Directions for use

Oil Spills at Sea

Unitor™ Seacare OSD-2™ is used undiluted by direct spraying to clean up oil spills at sea. Allow some time for the oil to absorb the Unitor™ Seacare OSD-2™ and then disperse mixture by vigorous agitation using fire hoses, the ship's propeller, breaker boards towed behind work boats, etc. Unitor™ Seacare OSD-2™ should not be used in an area of sea of a depth less than 20 metres or within one mile of such areas exept in accordance with the advice of the local District Inspector of Fisheries of Ministry or Scottish Office Agriculture, Environmental and Fisheries Department (SOAEFD).

Oil on Beaches and Shore Line Unitor™ Seacare OSD-2™ should be applied neat by spraying over oiled areas. Allow time for the oil to absorb the Unitor™ Seacare OSD-2™ then follow by washing down the beach or rocks, etc. The treatment rate depends on the type and thickness of the oil spill, also on the age and condition. Under conditions where it is a thin slick of oil, 1 litre of Unitor™ Seacare OSD-2™ is enough to treat approximately 10 square metres of oil. In many cases, several applications may be necessary.

Oil Spill on Deck Remove as much of the oil as possible, then spray Unitor™ Seacare OSD-2™ over area covered by the oil and allow some time for it to be absorbed. Disperse the mixture with water by means of a fire hose. Depending on type of oil it may be necessary to use several applications.
