<u></u>
<u>INTERPRETATION-</u>
If anyone's hair or clothing catches on fire, immediately try to smother the flames with a wool fire blanket, or cotton clothing. Do not ever try to smother flames with nylon clothing: it could melt onto the skin.
If the fire cannot be immediately smothered, force the person to the ground and roll them over and over, to smother the flames.
