Abstract: A hot oil/fat fire extinguisher, comprising a frame which supports a smothering material in a horizontal plane and a handle which allows the safe and effective application of the smothering material to a container of burning fat/oil. When not in use it may be stored in a holder which can be wall mounted. In the event of a container of fat/cooking oil igniting, the extinguisher can be removed from the holder by using the handle and presents a smothering material of a size and shape suitable for covering the container of burning fat/oil. This is placed over the container in the manner prescribed in the instructions of use, depriving the burning surface of air and achieving extinction.
