Asphyxiating gases act on the characteristics of the human body and preventive measures for harm to the human body

Asphyxiating gas is a common harmful gas in industrial and agricultural production, which can be divided into two categories: simple and chemical.

Simple gases (such as nitrogen, methane, carbon dioxide, water vapor, etc.) are not toxic themselves, but if they are high in the air, the relative content of oxygen will be greatly reduced, followed by a decrease in the partial pressure of arterial blood oxygen, resulting in hypoxia in the body; chemical gases (such as carbon monoxide, cyanide, hydrogen sulfide, etc.) can make the transport of oxygen and the function of tissue oxygen impaired, resulting in hypoxia of tissue tissues. The brain is most sensitive to hypoxia, so asphyxiating gas poisoning is mainly manifested as a series of symptoms of hypoxia of the central nervous system, such as dizziness, headache, irritability, disorientation, vomiting, drowsiness, coma, convulsions, etc.

Preventive measures for the harm of suffocating gas to the human body: often determine the concentration of suffocating gas in the working environment, repair pipelines to prevent air leakage; the production process of suffocating gas should be sealed and have ventilation facilities; install automatic alarms in more dangerous areas; all who enter the dangerous area must wear gas masks when working, and should leave immediately after operation, and rest appropriately; it is best to work with many people at the same time during operation, so as to facilitate self-rescue and mutual rescue in the event of an accident.

Strengthen safety education, popularize the prevention of asphyxiating gas poisoning and first aid knowledge, once the poisoned person is found, it should be immediately moved to fresh air, and pay attention to keeping the patient warm, and send it to the hospital for rescue as soon as possible.

【Knowledge learning】The clinical manifestations of asphyxia gas poisoning are mainly based on the symptoms of hypoxia of the central nervous system, and the key to its treatment lies in correcting hypoxia and giving hyperbaric oxygen therapy. In addition, according to the pathogenicity of different types of gases, it is advisable to choose the corresponding therapeutic substances, such as cytochrome C, sodium nitrite - sodium thiosulfate, Meilan and the like.

Women, minors and the elderly who have obvious neurological diseases, cardiovascular system diseases, severe anaemia and pregnant women, minors and the elderly should not work in an operating environment with the presence of asphyxiating gas.
