(1) acute poisoning. Mild narcotic symptoms performance, excitement, trance, drunken-like, unsteady gait, tremor, can be hysteria-like episodes, and dizziness, nausea, vomiting and irritation symptoms are more common, such as tearing, conjunctival hyperemia World steel pipe network editing , cough. Inhalation of high concentrations of gasoline, the symptoms get worse, and soon followed by coma, convulsions, muscle cramps, delirium, dilated pupils unresponsive to light or disappear. In some cases may have a stiff neck, breathing fast and shallow, blood pressure fluctuations, cyanosis of lips. Some body temperature dysregulation, increased body temperature. Some cases of hysteria-like seizures, mental disorders, laughing and crying impermanence. Check the enlargement of the liver, abnormal liver function. Severe cases can leave epilepsy, optic neuritis, peripheral neuritis, lower limb paralysis.
gasoline has the role of fat, can cause central nervous system cells within the class of lipid balance disorders. Mainly for anesthetic effects on the central nervous system. Have some stimulating effect on the skin and mucous membranes. The role of the hematopoietic system, as containing aromatic hydrocarbons.
diagnostic principles based on short-term inhalation of high concentrations of gasoline vapor, or long-term inhalation of gasoline vapor and skin contact with gasoline, occupational history, clinical manifestations of central nervous system or peripheral nerve damage based, site health investigation and determination of gas concentration in the air, and the exclusion of other causes of similar disease only after the diagnosis.
gasoline toxicity depends on its physical properties and chemical composition. Ever low boiling point of gasoline, its volatile inhalation toxicity is also large; often contain some impurities such as unsaturated aliphatic hydrocarbons, aromatic hydrocarbons and sulfides such as gasoline, containing these impurities is toxic. The purpose of the explosion-proof and energy-saving, plus a certain amount of tetraethyl lead or methanol and gasoline, and its more toxic.
(2) aspiration pneumonia. The driver of the car port suction tube mistakenly gasoline inhaled or accidentally dropped oil pool, into the respiratory tract caused by the resulting gasoline. The clinical manifestations were fever, drama, cough, chest pain World steel pipe network editing , bloody sputum, 1:3 lip cyanosis. X-ray examination with atypical pneumonia. Such pneumonia cure is slow, often delayed for months.
opportunities for contact in the refining process directly by skin contact or inhalation of gasoline vapor. Gasoline is mainly used for power fuel for transport vehicles. Rubber, paints, dyes, printing, pharmaceuticals, adhesives and other industrial use gasoline as a solvent. Machine parts and clothing cleaning decontamination and electroplating products, pre-treatment with gasoline to finish.
physical and chemical characteristic of gasoline is colorless and has a special smell of the liquid, vapor density 3.5kg/m3, volatile, flammable, explosive, soluble in benzene, alcohol and carbon disulfide organic solvents, fat-soluble, insoluble in water. Gasoline by oil fractionation, the dry distillation of oil shale and synthetic. The main component of the aliphatic hydrocarbons, and extraction of impure and may contain a small amount of aromatic hydrocarbons and sulfides.
(3) chronic poisoning. Mainly the central nervous system and autonomic nervous system function disorders. Numbness, tremor, unstable blood pressure, excitability. Some patients with hysteria-like symptoms, said gasoline hysteria. Skin contact with gasoline appears dry, chapped and keratotic dermatitis. Contain small amounts of benzene, gasoline and allows blood like change. Women may have menstrual abnormalities.
toxicology of gasoline in the production and use mainly in the vapor form of the respiratory tract by inhalation, skin absorption very little. Gasoline due to low solubility in the blood, it could quickly enter the fat and lipoid tissue. After inhaling discharged with the breath of the prototype, a small part of the glucuronide in the liver is oxidized with the urine.
Gasoline poisoning (Kilolitre, unless otherwise poisoning)
principles of treatment of acute patients with mild to it from the scene, a breath of fresh air, and symptomatic treatment. Critically ill patients according to the principle of general anesthesia gas poisoning, first aid, pay attention to prevent the occurrence of cerebral edema. In patients with aspiration pneumonia, in addition to the processing of pneumonia in general, you should use antibiotics to prevent secondary infection. Can be taken to the symptomatic treatment of chronic poisoning.
of clinical manifestations of acute poisoning, aspiration pneumonia and chronic poisoning.
industrial production or the use of solvents gasoline process, caused by exposure to gasoline vapors or liquid body lesions of the phenomenon. Acute poisoning with neurological or psychiatric symptoms, mistakenly inhalation of gasoline can cause aspiration pneumonia; chronic poisoning manifested as neurasthenic syndrome, autonomic dysfunction and toxic neuropathy.
Chinese industrial enterprises, health standards under the shop of the solvent in the air petrol maximum allowable concentration 350mg/m3.
