Yes Mercury is very dangerous to inhale! and Bromine can hurt your lungs and make them swell to make breathing hard. I assume you are better now? I hope you are.

When I was younger, I made a dangerous thing. I use S2Cl2 that I made from sulphur and Chlorine generator. I purified the S2Cl2 until I was certain of its purity and its nearly low water content from vacuum fractional distillation. Everything was exact. I spent nearly one month to do this, almost every day when I could until complete. To me it must be perfect then.

I used the S2Cl2 to produce a small amount of Sulphur Mustard as it is called from a glycol that I will not say. I then sealed it in an ampoule, which I washed with bleach and acids and bases and even water. One after one until clean on the outside.

The ampoule only totals 5 millilitres of Sulphur Mustard and the rest is nitrogen gas. It is the most difficult synthesis I have done because of danger if you make a mistake. I don't have the ampoule any more because I put it in a box I made to survive in the ground until I want to look at it. I think today I would get in permanent trouble if I had it with me so I keep it safe in the ground in the box I made.

I only did it to see if I could. I am lucky I did not die because I was younger then.

Its between H2Se, or white phosphorus, a very small burn, around the size of a lentil caused by WP on my arm, caused it to become weak and shaky for quite some time, a week or two if I remember right, it was quite a while ago, but after that I could barely hold a pencil to write with until a couple of weeks had passed. I can only attribute it to that small fleck of WP that I managed to get burned by, as I wasn't working with anything else particularly nasty at the time.

Chloroacetone and acrolein also, I don't know about particularly deadly, but they have to be honourably mentioned as some of the most obnoxious things I have worked with, you don't know what 'fast' means, until you see somebody's feet moving after they were just in a garage working on something that involved a load of chloroacetone that decided to flash boil, and make like a volcano.

 

h2s is nasty shit...

potassium cyanide is shitty too, but it smells a lot nicer than h2s. you get a nice whiff of almonds and cherries right before you die.

white phosphorus sucks too. you ever try to get that shit off your fingers? ooo boy!

and your burps dont smell like cherries to bad!

im not even going to tell you my potassium ferrocyanide story...

if youve burped it too, then we should start some 'fight club' style chem club.

'i want you to drink the liquid... drink the liquid as fast as you can'

The United States standard cyanide antidote kit first uses a small inhaled dose of amyl nitrite, followed by intravenous sodium nitrite, followed by intravenous sodium thiosulfate.  Hydroxycobalamin is newly approved in the US and is available in Cyanokit antidote kits.  Alternative methods of treating cyanide intoxication are used in other countries.

The International Programme on Chemical Safety issued a survey (IPCS/CEC Evaluation of Antidotes Series) that lists the following antidotal agents and their effects: Oxygen, sodium thiosulfate, amyl nitrite, sodium nitrite, 4-dimethylaminophenol, hydroxocobalamin, and dicobalt edetate ('Kelocyanor'), as well as several others . Other commonly-recommended antidotes are 'solutions A and B' (a solution of ferrous sulfate in aqueous citric acid, and aqueous sodium carbonate) and amyl nitrite.

The UK Health and Safety Executive (HSE) has recommended against the use of solutions A and B because of their limited shelf life, potential to cause iron poisoning, and limited applicability (effective only in cases of cyanide ingestion, whereas the main modes of poisoning are inhalation and skin contact). The HSE has also questioned the usefulness of amyl nitrite due to storage/availability problems, risk of abuse, and lack of evidence of significant benefits. It also states that the availability of Kelocyanor at the workplace may mislead doctors into treating a patient for cyanide poisoning when this is an erroneous diagnosis. The HSE no longer recommends a particular cyanide antidote. Qualified UK first aiders are now only permitted to apply oxygen therapy using a bag valve mask, providing they have been trained in its usage.

I kinda like H2S smell,can-t explain why though...
Since 99% of people hate it,it is good to have vial of ammonium sulfide arround
if you don-t want anyone sticking nose where it doesn-t belong! 
I have been exposed to the mercury and uranium salts,I2 vapours,
p-benozquinone(your skin darkens upon exposure and than fals of after day or to,but it doesn't hurt)

Other than that:cianides(they smell realy nice!To bad they are poisonous!),
formic acid,some organophosphates...

Worst thing I ever been exposed to and I dont know what the hell it was. I assumed CO2 evolution but the rapid effects I got from inhaling the off gas where no doubt NOT CO2. I had a rapid heart beat and dizzy head ect...

Alot of the effects could have been placebo but im pretty damn sure that they where not because after getting clear headed I repeated it and it indeed had the same effect. I have heard CO2 causing panic attacks but i think this is something different. If not CO2 is scary shit.

Wish I remember what it was but it was sometime ago .

I thought CO2 was inert like argon or helium? It may combine forgive my ignorance if it does. I know for fact CO2 displaces oxygen and while its not toxic when you breathe it you aren't getting any oxygen no matter how hard you breathe. In a pipe fabrication shop I knew of a man that acciendently dropped his paycheck into a the opening of a stainless steel pipe header. He crawled into retrieve it and when everyone came back from lunch he was dead from asphyxiation. The pipe was full of argon and could not support life. Thats why they are so strict on confined spaces.


Off topic I understand where Tsathoggua might be coming from. My brother left the Hilton where the twin towers were about a hour before the first plane hit. He got as far as Atlanta and they put all the planes down. I am thankful that I am not bitter but I would be. At the same time I agree with QD, not only is this an intellectual forum, its an elite intellectual forum. Lets stay on synthesis, pharmacology and above all chemistry.

I have heard that pure CO₂ behaves simular to LSD and CO₂ causes panic attacks making scientist rethink the pathways it causes hallucinations. I kind of doubt it and wish I had a good source but I dont. However im pretty convinced whatever was comming out of that flask that day was not CO₂ because I was in bad shape. It had no real smell but one whiff and I was fucked.

Well CO₂ is easy enough to make so perhaps one day I will test this but I highly doubt it was CO₂ I was breathing in.

Fast Food.  


(Go) Fast Food probably would of been ok though.
