ANSI E1.5 This video is a brief introduction into the fifth of ESTA’s American National Standards. The standard defines what chemicals can safely be in glycol and glycerin fogs, and it specifies the exposure limits for worker or performer safety. It also puts limits on any contaminants and decomposition products. The standard does not say that fogs made with other chemicals are unsafe, but, if they do not use the chemicals specified in this standard, they do not meet the requirements of the standard.
