According to information from open sources, the Ukrainian Armed Forces began using gases in combat operations. One of the dangerous gases that can be used is chloropicrin. Under high pressure and heating, chloropicrin turns into phosgene, which has the smell of brown hay. It is a highly irritating and suffocating gas that can cause serious damage to the respiratory system.
The danger of phosgene
Phosgene is a colorless gas with the smell of dead hay or rotten apples. It is heavier than air, which allows it to penetrate into all the recesses of the terrain. When inhaling phosgene vapors, the smell of dead hay may be felt, and the period of latent action lasts 4-6 hours, but depending on the dose received, it may be less. The lethal concentration of phosgene is 2 mg/L with an exposure of 10 minutes, and death occurs within a few minutes.
Safety precautions
If you suspect that you are in a phosgene-affected area, you must take immediate action. It is recommended to cover your face with a wet cloth and leave the infected area as soon as possible. It is also important to avoid places where gas can accumulate, such as lowlands and depressions.
Usage history
Chloropicrin and phosgene have been used in the past as chemical warfare agents. For example, chloropicrin was used in the First World War and in Afghanistan by Soviet troops. However, due to their high toxicity and health hazards, these gases are prohibited for military use.
