Fire blankets are usually used for putting out small fires in or around the kitchen and are particularly useful for Class F fires involving cooking oils. They can also be used for waste bin fires and to extinguish clothing fires.
Walk slowly towards the fire and stretch out your arms in front of you. As the blanket touches the top of the stove, place it over the fire. Leave the blanket over the pot for at least thirty minutes. If it's safe to do so, turn off the gas/electricity at the stove or at the main supply.
