The doctor spoke about the effects of chemicals on victims of the fire.

Due to a man-made fire, a person may be at risk of poisoning by combustion products, including hydrogen cyanide.Gorenje During the experiments, it was proved that the lethal concentration of the substance is released during the combustion of only 1 kg of polyacrylonitrile in a room with a volume of 30 cubic meters, Ekaterina Terentyeva, head of the Invitro medical examination department, told Izvestia on April 1. She explained the effects of chemicals on the body.

"The substance enters the body through the respiratory system. But sometimes it can also get through the gastrointestinal tract or intact skin," the expert noted.

According to her, inhaling the vapors of the substance in excess leads to loss of consciousness with paralysis of the respiratory center and death. Contact with low concentrations of hydrogen cyanide causes weakness, headache, nausea, arrhythmia, skin irritation, tremor, numbness, visual agnosia and dizziness.

"Hydrogen cyanide has a different depressing effect on the tissue respiration of different organs," Terentyeva added, adding that the central nervous system suffers primarily.

Lack of moisture in the soil increases the risk of peatland fires, experts say

Earlier, on March 9, Alexey Yurasov, professor of the Department of Nanoelectronics at RTU MIREA, Doctor of Physico-Mathematical Sciences, said that low-quality batteries not only do not have a long service life, but they risk creating serious threats to equipment and even health. Using such batteries, the risk of fire, explosion, corrosion of metal contacts and damage to devices cannot be excluded.
