Oxygen is a nonflammable gas.I have a Liquid Oxygen Vessel with about 145K gallons on Oxygen in it. I believe this constitutes a potential explosion hazards!
Those are defined as flammable and will have a red placard when shipped. Oxygen is defined as an oxidizer and will have a yellow placard when shipped. An oxygen enriched atmosphere does increase the chances that a fire will start. It does not lower the ignition point for the flammable or combustible product. It does, however, greatly increase the intensity of the fire and the speed of the fire once the product is ignited.So is LP, Acetylene, propane, etc. These are also non-flammable by themselves. The environment needs a sufficient supply of oxygen for these gases to be flammable.
Not true. The presence of oxygen in abnormal concentrations does not change the ignition point of the flammable material and has no effect on the ease of starting the fire.As the oxygen level increases, it becomes easier to start a fire.
You don't need increased oxygen concentrations for spontaneous combustion to occur, however you need non-petroleum oils.It is even possible to start a fire using pure oxygen where no spark or flame exists, especially if the oxygen comes into contact with oily materials.
Spontaneous combustion results from the increased temperature when the product involved oxidizes. The faster the product oxidizes the more heat. Petroleum oils do not oxidize fast enough to reach their ignition temperature, at least not at normal temperatures. Some plant oils do. The most common in linseed oil and other oils used in oil based paints. Also biodiesel is a plant oil based product and can spontaneously combust. Petroleum oils will spontaneously combust in the presence of strong oxidizers such as chlorine. A number of Wal-Mart's burned before they found that they shouldn't be storing motor oil and pool chemicals close to each other.That's interesting. Why not petroleum oils?
