Pepper spray has proven to be an effective tool in preventing an attack. The irritation is so bad that the eyes swell up and close shut, rendering the attacker temporarily blind. Mini pepper spray key chain can make the skin and mucous membranes in the nose and throat so irritated to induce coughing and choking.

However, there are important limitations when using pepper spray. First, pepper spray works best when sprayed right side up. Second, if there is too much wind it is not recommended for use, especially if the wind is blowing against you because you might get sprayed on. The best kind of pepper spray you can get is foam type. Foam pepper spray is so thick and sticky that it saturates the attacker's face even in windy conditions.

Pepper spray is also available in streams, gels, foggers and aerosols. Some pepper sprays are also loaded with tear gas. Most pepper sprays come with an identifying UV dye to help police pinpoint an attacker and present evidence in the crime.

Pepper sprays come in many shapes and sizes. Mini pepper spray key chain in injection molded or leatherette holsters, 1-pound canisters with pistol grip, baton pepper spray, pepper spray guns, and pepper spray disguised as a lipstick, pen, pager, or ring are all effective in stopping an attack.
