What is the shelf life of defensive sprays?

The shelf life of defensive sprays, such as pepper spray or similar products, is typically around five years. This period is important because it ensures that the active ingredients remain effective and the canister remains safe to use. Over time, the potency of the spray can diminish, and the pressurization within the canister may weaken, which can lead to reduced efficacy or even failure to deploy properly in a critical situation.

Using a product beyond its stated shelf life can result in situations where the user believes they have a reliable means of defense, only to find that the spray does not work as expected when needed. Therefore, the five-year shelf life is established to provide a good balance between safety and effectiveness, ensuring that users can rely on their defensive sprays in emergencies. Regularly checking the expiration date and replacing the spray as needed helps maintain a proper level of safety for individuals carrying these defensive tools.
