Scary Toxic fumes. From What?!

I have an old 15 gallon plastic fermentor pale that I keep my small equpment in. The only chemicals in it are some sulphites and iodophor. They are 100% sealed up in their containers. Other that that I have tubing and cappers and airlock etc.
So today I opened it up and a waft of strong fumes filled my sinuses and smelled very sour and made my throat and nos burn like hell. Now I keep coughing up green mucus and my stomach really hurts. Im on my way to a doctor soon but does anybody have a clue what those fumes could have been from? I took everything out and its all clean and nothing has spilled. Im quite worried aboout this.

Sulphite compounds + iodine can form sulphuric acid, but that usually happens in aqueous solution.

Hope your doctor figures out your trouble quickly and you suffer no ill effects. Good luck!

The vapor of iodine is very irritant to the broncho-pulmonary mucous membrane, causing cough, spasm of the glottis, and increased flow of mucus.

That was a quick Google search but it sounds like iodine vapor is the culprit. Are there any warnings on Iodophor? I don't have any.
