Abstract

This report documents a preliminary investigation of the measurement of droplet sizes in the spray from four commercial fogger type pepper spray products. Droplet sizes were detected over the range of 2 mm to 120 mm by phase Doppler interferometry at a distance from the canisters similar to that expected when the spray is used as a defensive weapon.
