Hugh Hoagland and his team from e-Hazard went to Louisville Processing and Cold Storage to conduct a series of experiments on anti-fogging technologies in face shields. The experiments were conducted in the facility's Cold Room, a controlled environment of -13 degrees Fahrenheit (-25 Celsius). The experiments shown in this May 2016 video were a simulation of workers using Personal Protective Equipment for arc flash protection in an extreme cold work environment. http://e-hazard.com
