This transformer used R-113 as the dielectric coolant and was very effective as a replacement for PCB units because of its relatively small footprint, non-flammable nature, and excellent performance. R-113 was a formEPA & OSHA Secondary Containment Requirements - Expert AdviceThe easiest/fastest is to put the day tank into a tank containment tub. This, of course, only works if you are able to lift the tank, and should be done when the tank is empty. If you want to build secondary containment around the day tank, the size of the system will be based upon the volume that the tank
