Abstract
Abstract A device for extinguishing gas and oil well fires, particularly multiple-well, offshore installations, and for preventing loss of oil to the surrounding area after fire extinction comprises a hood adapted to be placed over the well site, the hood having a curved interior upper wall which deflects the gushing oil into a catch basin from which it can be pumped away.
