Gasoline poisoning.
Gasoline is a narcotic poison, which has acute poisoning, aspiration pneumonia and chronic poisoning.
Acute gasoline poisoning generally occurs when you enter the oil tower without protective measures, clean the oil storage pipe, or the distillation equipment in the refinery fails. The clinical manifestations of acute gasoline poisoning are dizziness, headache, palpitation, weakness of limbs, nausea, vomiting, blurred vision, drunkenness, irritability, unsteady gait, temporary loss of consciousness and other upper respiratory tract irritation symptoms.
Severe poisoning is toxic encephalopathy after inhaling high concentration gasoline vapor, and a few can produce brain edema, neck stiffness, flushing, pulse fluctuation and shallow breathing; Inhalation of extremely high concentrations of gasoline can lead to sudden loss of consciousness, reflex respiratory arrest and death. Some patients may have symptoms of toxic psychosis, such as panic, euphoria, hallucinations, and impermanence of crying and laughing.
When entering the high-concentration gasoline working environment, you should strictly abide by the rules and regulations of safe operation, carry out forced ventilation, do a good job of personal protection, and wear gas-supplied gas masks. Diesel oil is a volatile liquid, if it is not burned, a small amount of inhalation will not affect people's health; Excessive inhalation of diesel oil droplets can lead to aspiration pneumonia, and skin contact with diesel oil can cause contact dermatitis and oil rash.
Because of its strong adsorption, soot in diesel vehicle exhaust can adsorb carcinogens (such as "benzo ratio") and metal ions under normal circumstances. Because of their extremely small particle size, if inhaled directly into the lungs, their toxicity will increase the possibility of respiratory tract infection and even induce cancer.
If you are exposed for a long time, you should eat a diet rich in vitamins, which is conducive to the prevention and treatment of chronic poisoning; Limit fat intake, ban alcohol and avoid spicy food.
Oil and gas from gas stations will be directly absorbed by human body through respiratory tract and skin, which will aggravate human body's metabolic function and affect health. It is said that they will not have fertility for a long time (1 for both men and women).
Long-term gas station staff; The main component of oil in gas station is gasoline, so we should understand the harm of gasoline to human body. Gasoline is mainly used as power fuel for transportation. Rubber, paint, dye, printing, pharmacy, adhesive and other industrial gasoline as solvent. Cleaning and decontamination of machine parts and clothes and pretreatment of electroplating products use gasoline as degreasing agent. Because of different producing areas and production methods, the composition and toxicity of gasoline are also different. Gasoline is volatile and soluble in fat. In the production environment, it is mainly inhaled into the human body through the respiratory tract in the form of steam and circulated to the human brain through blood, causing anesthesia. It also has toxic effects on central nervous system and peripheral nerves, and has adverse effects on hematopoietic function of bone marrow. The effect on bone marrow may be caused by benzene mixed in gasoline. The mild symptoms of acute poisoning are anesthetic symptoms, such as trance, unsteady gait, dizziness, nausea, vomiting, conjunctival congestion, cough and so on. In severe cases, coma, convulsion, muscle spasm, dilated pupils, dull light reflex or disappearance occur after inhaling high-concentration gasoline. Some cases may have stiff neck, shortness of breath, blood pressure fluctuation and cyanosis of lips. Check for hepatomegaly and abnormal liver movement. In severe cases, sequelae such as epilepsy, optic neuritis and polyneuritis can be left behind. Under special circumstances, such as the accidental inhalation of gasoline into the lungs by the straw of a car driver, it can cause bronchitis, chemical pneumonia and pulmonary edema. The clinical manifestations are fever, severe cough, chest tightness, blood in sputum, superficial breathing and cyanosis. The examination showed an increase in white blood cells. Chronic gasoline poisoning is mainly manifested as dysfunction of central and autonomic nerves, neurasthenia syndromes such as dizziness, headache, insomnia, nightmares, fatigue and memory loss, myasthenia, tremor, numbness of hands and feet, high and low blood pressure, excitability, moodiness, excitement and inhibition, and some of them may have hysteria-like symptoms. Contact with gasoline can make the skin dry and chapped, leading to keratinized dermatitis. Women are sensitive to gasoline. In addition to the above-mentioned neurological symptoms, abnormal menstruation and cycle disorder can also occur.
