ABSTRACT:
Waste material is passed from a cell 10 through a port 12 into drum 48 which has a mouth 49 with a removable lid 54. A port door 28 includes an electromagnet 54a to hold the lid to the door 28 and both are moved into the cell to allow loading of the drum and after re-closure of door and lid swaging tools 34 operate to deform the lid to form one or more lips which engage under the margin around mouth 49 to resist separation of the lid from the drum.
Seals 30, 32, 52 are provided.
