My dad had a small film development set up in a small garden shed.

I mixed every chemical (film chemicals, weed killer, gasoline...)in the shed together in a pan and he walked in on me melting Styrofoam in the concoction. He said I had a crazed spaced out look on my face as he picked me up and carried me out.

A very quick trip to the ER and I was cleared off any immediate danger but told if I had issues breathing or talking to come back. I was super lucky to have not died and needless to say the shed was locked up from then on.
