Guest guest Posted July 12, 2009 Report Share Posted July 12, 2009 Joy Liquid oxygen does nothing toward saturation that any other form of oxygen doesn't do and is not more dangerous. I'm sorry but your statement regarding liquid just isn't accurate. Furthermore, liquid is under less pressure and less of a hazard than are gaseous cylinders. If you use oxygen your house and clothing carries a higher oxygen saturation than if you don't. Doesn't matter the source of the oxygen. Liquid is converted to gas before it comes out. You are accurate as to the tubing being a risk, but thats true regardless of how the oxygen gets into the tubing. You touch the tubing to a heat source such as a gas flame or an electric range burner and the tube itself is lit by the source, then the oxygen running through it is going to act as an accelerant. Now, as to using gas with oxygen of any form, its a matter of personal risk and judgement vs. precaution. The least risk is to not use gas ranges. Gas furnaces aren't an issue unless you're lighting the pilot. Sitting in a room in front of a vent isn't the issue. It's not the gas thats the danger. It's the spark. Anything that sparks involves some risk, from your smallest appliance on up. I'm going to use an analogy. Riding in a car is dangerous to some degree. Yet we all take car trips. Riding in a car going 100 miles an hour is a risk most of us choose not to take just as is riding in a car with a driver who is intoxicated. Everything in between not riding in a car at all and riding at 100 miles per hour or with an intoxicated driver has more risk than not riding and less than the obvious risky choices. Do you ride with a friend who has had several wrecks? Do you ride in rush hour traffic? Do you ride at night? Oxygen suppliers must take the most conservative approach and warn you to use no gas, no electric razors, no small electric appliances and a lot of other things. Each involves some risk but most involve minimum risks. We here talk about the disasters but they are rare and far between. Now smoking in a house filled with oxygen is far riskier because the chances of dropping a cigarette or just an ash onto an oxygen saturated sofa is high. But smoking increases the odds of a house fire dramatically even without oxygen. How many fires are caused by someone falling asleep smoking? We each draw our boundaries. I would personally never allow anyone to smoke in my house or vehicle, but I wouldn't with or without oxygen. I will also never allow anyone to smoke near me. > > The liquid oxygen saturates clothing and house - DO NOT USE GAS IF YOU USE LIQUID O2.

Guest guest Posted July 20, 2009 Report Share Posted July 20, 2009 Joy Suppliers are sometimes misinformed. Especially those who want to not supply liquid for financial reasons. I don't know whether it was the driver or whom who told you. However, the fact is that liquid is maintained at a pressure of only 20 psi while compressed oxygen is at a pressure of 2000-3000 psi. Once it is converted into gaseous oxygen though, then liquid, compressed or concentrator is the same. The major warnings of liquid are to keep it in a ventilated area (true of all) and to keep it upright. Liquid isn't liquid when it's coming out of the reservoir. At that point its gas just like anything else. Back to the subject of kitchen dangers, while the largest number of house fires occur in the kitchen that has nothing at all to do with oxygen use. It has to do with people leaving things unattended. Grease fires occur when we go into the other room to watch tv and forget we were cooking or get tied up answering the door. There are very very few fires in homes attributed to oxygen use. In fact, there was a study conducted by the Joint Commission on the Accreditation of Healthcare Organizations several years ago covering 11 fires that occured in a 3 year period in the homes of oxygen patients. Patients died in 7 of the 11. In all 11 the patients were over 65 and cigarette smoking was the contributing factor in all 11. Common to most of the 11 were the following: 1-Patient lived alone, 2-Smoke detectors absent or not working, 3-Patient had cognitive impairment, 4-Patient had a documented history of smoking while the oxygen was running, 5-Patient wore flammable clothing. Having respect for all forms of oxygen is good. Having fear of everything associated with them is paralyzing. We would never venture out because we'd be scared of transporting in our car. We'd not wear wool or nylon for fear of static electricity. We wouldn't use anything electric while on them. We'd never cook. Oxygen providers and insurers have to warn us. We have to then make judgements we're comfortable with. For me, I'll cook, but it is on electric stoves. Don't have gas so don't have to decide. I do have gas heat and hot water and am not concerned. I'd carry it in my van in large quantities. However, I will not allow smoking in my house or near me under any circumstances. But, thats beyond my fear of fire, thats my desire not to be exposed. I will make sure all the smoke detectors in my home are working. There are a total of 10 (I was shocked). I will also keep fire extinguishers handy. Like Beth, I'm running from a real fire. But if I had a very small flare up (still very contained) I would take one shot at putting it out. > > > > > > The liquid oxygen saturates clothing and house - DO NOT USE GAS IF > > YOU USE LIQUID O2.
