What is Pepper Spray?

Pepper spray, also known as oleoresin capsicum spray or OC spray, is a popular self-defense tool used around the world.


Pepper spray is a lachrymatory agent, meaning it stimulates the eyes to produce tears. It is used as a non-lethal means of defense and for crowd control. It is designed to cause discomfort and temporary blindness to allow a person time to escape a potential threat.


The main ingredient in pepper spray is capsicum, a naturally occurring substance found in chili peppers that produces a burning sensation. This capsicum is often mixed with a propellant, which allows the spray to be shot out from the canister with some force.


While originally used by law enforcement for crowd control, it has, over the years, become a common household self-defence item. It’s very popular among women, travelers, and anyone who feels they might be at risk of personal attack. It is also used by postal carriers as a defense against aggressive dogs.

Effects on the Eyes

One of the primary targets when using pepper spray is the attacker’s eyes.

Immediate effects

On coming into contact with the eyes, the active component of the spray causes intense burning pain, forcing the eyes to involuntarily shut due to excessive tear production and inflammation. This temporary blindness lasts for about 15-30 minutes, depending on the strength of the spray.

Long-term effects

Long-term effects of pepper spray are generally uncommon, but they can occur. Occasional side effects include corneal abrasions, allergic reactions, and, in rare cases, more severe problems like glaucoma.


After exposure to pepper spray, it’s crucial to immediately flush the affected eyes with water or a saline solution to minimize pain and potential long-term effects. Medical consultation should be sought if discomfort persists.

Choosing the Right Pepper Spray

Choosing the right pepper spray can be crucial in ensuring your own safety.


The most common types of Pepper sprays are fogger, stream, gel, and foam. Foams and gels have longer ranges and stick to the attacker’s face, while foggers and streams can affect multiple attackers but carry the risk of blowback.

Legal considerations

While pepper spray is legal in most parts of the world, some places have restrictions such as age limits, carrying permits, or size limitations. It’s best to check local laws before purchasing.

Brands to consider

Some reputable brands to consider include Sabre, Mace, and Pepper Shot. These brands are known for their quality and have options suitable for different needs and preferences.

Proper Usage of Pepper Spray

Knowing how to properly use pepper spray can make all the difference in an emergency.

Keeping distance

Typically, pepper spray can be used effectively from a distance of 3-10 feet. Keeping an adequate distance from the attacker helps keep you safe while ensuring the pepper spray is effective.

Aiming for the eyes

To maximize the spray’s effectiveness, aim for the attacker’s face, particularly the eyes. The spray causes temporary blindness, giving you time to escape.

Spray techniques

Using short bursts of spray can be more effective and easier to aim than a continuous spray. It also allows conserving the spray for multiple uses if needed.
