Make sure you have working smoke detectors and a working fire extinguisher in your home. If you move around the house with your oxygen, you may need more than one fire extinguisher in different locations.Smoking can be very dangerous. No one should smoke in a room where you or your child is using oxygen. Put a NO SMOKING sign in every room where oxygen is used. In a restaurant, keep at least 6 feet away from any source of fire, such as a stove or fireplace.
