Abstract
Abstract A safety gas and liquid containment unit is provided with sealing for retaining the hazardous gas therein until treated. The containment unit can be placed on a transport carrier and rotated from a vertical position to a horizontal position thereon. The gas cylinder may be brought to the containment unit by placing it on a wheeled cart. By aligning the cart with the horizontally positioned containment unit, the container is then transferred from the cart to the containment unit, which can in turn be transported to an appropriate area for treatment. Upon removal of the toxic or other gases, the container can be withdrawn from the containment unit by a winch mechanism.
