Phosgene is an organic chemical compound with the formula COCl 2. It is a toxic, colorless gas; in low concentrations, its musty odor resembles that of freshly cut ...
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
Phosgene is considered safe at 0.1 parts per million during an eight-hour exposure, or 0.2 ppm for a 15-minute exposure. The eight-hour exposure threshold would have to be even lower when ...
In January 1982, a phosgene leak exposed 24 workers, all of whom were admitted to a hospital. None of the workers had been ordered to wear protective equipment. One month later in February 1982, an MIC leak affected 18 workers. In August 1982, a chemical engineer came into contact with liquid MIC, resulting in burns over 30% of his body.
The daily Svenska Dagbladet newspaper said authorities had found traces of phosgene. The gas has a strong odor that can cause vomiting and breathing trouble and was used as a weapon in World War I.
Phosgene oxime is classified as a vesicant even though it does not produce blisters. [6] It is toxic by inhalation, ingestion, or skin contact. The effects of the poisoning occur almost immediately. No antidote for phosgene oxime poisoning is known. Generally, any treatment is supportive. Typical physical symptoms of CX exposure are as follows:
Phosgene (CG) Disulfur decafluoride; Perfluoroisobutene; Acrolein; Diphenylcyanoarsine; Phosgene is the most dangerous commonly used pulmonary agent (although disulfur decafluoride and perfluoroisobutene are both even more dangerous, with respectively 4 and 10 times the lethality of phosgene, neither is widely used). It is a colorless gas under ...
On a Trinity County farm in 2023, an environmental health report shows officers found a 3-pound tin of Fumitoxin, a poison that emits phosgene gas, along with evidence workers there were suffering ...
