Review on BENCHMARK FR Flame Resistant Face by Bruce Marable

Nothing to see here. These single ply "mouth and nose plugs" are single ply and daylight can be seen through them. It is not safe for your surrounding employees or the public. Another product with a false sense of security is very expensive t-shirt materials that are printed on it to make it look important. It's important to remember that it's the layering that matters, not the properties of gauze.
