2. Prevention of asphyxiating gas poisoning
In people’s lives, there are frequent news reports that cause flammable, toxic gas leaks, or poor use of safety awareness, causing serious safety incidents. These safety accidents have caused property losses and casualties, affecting people's normal lives and normal factory production.
1. Hazard of irritating gases
Many industrial production processes have irritating gases such as electric welding, electroplating, smelting, chemical and petroleum industries. These gases are mostly corrosive and can cause acute poisoning by entering the body through the respiratory tract. The common feature of the toxic effects of irritating gases on the body is that it has different degrees of irritation to the eyes, respiratory mucosa and skin. It is mainly local damage, but it can also cause systemic reactions. "Triacid" vapor can stimulate the respiratory mucosa, but also cause skin burns; long-term exposure to low concentrations of acid mist can also stimulate the teeth, causing tooth erosion. Chlorine, ammonia, sulfur dioxide, sulfur trioxide and other water-soluble large, wet parts that are vulnerable to damage. If these gases are inhaled, they dissolve in the mucosa of the upper respiratory tract, directly irritating the mucous membranes, causing increased congestion, edema, and secretion of upper respiratory tract mucous membranes, resulting in chemical inflammatory reactions, and symptoms such as runny nose, itchy throat, and cough. Nitrogen oxides, phosgene, and other water-soluble substances are small. When they pass through the upper respiratory mucosa, they rarely cause hydrolysis, so the mucosal irritant effect is slight; but it can continue to penetrate into the bronchi and alveoli, and gradually acts on the water on the mucosa, and on the lung tissue. Produce a strong irritant and corrosive effect, severe pulmonary edema.
For example, sulfur dioxide is mainly derived from the combustion products of sulfur-containing fossil fuels (coal and petroleum). Sulfur dioxide-containing exhaust gas is also discharged during the production of metal minerals, wool and silk bleaching, and chemical pulp and acid production processes. Sulfur dioxide is a colorless, sulfuric acid, strong irritant gas, soluble in water, contact with water vapor to generate acid, strong stimulation of the eyes and respiratory tract and corrosion, can cause throat and bronchial inflammation, respiratory paralysis, severe Causes pulmonary edema. It is an active poison that can be oxidized to sulfur trioxide in the air to form sulfuric acid fumes, which are 10 times more toxic than sulfur dioxide. Sulfur dioxide has a strong corrosive effect on the respiratory organs, causing inflammation of the nose, throat and bronchi.
The common asphyxiating gases are carbon monoxide, hydrogen sulfide, and cyanide. When they enter the human body, they impede the ability of the blood to transport oxygen or the ability of tissues to use oxygen, resulting in hypoxia and tissue damage. The main preventive measures are to strengthen confinement, ventilation, strict safety operation regulations, strengthen publicity and education, popularize first aid and prevention knowledge, and do a good job of pre-post and regular health checkups.
For example, carbon monoxide is a colorless and odorless gas that can be uniformly dispersed in the air, slightly soluble in water, and generally chemically inactive, but can cause explosions when the concentration is 13 to 75%. Carbon monoxide is mostly a product of incomplete combustion of equipment such as industrial furnaces and internal combustion engines, as well as leakage from gas equipment. Carbon monoxide is highly toxic, and its affinity for human heme is greater than 250 to 300 times that of oxygen and human heme. After the human body inhales carbon monoxide-containing air, carbon monoxide quickly combines with heme to greatly reduce the ability of erythrine to absorb oxygen, causing hypoxia in various tissues and cells of the human body, causing suffocation and blood poisoning, and causing death in severe cases. When the concentration of CO in the air reaches 0.4%, people will lose consciousness in a very short period of time, and if they do not respond in time, they will die of poisoning.
