Defense Sprays (e.g., Pepper Spray, Tear Gas, etc.)
Defense sprays are chemical sprays that incapacitate an assailant via irritant or inflammatory effect. The sprays that most sites offer mainly rely on an extract of hot pepper plants for their effectiveness. This extract is called Oleoresin Capsicum (OC). OC is an inflammatory agent that has an instantaneous effect when sprayed into the eyes and face of an assailant.
The heat from pepper extracts is measured in Scoville Heat Units. The typical jalapeno pepper rates at about 2,500 Scoville Heat Units, while the some commercially available sprays rate at up to 2 million Scoville Heat Units. So, to get an idea of the effect of getting sprayed, just think about the last time you rubbed your eyes after handling a jalapeno pepper, and multiply that feeling by about eight hundred times!
Range of these sprays is usually several feet and the effects take 20-30 minutes to wear off with no long-term ill effects to the assailant.
If you do decide to purchase a defense spray, make sure you get a good, quality brand like Mace, and that you replace it every six months to ensure your spray will work when you need it.
Be advised, however:
- Several feet is NOT a large distance. Any attacker coming at you already will likely close that distance despite being sprayed, and once you are within reach, it is likely some damage will come to you. It is possible you will escape unharmed, and it is also quite possible you will be severely injured or killed.
- For an assault that occurs at very close range — as many assaults do — you will be unable to spray your assailant without getting hit by the spray yourself. In the worst of cases, you spray yourself blind and your assailant is largely unaffected, leaving you pretty much helpless.
- The effect on an assailant is somewhat dependent on the assailant. Some folks have a natural resistance to defense sprays. Some people are on drugs which don’t allow them to register pain fast enough or severely enough to change their vector.
- The legality of defense sprays is regulated at a state level and your state may have specific rules about when you can deploy, what kind of sprays are legal, and what the contents of the sprays may contain. Check with your local legal sources before purchasing, especially if you go online.
- Like any weapon, a defense spray can be turned against you. You should treat this like any other weapon and commit to training and practicing drawing and using it.
