It is important to understand the differences between the hazard types.

thank you! this is what I was looking for, the exsplaination was not that clear in the class, or I just remembered it wrong (I never do that ;)) But I did remember that the fish would be unable to breath :)

So... what happens if you get a cow wet? Or for that matter - drop a cow into a pond ?!?

OH THE HUMANITY! :eek:

I do know that milk if there is a accident with it it has to be kept out of the swewers and out of the watertable.

think how many cleaners are there that you can't mix?

clorine and ammonia this will react immdetly and can kill you.

there are other comon chemicals, that when mixed produces a gas that reacts with moisture and produces hydrocloeric acid, the is mositure under the arm legs inbetween, and lungs, and nasuial passageways. I wish I could remember the name of the gas :( I am trying to find more info on all of that too:) there are countless others like this, I mean neapaulm; thats a easy one to make; except when you make it yourself its not as stable :eek:

Your talking about when the bleach and ammonia mix it produces Chlorine gas. The excess Cl- bonds together to for Cl2. That reacts with water producing HCl. ((2) Cl2 + (2) H2O --> (4) HCL + O2). The common name is mustard gas. After the reaction is complete the HCl with dissolve in water leaving H+ and CL- as free radicals. These tend to react violently with organic tissue.

Thats what I was thinking the name is, but I didn't want to post it till I knew I was right, a foot can only go in a mouth so many times in one thread. do you remember the chemical name of mastard gas?

It is simply Chlorine Gas.

I didn't think I was going to need my chemist's hat in this thread. Mustard gas is dichloroethyl sulphide. Like chlorine, it was used in World War 1. A short article on WW1 gases is available here.

Ah... I was under the impression the they used Cl2 gas also. Oh well, learned something.
