Con-Tech sells drum plugs and provides information on how to use torques required for drum closures and plugs; in this case, what strength to use on the torque wrenches. This is the force that needs to be used by employees that close these drums plugs. If there is too much torque for closing drum plugs, they can be broken; the drum plug and gasket can get deformed and cause a leak. If there is too little torque on drum closures then they don’t close the plugs tight enough, and the drum can leak.
The DOT (Department of Transporation) has laws that require ALL manufacturers and reconditioners of drums (plants that clean used drums) to have these TORQUE requirements to avoid any accidents, especially those with contents that are toxic or flammable.
