This invention relates to methods for discharging particulate solids, especially hazardous or toxic materials and contaminants of the atmosphere, from bulk shipping containers, such as bulk-bags, at controlled discharge rates, in an environmentally acceptable manner which eliminates exposure of the environment and personnel to contamination by the material and which allows for an essentially clinically clean environment due to emptying and transfer of the contents to process equipment.

The method for discharging particulate matter such as dry solids from flexible wall bulk-bag shipping containers which comprises: inserting the unopened bulk-bag containing the particulate matter to be discharged into a disposable envelope, placing the bulk-bag so enveloped into a vertically positioned drum and securing the bulk-bag and envelope to the drum, fastening the drum containing the enveloped bulk-bag to a vertically positioned dolly which is attached to a frame capable of (a) being tilted through a 180 degree angle (b) horizontal-lateral movement and (c) 360 degree rotation, tilting the assembly so produced to a horizontal position and laterally moving the assembly to a contact seal surface, connected to a discharge chamber isolated from the environment, so there is a continuous seal from the environment between the contents of the bulk bag and the enclosed discharge chamber, opening the bulk bag by a glove box, tilting the drum containing the opened bulk-bag enclosed in the envelope sealed by contact seal to the discharge chamber and rotating said drum when necessary until the contents of the bulk bag is emptied through the discharge chamber, removing the emptied bulk-bag enclosed in the envelope through an exit port-hole in the discharge chamber into a separate disposable poly-tube sealed to said exit and disposing of the sealed package so produced in an environmentally acceptable manner.
