ABSTRACT:
An improved contamination control boom having walls defining an elongated hollow flotation chamber. Apertures may be provided in the walls of the flotation chamber to allow material from the body of liquid on which the boom is utilized, which may be the liquid, the contaminant, or a mixture thereof. Pump means may be incorporated to remove the material from the flotation chamber. A float means is positioned inside the flotation chamber to provide a desired freeboard for the condition of liquid in the flotation chamber. Special materials may be utilized to fabricate the boom for high temperature resistant applications where the contaminent is burning, but the boom must continue to operate as a boom during the burning.
