Victims whose clothing or skin is contaminated with liquid phosgene (ambient temperature below 47°) can secondarily contaminate response personnel through direct contact or off-gassing vapor. Rescue personnel should use breathing apparatus and chemical protective clothing if there is a possibility of exposure to unsafe levels of phosgene.

2024年9月6日 · Phosgene is a toxic gas or liquid that can cause damage to the skin, eyes, nose, throat, and lungs. Signs and symptoms depend on how the amount of phosgene, how the person was exposed, and for how long. If you were exposed, get clean and get medical care.

2015年1月30日 · In February 1918 one soldier of the 1/22nd London Regiment developed a sore throat and reported that he had been gassed. Although there had been no reports of a gas attack, panic spread - and...

2022年12月26日 · Determine the pathophysiology of phosgene toxicity. Identify current management strategies for phosgene toxicity. Identify key elements of history and physical that are characteristic of acute phosgene toxicity. Communicate differential diagnoses and how to distinguish them from phosgene toxicity.

Victims with unknown phosgene exposure must be closely observed. Victims exposed only to phosgene gas that have no evidence of skin or eye irritation may be transferred immediately to the Support Zone as they do not pose substantial risks of secondary contamination to personnel outside the Hot/Warm Zones.

Victims with inhalation doses of < 25 ppm/min and without clinical signs and symptoms require no immediate medical attention. Exposure to a cumulative dose of 50 ppm x minutes may cause pulmonary edema; a dose of 150 ppm x min will probably cause pulmonary edema and a dose of 300 ppm x min is likely to be fatal.

Phosgene remains one of the most dangerous of today's high-volume chemicals, as evidenced by the deaths and widespread evacuations caused by its release in industrial accidents. The respiratory system is most severely harmed by exposure to phosgene.

Patient/victims exposed to low concentrations of phosgene (CG) vapor may not experience any irritation, or they may have only mild irritation of the upper airways; this allows them to inhale phosgene (CG) for a longer time and more deeply into the lungs.

Inhalation is the most important route of exposure for phosgene. Because of phosgene's mild upper respiratory, eye, and skin irritancy and mildly pleasant odor, an exposed victim may not actively seek an avenue of escape before lower respiratory damage has occurred (Currie et al. 1987a; Lipsett et al. 1994).

Phosgene is a highly toxic gas to which accidental exposure may occur in occupational workers. This case report describes the clinical presentation and management of accidental phosgene poisoning happened after the leakage of phosgene gas from nearby pipeline.
