Abstract
A barrier for impeding the spread of oil spilt on water comprising two angled buoyant rigid elements (9 and 10) each of which is moulded onto a respective angled stiffener (2 and 5) to form Z-shaped members (1 and 4) in cross-section. The two Z-shaped members (1 and 4) are positioned back to back so that each is a mirror image of the other. The ends of the angled stiffeners (2 and 5) remote from the angled buoyant rigid elements (9 and 10) are rotatably connected and the two angled buoyant rigid elements (9 and 10) are releasably joined by a fastener 7. A flexible membrane (3) passes around the ends of the angled stiffeners (2 and 5) remote from the angled buoyant rigid elements (9 and 10), each end of the membrane (3) being moulded into one of the angled buoyant rigid elements (9 and 10).
