Stop, drop and roll is a simple fire safety technique taught to children, emergency service personnel and industrial workers as a component of health and safety training in English-speaking North America, and most other English-speaking countries. It involves three steps a fire victim should follow to minimize injury in the event their clothing catches fire.

Stop, drop and roll consists of three components.

Stop – The fire affected person must stop, ceasing any movement which may fan the flames or hamper those attempting to put the fire out.

Drop – The fire affected person must drop to the ground, lying down if possible, covering their face with their hands to avoid facial injury.

Roll – The fire affected person must roll on the ground in an effort to extinguish the fire by depriving it of oxygen. If the victim is on a rug or one is nearby, they can roll the rug around themselves to further extinguish the flame.
