The toxic and ecologically accumulative nature of PFOS (perfluorinated-octyl-sulfonate) has been known for some time. The substance is an industrial chemical found in a number of products, including fire foam used in the oil industry.
"Due to information that has come to light, Hydro has decided to replace and incinerate this environmentally harmful fire foam," says Ståle Teigen, leader for Hydro's department of external environments in Bergen.
Evaluating safety risk
"We don't want to have this stuff in our fire-foam tanks and have decided to replace it in anticipation of an imminent ban," says Teigen. Hydro will start the replacement process with the supplier company at the end of the year.
