ABSTRACT:
A drum for containing hazardous waste wherein a plurality of cam locks are associated with the drum to retain the lid thereof in sealed position when locked and to release the lid in the cam locks' open position when access to the drum is desired, thereby obviating the need for threaded lids which are difficult to close as well as open, especially when they have been weathered.
