⛽ Brake cleaner welding phosgene gas?

The gas station close to the shop was out of carb cleaner so I picked up a can of brake cleaner and went thru my regular routine. I even had the shop door open and the exhaust fan on. I started TIG welding (3pm Thursday) and had no problem in the beginning.

⛽ 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. Phosgene is a valued industrial building block, especially for the production of precursors of polyurethanes and polycarbonate plastics.. Phosgene is very poisonous and was used as a chemical weapon during World War I, where it was responsible for 85,000 deaths.. In addition to its industrial production, small amounts occur from ...

According to the available information, phosgene is produced as a component of welding fumes when metal that’s been cleaned with a solvent or degreaser (brake cleaner is the usual culprit). In one example, a man using repairing a refrigerator was exposed to phosgene as a result of heating the coolant with a welding torch.

When this chemical is exposed with excessive heat and argon (used in MIG and TIG welding) it also produces phosgene. Some Phosgene facts. Google Phosgene and read more! It can be fatal with a dose as little as 4 parts per million. Symptoms can be delayed from 6-48 hours after exposure. There is NO antidote for Phosgene.

What phosgene is. Phosgene is a major industrial chemical used to make plastics and pesticides. At room temperature (70°F), phosgene is a poisonous gas. With cooling and pressure, phosgene gas can be converted into a liquid so that it can be shipped and stored. When liquid phosgene is released, it quickly turns into a gas that stays close to ...

The radiation from welding arcs causes trichloroethylene vapour to decompose to products that are readily detected by smell. The primary decomposition products are dichloroacetyl chloride and hydrogen chloride but phosgene, which has very low exposure limits (long-term limit 0.02ppm, short-term limit 0.06ppm), is also formed.

In addition to the significant risks Tetrachloroethylene carries, the substance becomes an extremely poisonous gas called Phosgene when it is heated to temperatures above 315 degrees Celsius. This means that a workplace that uses brake cleaner AND ALSO uses extreme heat on the premises (such as welding) is a seriously dangerous place to be.

A less-common example – but very relevant for anyone working in HVAC – is phosgene gas. Responsible for upwards of 85 percent of all deaths caused by chemical warfare in World War One, phosgene gas also happens to be a byproduct generated when brazing certain metals, and can also become present when testing for leaks using an antiquated method on refrigeration systems that run chloromethanes, R12 and R22.

Mustard gas kills in a more painful way and is more of a horror weapon. It condenses onto the ground as an oily liquid and remains active in the soil for months under certain weather conditions. Mustard gas causes blistering, vomiting, and internal and external bleeding. Fatal exposures can take four to five weeks of pain to kill the victim.

Phosgene gas exposure from working with freon.?

Phosgene gas exposure can be very deadly without you even knowing until it is too late. The most common way of being exposed to phosgene is brazing where refrigerant is present. Freon is a hcfc which when in contact with extreme heat puts off the phosgene gas. This gas can kill you rapidly if exposed to 50ppm especially if it was inhaled. You may experience tighting of the chest and your throat feeling like it is burning. See a physcian if exposure is thought to have happened. If you have a leak in a refrigerant line reclaim all refrigerant before fixing leak or you might face DEATH.
