FIRE EXTINGUISHING DEVICE AND METHOD FOR EXTINGUISHING A FIRE

Fire extinguishing device (100). The invention is characterised in that the fire extinguishing device comprises a flask engagement means (110), arranged to engage with a flask (10) for compressed carbon dioxide and to hold the fire extinguishing device in an operating orientation in relation to such a flask; an actuating means (120), arranged to apply a pressure on a valve (13) of said flask when in said operating orientation so that the valve as a result of said pressure opens and carbon dioxide flows out from the flask, which actuating means in turn comprises a lever means (121) for transferring a force applied by a user within said actuating means (120) for applying said pressure; and a carbon dioxide directing means (130), arranged to direct a jet (20) of carbon dioxide flowing out from the flask when said valve is open.
