The BIP CS Tear Gas Powder Round combines blunt trauma with the effects of a micro pulverized irritant powder to maximize pain compliance. The round has become very popular due to its strong effect and lack of toxicity. The chemical reacts with moisture on the skin and in the eyes, causing a burning sensation and the immediate shutting of the eyes. Effects usually include tears, profuse coughing, exceptional nasal discharge,burning in the eyes, eyelids, nose and throat areas, disorientation, dizziness and restricted breathing. All of the SDI family of BIP products are based around a patented collapsible head technology which acts as a riot deterrent, a crowd-control medium, and an alternative to lethal force in critical situations that demand less-lethal solutions. Using SDI’s innovative technologies, the BIP CS was designed for operational effectiveness at distances of up to 80 m (262 feet), while still enhancing target safety if engaged from close range–even as close as 2 m (6.5 feet). Due to its internal energy absorption system and collapsible nose (“mushroom effect”), the advanced engineering of the BIP CS enables the projectile to engage the target with maximum pain compliance while deploying CS Tactical Powder.
