Self-Defense Spray
Self-defense sprays such as mace and pepper sprays contain the ingredient Oleoresin Capsicum. While this material is not life-threatening to humans or hazardous to the environment, it causes severe eye, nose and skin irritation. In addition, self-defense spray is made in pressurized aerosol canisters. Self-defense sprays can be disposed in the regular trash, but always bag them tightly to prevent leakage or accidental discharge.
