A lid for an industrial waste container comprises a first lid section which is of relatively rigid, heavy construction and which is hinged to one side of the container. The first lid section defines an access opening to the container, which access opening is closed by a second lid section of relatively light weight. The second lid portion is hinged to the first lid section and a releasable catch is provided to releasably secure the first lid section in a closed position. Biasing means are provided to bias open the second lid section when the catch is released.
