Liquid oxygen is not flammable! It does however support vigorous combustion in anything even remotely flammable (like road tarmac, or human beings). That is because is is very reactive indeed. Being in liquid rather than gaseous form simply increases the concentration & availability of the element.
Keep oxygen at least 6 ft (2 m)away from flames or heat sources such as gas stoves, barbecue grills, space heaters, candles, and fireplaces. Do not use flammable products, such as cleaning fluid, paint thinner, or aerosol sprays, while you are using oxygen. Keep a fire extinguisher at home within easy reach. If you have an emergency, be sure to tell your fire department that you have oxygen in the house. Keep oxygen tanks upright.
