What systems are typically used today to dispense hazardous chemicals from drums?
Common methods today include different versions of an open system, in which chemicals are either poured or pumped out of the drum. In semi-closed dispensing systems, a dip-tube draws chemicals from vertically oriented containers using an attachable hand or electronic pump. While a step in the right direction, the dip-tube is reused from one drum to the next, exposing the end-user to drips, leaks and fumes during transfer.
