Oil pollution clean-up. Team of workers cleaning up a beach polluted by an oil slick. At centre left workers deploy a floating boom designed to stop oil slicks from reaching the shoreline. At right are two tractors pulling tanks in which the pollutant has been collected. This slick originated in a spill of about 70,000 tonnes of light crude oil from the oil tanker Sea Empress off the coast of Milford Haven, Wales, in February 1996.
