Is Pepper Spray Flammable?

Quick Answer: Can Pepper Spray Catch Fire?

Most modern pepper sprays, including those sold at TBOTECH, are non-flammable because they use water-based or other non-combustible carriers. However, some older or specialty formulas containing alcohol or volatile solvents can ignite if exposed to an open flame.

Understanding which formulas are safe and how heat impacts pepper spray canisters is critical for safe use. Let’s break it down.

What Makes Pepper Spray Flammable?

Pepper spray is primarily composed of oleoresin capsicum (OC)—a spicy extract from chili peppers. While capsaicin itself is non-flammable, the carrier solution used to disperse it determines whether the spray can ignite.

The Role of Carrier Solutions

Carrier liquids are used to dilute capsaicin and allow it to be sprayed effectively. These carriers affect flammability:

• Water-based sprays → Non-flammable and safest for all environments ✅

• Alcohol-based sprays → Flammable and may ignite if exposed to flames ❌

• Oil-based or aerosol sprays → May contain flammable propellants ❌

Are All Pepper Sprays Non-Flammable?

No. Some older or specialized law enforcement sprays may contain flammable solvents. Always check the product label before purchasing.

Can Pepper Spray Ignite Near an Open Flame?

If a flammable carrier like alcohol is used, then yes, the spray can ignite if exposed to fire or sparks.

Real-World Fire Risk Scenarios

• Scenario 1: Using an alcohol-based pepper spray near an open flame? → High fire risk

• Scenario 2: Using a water-based pepper spray in a heated environment? Safe ✅

• Scenario 3: Storing pepper spray in a car during extreme heat? Not flammable, but may explode

Does Heat Affect Pepper Spray? (Explaining Pressure Risks)

Even if your pepper spray is non-flammable, exposure to high temperatures can cause pressure buildup inside the canister.

Heat Exposure Risks:

• Left in a hot car? → Can cause leakage or even bursting

• Stored near radiators or direct sunlight? → Pressure increases, risking an accidental discharge ❌

• Freezing temperatures? → Some sprays may lose effectiveness ❄️

Storage Tip: Keep pepper spray at room temperature and avoid extreme heat or cold.

Is Pepper Gel Safer Than Aerosol Spray?

Yes. Pepper gel is a newer, safer alternative to aerosol sprays. Unlike traditional pepper spray, pepper gel does not disperse in the air, reducing the risk of accidental inhalation or ignition.
