(57) Abstract A boom (10) for collecting material floating on the sur- face of a body of water comprises a first collapsible tube (16) which can be stored either as flat layers of folded material or by rolling it on a roller (R). Transverse seals (15) are provided along the length of the tube (16) to provide . longitudinal se- quence of compartments. A plurality of chemicals (19a, 19b) are disposed in each compartment, the chemicals (19a, 19b), when mixed, being capable of producing an inflating gas. One of the chemicals (19b) is disposed in a plastic pouch (20) which is frangible under pressure applied to the rollers (R) during the deployment of the boom from its stored condition. In a modification, a small collapsible tube (30) is provided to supply pressurized gas to all of the compartments, thus inflat- ing any compartment that is underinflated by the gas pro- duced by chemical mixture.
