Protip: the capsicum in pepper spray is suspended in oil. Oil floats on water. Water can be found, for instance, in toilets. Toilets, when flushed, actually fill the surrounding area with a fine mist due to the turbulence created. I won't elaborate farther.
You are correct about the toilet aerosol. That is why you should ALWAYS flush the toilet with the lid closed. It confines the aerosol to a much smaller area, mainly, the floor around the commode.
Pepper spray lasts a lot longer. Plus no one tells you about the part where it stays in your hair and reactivates when you shower. But, overall being tazed felt much worse to me. And mind you I did not take the pepper spray like a champ:
One time I walked into a confinement dorm where I was working. I did my usual stuff and pored myself some coffee. Then I went to the bathroom and took a piss. About 5 minutes later my penor felt like it was going to burn off! After a little investigation we figured out that the shift before mine, they had gassed an inmate and the officer who did it didn't wipe the gas off his hand before poring himself some coffee. When I looked at the handle on the pot, I could see the little orange streaks from the gas that was still on there!
Burning penor is no way to start a shift.
Another protip: contact lenses contain a lot of water. When you spray someone the mist gets into the lenses. When you take those off and put them in the case the saline reactivates the gas. When you put the lenses back in, burning face!
The secret sauce for removing oleoresin capsicum from in and around the eyes is baby shampoo.
When I use to whole sale ASP products we had a vendor accidentally set off the pepper spray in this tiny little conference room. Needles to say it was not a pleasant meeting.
When I was in college I bought a girlfriend some pepper spray. I told her she was to take it outside and test-fire it, and do it once every two weeks or whatever it said on the label. She didn't want to, so I took it outside and did it myself.
An hour or so later, we had been making out a little and were about to take it a little further... until I touched her hoo-ha. I had neglected to wash my hands. That sort of killed the mood.
This is a true story.
Another protip: Paint thinner can cause you to burn as well. Have an annoying spouse who won't stop snoring? Shoot her in the fucking head.
