<human>:  How can I put out a grease fire?
<bot>: To put out a grease fire, the best thing to do is to remove any possible sources of fuel and smother the fire by covering the pan with a lid, fire blanket, or damp towel. Ensure that all other combustible materials are kept away from the fire, and never pour water on the fire as it can spread the flames. If the fire is too large and can't be contained, evacuate the area and call 911 immediately.
