This is a warning not a "how to". Really!
This is the story of one of my biggest foul ups ever.
I dehydrated and smoked ALOT of Jalapeno and Habenero peppers one year.
I then turned the jalapeno into powder in my Vitamix blender and put the warm powder into 6 ounce mason jars. When they cooled it pulled a seal.
Next I powdered the Habeneros. Dang near killed me! Stopped the process and moved it outside to finish. The fumes from the sealed Vitamix took me out! I have been sprayed with the Fox and Saber and it does not hold a candle to this pure powder. It was not anything I could "fight through".
It turned my skin a very bright red like a sunburn for 2 days. I had to strip down in the yard and hose myself off with dawn detergent multiple times. The clothes went into the trash.
When I make a big pot of chili and I want it HOT I add 1 teaspoon of the powdered Jalapeno pepper powder for heat. I like hot food alot but this stuff has turned mutant! I have a case of the powdered Habenro and I have not even opened a jar yet as I have been working on the first jar of jalapeno powder for 3 years now. Boy it sure does have a fine taste though as I roasted them dry in the oven first.
I gave a jar of the Habenro to my buddy and he opened it in his kitchen and his wife made him bring it back to me.
I would think if you took a large dry chemical fire extinquisher and added a half cup of Habenero to 20 pounds of dry chemical powder and charged it up then you would have a real crowd control tool to make folks move on. If used inside you might have to get a hazmat team to do the cleanup.
I guess you could heat it in hot oil and do a oil extraction but that is just a insane guess. I will not ever try it EVER. It is dangerous!
To this day the vitamix stainless steel blender jar still has the aroma after multiple cleanings. After it was found out what I did I had to buy another Vitamix mixer to keep peace in the house.
Here is pepper Scoville Unit info
http://homecooking.about.com/library/weekly/blhotchiles.htm
Peppers are rated based on Scoville Units, a method developed by Wilbur Scoville in 1912. The original method used human tasters to evaluate how many parts of sugar water it takes to neutralize the heat. Nowadays human tasters are spared and a new process called HPLC, or High Performance Liquid Chromotography measures the amount of capsaicinoids (capsaicin) in parts per million. Capsaicin is the compound that gives chiles their heat.
Jalapeno peppers 2,500 - 5,000 Scoville Units
Habanero peppers 350,000 - 855,000 Scoville Units
