The Club has received notification of two explosions on bulk carriers loading wheat at Rio Grande Do Sul, Brazil, recently. It is believed that the explosions are linked to the use of phosphine fumigants. The cause of the incidents is currently under investigation. Members are reminded of the potential explosion danger posed by fumigants. The IMO has issued guidance on the use of fumigants in a circular: IMO MSC.1/Circ.1264 Members whose vessels are undergoing fumigation at Rio Grande Do Sul should contact the local agents or P&I correspondents for advice on the current situation with respect to fumigants.
