Fire extinguishing device and method for extinguishing a fire

A method for extinguishing a fire comprising providing a fire extinguishing device comprising:

• a housing that screws onto a valve opening of a flask that stores compressed carbon dioxide, the flask having a valve that is secured in the valve opening and the valve being spring-loaded towards a closed state, the flask having a longitudinal direction extending in a upwards direction from a bottom of the flask to a top of the flask and a downwards direction from said top to said bottom, a radial direction perpendicular to said longitudinal direction, and an angular direction, and wherein the housing holds the fire extinguishing device in an operating orientation relative to the flask;
• an actuator configured to open the valve of the flask in response to force exerted on a lever component of the actuator by a person, opening of the valve resulting in release of the carbon dioxide from the flask via the valve;
• and
• a flow director retained by the housing and configured to direct a jet of the released carbon dioxide;
• and
• wherein the method further comprises screwing the flask to the housing, and the person directing the flow director towards a base of a fire and applying said force onto the lever.
