Abstract:
1. A method of evacuating pressurized gasses from a drum to a safe location prior to dispensing liquids therefrom, comprising: providing a fluid containment drum having an access opening into an interior of the drum; providing a drum insert to the fluid containment drum at the access opening, the drum insert including a downtube extending proximate the bottom of the drum, the downtube providing an upwardly extending nipple for connection of a fluid dispense head; the fluid containment drum having a fluid therein capable of producing pressurized gas above the fluid in the fluid containment drum; providing a drum cap to operably engage the access opening of the drum, the drum cap including a rotatable valve member with an open and closed positions, the valve member further including a rotatable valve conduit extending therethrough positioned to be in flow communication with the pressurized gas at the top of the fluid containment drum, the drum; shipping the fluid containment drum from a first location to a second location with the valve member in a closed position; providing a venting member at the second location, the venting member adapted to operably engage the drum cap and having a venting tube extending therefrom; operably engaging the venting member with the drum cap, such that the venting tube is in operable engagement with the rotatable valve member, wherein operably enagaging the venting member with the drum cap includes engaging at least one corresponding engagement portion of the rotatable valve member; opening the rotatable valve member of the drum cap such that a continuous gas passageway is opened from the pressurized gas in the interior of the drum, through the valve conduit, and out through the venting tube; and at said second location, evacuating the pressurized gas from the interior of the drum through the gas passageway to a safe location displaced from the access opening; after the pressurized gas has been released, removing the drum cap; and installing a dispense head onto the drum connecting to the nipple for dispensing fluid from the drum.
