Abstract

Commercial pepper sprays devices deliver a coherent liquid stream or an aerosol from a pressurized canister. It is likely that some of the droplets from the aerosol-type pepper sprays inhaled during its use to assist in subduing individuals resisting arrest. Since smaller particles can penetrate deeper into the lung and may present a greater health risk, it is important to know the diameter of the particles expelled aerosol droplets. This investigation used laser Phase Doppler Inferometry (PDI) to measure the droplet size distributions of four different sets of commercially available canisters.
