flow of air from the fan that was keeping the fumes from settling and accumulating, it ignited in my hand. Stupid move, moving it all when it was boiling that much. I've had naptha flash before, and it was always easy to control. This time it was flaming and rolling over the sides of the dish and over my hand. I jerked, got flaming naptha on my chest, realized the wet towel was all the way over there and the sand was all the way over there and that fire extinquisher I was so proud of was under there and I had to make a decision really really quick.

Anytime you become accustomed to doing something you become casual about the inherent risk in doing what you are doing. I did, was stupid at the wrong moment, and paid for it. When I dropped and rolled to get the flames out, I knocked a lens out of my glasses. The shirt reignited as I tried to pull it off, and I had to drop and roll again. Once I got the flames on my chest out I had no trouble getting the situation controlled. I had the wet towel, the sand, and a fire extinguisher on hand. The bitch was driving the fifteen miles to the hospital at night without glasses and with skin dripping off the hand I was holding out in the night air. I could see exposed bone in two fingers.

The skin grew back, and I survived without any disability from the excitement.

That was the worst fuck up I've had thus far.

I recall an evening when I had some serious flatulence and the lab was becoming a noxious place to be. Ever resouceful I lit a scented candle, which did such a wonderful job I moved it to the bench. Which is where it was still burning, overlooked, as I tossed that fifty ml of acetone in that evap dish right next to it....

Neat job of removing eyebrows.

LOL the way it started I thought you where gonna go into the cartoon realm there geez  like ya see on TV. Someone got to much gass and they blow up a room

I just recently spilled a test tube with HCl on my leg... thinking quickly I rubbed a shitload of sodium bicarb on it and it wasn't bad other then bleached pants.

I learned yesterday that you should never make more bromine that you need for a reaction.

I made about 200ml of Br2 and it wasn't a good idea....the smell 

It was the first time I attempted making bromine from a bromide salt, (~85%)con. H2S04, and 35% H2O2.

It proceeded in pretty much the same way as sodium hypochlorite, bromide, and HCl with a few differences.

Sodium hypochlorite+ NaBr = yellow solution(no fumes) [+HCl = red solution(red-brown fumes)
H2SO4+ NaBr = orange solution(white fumes) [+H2O2 = red solution(red-brown fumes)

I guess the H2SO4 partially oxidized some of the salt, hence the orange. I still couldn't get any Br2 to precipitate. Every time since I would only get a red solution but never a bottom Br2 phase.

I've never been burned by HCl, does it actually burn certain people?  Is this the 37% or 31.45%.  I've had the 31.45% dump on my hands before.  The worst it does is sting open wounds, and if left on for 20-30 seconds, it'll start to itch, followed by some irritation, but that's about it.  27% H2O2 hurts much worse IMO.  Some people may be different though.

In order to get a bad burn it must rest on the skin for a little bit such as a drop you didn't know you had that picks up pace a minute later and starts to burn. It was typical muratic and it didn't really cause much of a problem other then fuckin up my clothing. I must agree that the 35%H2O2 I got hurts ALOT more then muratic acid or even H2SO4 for that matter. It seems to have a way of getting into your pours and making it burn like no tommorow. Simular to a bunch of little pins and needles all over the exposed area.

hmmm geezmister's disaster sounds pretty bad.

once a champange bottle was filled with reactants and it was taken  out of the bath with the contents under pressure.
it air cooled and exploded everywhere spraying good product all over the walls cut me to shit.
it was nasty.
learned a lesson from that too.

oh and geez do'nt heat flammable chemicals directly on a hotplate any spills and it will flash and your crispier.
always use the sand bath.

and the scare for the rest of your life..
Well at least mine seem to stay... Its nice.

Wow be very careful!
EDTA time? 

EDTA is a chelating agent.. might help with Hg poisoning.. I dunno
Milk, eggs, and a few other foods also help as they have substances that act as chelating agents in them as well...

Oh okay got ya! I'm not too worried about it. I wasn't exposed for very long. Got all my windows open and air circulating through quick. What should I look for for mercury poisoning just in case?
