Hazard evaluation of infrared smoke grenades based on the dispersion and the composition of the smoke.

Abstract

Analysis of PAHs and dioxins in smoke from 155 mm smoke canisters and 76 mm smoke grenades show that the generation of carcinogenic PAHs is 644 μg/g soot, and 66.2 pg/g soot for dioxins. At 100 m from the smoke source of 155 mm canister, the exposure to carcinogenic PAHs is equivalent to smoking less than two cigarettes. At 20 m from the smoke screen of 76 mm grenade, the exposure is equivalent to smoking three cigaretes.
