This is Nelson Hertz, our Senior Well Control Crew Chief. He is inspecting one of our big, (3000 lb) dry chemical units. These units are capable of putting out very large fires. Safety Boss has adapted and pioneered the use of these units replacing dangerous explosives as a means of extinguishing very large fires. This method is much safer and easier to use, on occasion they have been used to extinguish the fire several times in one day.
