Question of the Day – Tuesday November 7, 2017

Question:  What are the chemical constituents of “stage smoke or stage fog” and what adverse effects do some performers attribute to exposure to “stage smoke or stage fog”?

Answer: The cited article notes “Currently, mineral oil mists, glycols, and glycerin are among the most commonly used fog and haze materials…..Many performers have complained about respiratory health effects such as asthma and respiratory irritation from chemical stage fogs. Study results have been mixed about the occurrence of asthma but many of these materials are respiratory irritants that could exacerbate underlying asthma.” (Hinkamp D Et al.
