See what happens when you pour water on a grease fire

2nd Annual Emergency Awareness Day


  • Normally a person's first instinct is to put water on a fire.....that is the worst move you could make on a grease fire.
  • The adage "oil and water do not mix" is due to the specific gravity of water being heavier than oil. By putting water on a grease fire the water sinks to the bottom of the cooking container where it becomes instantly heated........the explosive force of this instant steam forces the flaming oil up and out of the container thereby creating a much larger fire.
  • The single most important thing a person can do to prevent a grease fire is to never leave your cooking unattended.
  • REMEMBER A FIRE CAN START WHEN YOUR ATTENTION STOPS!
