Ever since 1974, when the first Oleoresin Capsicum (OC) product specifically developed for law enforcement began to get marketed and sold out of a garage in a south Florida home, Aerosol weapons have become increasingly popular. Unfortunately, outside of a short course taught at the basic academy, little exists for most agencies in the way of advanced OC training, and a multitude of myths about what OC is, how it works, and what it's capabilities and limitations are have risen over the last 3 decades. Like all defense tools, the proper use of OC requires training. This article represents no replacement for that formal training, but is written only in hopes of dispelling some of the most common myths and misconceptions regarding OC and its proper use.
