Okay, don’t ever leave any aerosole like Pam next to the stove while cooking, it could explode if it gets too hot! Also if making a barbecue check and make sure that there is nothing flammable like empty paint cans nearby.
If someone goes on fire roll on the ground and try to smother the fire with a sweater or whatever you have nearby, throw water on the victim and if the don’t take off clothing unless you’re sure the burns didn’t get to the skin.
