The contents of riot control devices that are carried in vehicles in summer weather can reach temperatures as high as 150F. The purpose of this study was to determine if the irritancy of 1CR in propylene glycolwater increases when the solution is warm. Rabbits were dosed acutely by the intratracheal, ocular, and cutaneous routes and chronically by the ocular and cutaneous routes with heated and unheated 1CR in propylene glycolwater and propylene glycolwater alone, and the effects were noted. There were no differences in local toxicological effects of unheated and heated 1CR in propylene glycolwater 8020 and no signs of systemic toxicity in any of the animals. The data indicate no increases in the irritant properties of the heated solution.
