Smoke and toxic gases rise to the ceiling first. In a fire, the breathable air is closest to the floor. If you encounter smoke while escaping, get down on your hands and knees and crawl to the nearest exit. Just a few breaths of toxic smoke can cause disorientation and loss of consciousness.

Never throw water on a grease fire — it will cause the burning oil to explode and spread the fire rapidly. Instead, turn off the heat source, carefully slide a lid over the pan to smother the flames, and leave it covered until it cools completely. If the fire is too large to control, evacuate and call 911.
