The automatic treatment installation comprises: at least one basin filled with water for submersion of the containers; means for the automatic conveyance and subsequent submersion of the baskets carrying waste containers; explosion means (explosive fuses and detonators); these means being integrated into a whole complex comprising: an area for the loading of the baskets; a room for the storage of explosives and a room for the storage of the detonators, with safety areas; and a system for the recovery of the broken containers. This method and installation can be applied to the destruction of wastes and products from all laboratories chemicals facilities. ## Claims ### Claim 1 An apparatus for destroying containers containing wastes comprising: (a) at least one basin or pool filled with water to a depth of at least two meters; (b) means for automatically conveying and submerging containers of wastes into the water of said basin; and (c) means, associated with said means for conveying and submerging, for bringing about the explosion to destroy the containers at a predetermined instant. ### Claim 2 (depends on 4) An apparatus for destroying containers containing wastes as recited in claim 4, wherein means for bringing about the explosion is comprised of continuous explosive fuses positioned between rows of containers, and a detonator positioned on a fuse. ### Claim 3 (depends on 2) An apparatus for destroying containers containing wastes as recited in claim 2, further comprising: an area for loading said means for conveying and submerging; a room for storing said explosive fuses; a room for storing said detonators; safety areas for said rooms; and means for recovering broken containers. ### Claim 4 An apparatus for destroying containers containing wastes comprising: at least one basin or pool filled with water to a depth of at least two meters, said basin or pool comprising a first vessel of corrosion-resistant material, having an inner and an outer peripheral wall, being filled with the water and mounted on a damping means within a second vessel made of concrete or similar material; means for automatically conveying and submerging flasks or similar containers of wastes into the water of said basin; and means, associated with said means for conveying and submerging, for initiating an explosion at a predetermined point in time. ### Claim 5 (depends on 4) An apparatus as recited in claim 4, wherein: said inner peripheral wall of said first vessel is provided with a perforated conduit where gases generated within the water are drawn in and recycled to the bottom of said first vessel creating a rising current of bubbles; and said outer peripheral wall of said first vessel is attached to a means for protecting against splashing liquids. ### Claim 6 An apparatus for destroying containers containing wastes, comprising: at least one basin or pool filled with water to a depth of at least two meters; means for automatically conveying and submerging flasks or similar containers of wastes into the water of said basin, wherein said means for conveying and submerging flasks or similar containers having baskets with fine metal grating and having the flasks for containers arranged in at least two concentric rows in a circular or elliptical configuration, and wherein said baskets are conveyed to said basin by an automated conveyance rail; and means, associated with said means for conveying and submerging, for initiating an explosion at a predetermined point in time. ### Claim 7 A method for destroying containers containing wastes, comprising the steps of: conveying a basket made of fine metal grating and carrying containers arranged in rows and having toxic wastes therewithin; providing detonating fuses interposed between said rows of containers; thereafter submerging said basket in a water-filled basin followed by exploding said detonating fuses; lifting said basket and washing said basket; and collecting and diluting the wastes released upon the destruction of said flasks or similar containers in said water-filled basin for periodic removal. ### Claim 8 (depends on 7) A method for destroying containers containing wastes as recited in claim 7, wherein the step of providing detonating fuses comprises selecting explosive fuses and associated detonators capable of withstanding submersion in water for least one minute. ### Claim 9 (depends on 7) A method for destroying containers containing wastes as recited in claim 7, wherein the step of submerging said basket in a water-filled basin comprises submerging said basket in water to a depth of at least one meter.
