Presented is a device which includes a container within which is confined a body of material that will absorb liquid oil and gasoline and also the fumes generated by these two liquid contaminants. The container is provided with a multiplicity of openings formed in such a way as to prevent the intrusion of water with which the oil and gasoline may be mixed, but which permits the passage of the oil and gasoline. The container is constructed in such a way that as the weight of the container increases because of the absorption of liquid oil and gasoline floating on water, the container progressively sinks into the water until the openings in the container are completely submerged, thus entrapping within the container all of the oil and gasoline that has been absorbed and the fumes thereof. When placed in a compartment where liquid oil or gasoline is present in the absence of water, the device will absorb the oil and gasoline and vapors thereof and retain them trapped within the container.
