Even though you may be purchasing a drum that meets the United Nations criteria for shipping hazardous materials, the proper closure of the drum is the final and most important part of the regulation. So much so, that the US Code of Federal Regulations requires that packaging manufacturers give written instruction to the fillers about the proper closure procedure. For closed head drums, this would reference torque required when sealing the plugs, and for open head drums, it is a combination of closure torque and ring gap distance. While every Skolnik order includes closure instructions, call us to receive an additional instruction sheet for your record keeping.
