Obscurants containing glycols and glycerin, which are widely used in the entertainment industry to produce theatrical effects, are now being used in more concentrated forms in antitheft and riot control. While there have been several studies demonstrating that theatrical fogs are innocuous for humans, the toxicity of the denser fogs has not been examined. In this paper we review the results of previous safety studies of theatrical fog, summarize the effect of increasing concentrations of these obscurants on visibility, and then report on the physiological and biochemical impact of higher concentrations of these obscurants for several hours in rats. Our results suggest that even prolonged exposure to highly obscurant levels of propylene glycol / glycerin fog produces only minimal physiological aftereffects.
