ABSTRACT:
A system for disposing of large amounts of infectious hospital waste includes a generally sealed enclosure containing an apparatus for delivery, disintegration, and decontamination of waste materials. A dual conveyor arrangement provides a positive delivery of large waste containers to be disposed to a disintegrator while preventing material from being thrown from the disintegrator. The disintegrator comprises two, large, counter-rotating hammermills capable of effectively disintegrating articles of substantial size. The system enclosure is maintained at a negative pressure and adapted to prevent escape of airborne contamination from the system. A variety of protective features is also incorporated into the system to clear the disintegrator in cases of overload, to avoid power surges upon system start-up, and to effect an orderly shutdown of the system.
