phosgene gas burning refrigerant

Fri Oct 23 2020

... A byproduct of burning hydrocarbon chloride is phosgene gas, which is a lethal gas in certain concentrations. The myth that phosgene gas is formed when R-22 is burned needs to die, seriously. Refrigerant summary It's a deadly gas generated when refrigerant burns. The burning sensation you get when torching refrigerant gas is not the phosgene, it is acids that form. Phosgene is a valued industrial building block, especially for the production of precursors of polyurethanes and polycarbonate plastics. Digital linear actuator. That clear, pale yellow, refrigerant oil, comes out of the compressor black as coal. I lost a buddy of mine about 15 years ago to phosgene gas poisoning, he got in a hurry, breathed a bunch of it, walked around for a week feeling terrible, doc told him it was the flu. Phosgene gas. Phosgene is the organic chemical compound with the formula COCl 2.It is a colorless gas; in low concentrations, its odor resembles that of freshly cut hay or grass. Your nose, throat, and eyes begin to burn. device that changes the rotational force of an eev stepper motor to a push or pull motion opening and closing the valve. If a refrigerant containing chlorine is forced to burn, phosgene gas is created which is poisonous. It takes burning or overheating of the refrigerant in order for it to chemically change into phosgene gas. This again would only happen in an open flame environment. There may be a minute bit of phosgene in there but it is not what you are smelling. Personally I find that burning r404 or r410a smells just as bad as r22 which tells me that the smell is from something other than phosgene. Phosgene was used in WW1 as a poisonous gas in trench warfare so it is nothing to be taken lightly. Notably, phosgene is a poisonous gas and poses a serious threat to health. A very toxic gas which has been used as a weapon in past wars. For example, while R12 itself is similar to the halon used in fire extinguishers, when R12 is mixed with mineral oil—the most commonly-used lubricant oil in R12 systems—and aerosolized and burned, it creates phosgene gas, which was used as a chemical agent in WWI. refrigerant gas handling protocol outlined in this handbook, which has been carefully designed to: 1. Burning refrigerant in an open flame creates Phosgene gas. Freon is a tasteless, mostly odorless gas. The products of combustion for the HFO refrigerants can be very dangerous… something anyone who has taken a face full of phosgene gas-burning R12 should realize is an important thing to worry about. if any burning would occur it would be from the refrigerant oil and not the refrigerant. If a flame should happen then yes its nasty stuff. You know when it is around. Gas mask for phosgene gas,IE burning freon? One thing that will NOT be formed is phosgene gas. Refrigerant contains chemicals called fluorinated hydrocarbons (often referred to by a common brand name, “Freon”). Freon is used as a refrigerant in car air conditioning systems, and older models have the R-12 variety of the gas. What other problems will you find when dealing with a burned out compressor? Additionally, not all the refrigerants have the same capacity or efficiency so some applications can be challenging. poisonous, colorless gas that can be generated by the burning of refrigerant gases smells like freshly cut hay, as you breathe in it forms hydrochloric acid carbon dioxide. At least most of the refrigerant manufacturers have stopped listing phosgene as one of the decomposition products of R-22 in their MSDS, its a start. Car Fires. It takes you breath away. The good thing about phosgene? If such a car catches fire, it is important not to inhale the fumes because the R-12 will turn into phosgene (nerve gas), a lethal chemical.
