The disclosure relates to a waste bin having an inner steel container for refuse and an outer thermoplastic hood form cover having a domed top wall and side ports through which refuse may be deposited in the container. A lid for the container is mounted on the underside of the top wall of the cover and is supported on a central stud extending through the cover by means of a polythene washer held on the stud by a nut. If a fire should develop in the container the resulting heat will cause the washer to melt releasing the cover to fall onto the top of the container therefore preventing air flow into the container to restrict and extinguish the fire.
