<p>A fire extinguisher comprises a vessel (2) containing extinguishing agent and a nozzle (3) arranged, in use, to deliver the extinguishing agent to a scene. The extinguisher further comprises a sensor (5) for receiving infrared radiation from the scene. Data from the infrared sensor may be processed and used to derive a visual image or other visual indication of infrared radiation from the scene. Alternatively, the data may be used to provide an audible and/or tactile signal to a user. The provision of an infrared sensor permits a user of the extinguisher to locate the centre of the fire and release extinguishing material in one operation. Previously, a user had to firstly locate the centre of the fire using imaging equipment, then put that equipment aside and take up the fire extinguisher, directing the nozzle approximately in the region of the fire.</p> |
