Abstract
Devices and method are disclosed for opening, e.g. by puncturing, sealed containers of materials, e.g. drums filled with toxic or hazardous substances. In one aspect a support cradle supports one or more containers and is movable to dump their contents into a discharge hopper. In one aspect containers are punctured or opened by movable spears or cutters which are movable to open the containers, preferably with personnel spaced apart from or remote from the apparatus during operation. A variety of spray devices or nozzles may be used to create fogs or protective fluid sheets or films over or about various parts of the apparatus to inhibit unwanted dispersion of material in the containers.
