A floating boom comprising a number of separate buoyancy chambers (1), a skirt (2), a ballast (3) and an air supply conduit (4), is safeguarded against bursting of the buoyancy chambers (1) by means of at least one duct (8) extending from the interior of the buoyancy chamber (1) to an outlet that is located between the buoyancy chamber (1) and the lower edge (6) of the skirt. By letting the air supply conduit connection with each single chamber open into said duct (8) a non-return valve function is further obtained in a simple manner. There is also described a method of obtaining supplementary security against all buoyancy chambers (1) being emptied if a single buoyancy chamber (1) is punctured during the use of the floating boom. |
