Chinese name: 2,4,6 - trinitrotoluene; TNT English name :2,4,6-Trinitrotoluene; TNT; Trotyl physical and chemical properties of chemical formula: C6H2CH3 (NO2) 3 Molecular weight: 227.13 boiling point : 240 ℃ (Explosion) Melting point: 80.35 ~ 81.1 ℃ Relative density: 1.654 Vapor Pressure: 0.046mmHg (82 ℃) Solubility: insoluble in water, ethanol, ethyl ether, soluble in chloroform, benzene, toluene, acetone. Explosive limit: 240 ℃ Toxicology Acute toxicity: Rat oral MLD700mg/kg, rabbit oral MLD500mg/kg, in> 2mg/m3 unpleasantness in the environment, and cause slight changes in the blood. The person I 1mg/kg for 4 consecutive days, no hematologic changes. The acute lethal dose were estimated to be 1-2g. In vivo outcome: See Nitrobenzene. Poisoning mechanism: see nitrobenzene. Clinical acute poisoning after exposure to trinitrotoluene local skin dyed orange, about a week or so occur in contact dermatitis site, table
structure
is red papules, after the rash after integration and scaling. Most people continue to contact the rash subsided, a few people sick of increase. Short-term inhalation of high concentrations of TNT powder, place in a few days later, cyanosis, chest tightness,
nike air force one low, dyspnea, high-iron hemoglobin blood. 6.2.1 Clinical manifestations of chronic poisoning symptoms showed pale, lips and ears were black and blue Also may be shortness of breath,
air force 1 high, headache, fatigue, and morning vomiting is satisfied by the performance. Clinically divided into the following four types: ① Toxic gastritis: patients anorexia, upper abdominal pain, nausea, vomiting and constipation, and eating nothing. Endoscopy found that simple gastritis. ② toxic hepatitis: exposure and more were more than 3 months occurred in hepatomegaly with tenderness, abnormal liver function. In case of jaundice, poor prognosis. Disengagement, improved rapidly. ③ anemia: anemia, low-pigmented, reticular cells may be associated with increased bilirubin and urine urobilinogen positive, He Enzi bodies were positive, the point-shaped red blood cells increase and so on. Severe cases may progress to aplastic anemia, showed progressive anemia, pancytopenia and bone marrow dysplasia. ④ toxic cataract: the highest incidence rate generally proportional to the incidence and length of service. Individuals can be exposed to high concentrations of incidence of less than one year. Beginning of the lens peripheral ring shadows, with the progression of the disease may appear circular or disc-like central part of turbidity. Distributed in a ring was due to cataract, it has little effect on central vision. 6.2.2 Diagnosis of occupational exposure to trinitrotoluene under the close history of liver disease, blood eye lens to change the situation changes and the exclusion of other diseases caused by these changes, before diagnosis. 6.2.2.1 observed objects: thorough examination according to law, the crystal periphery, with or without point-like shadow, slit lamp examination, lens opacity surrounding a small dot, leather is still transparent; or hepatomegaly in the midclavicular line under the costal margin less than 1.0cm, texture changes and liver function were suspicious; or blood suspicious changes. 6.2.2.2 mild poisoning: two cases with the following. A ring of peripheral Shadow Crystal, turbidity does not exceed the scope of the crystal radius of 1 / 3 or 2 / 3, slit lamp examination, turbidity, fine point gathered together for the sallow, located around the polar subcapsular cortex, the cortex or lower degree of transparency varying depending on the material obstacles; or hepatomegaly of midclavicular line above the rib margin of 1.0cm, and the quality of tough tenderness with abnormal liver function, liver function is normal, hepatomegaly shall comply with ribs 1.5cm; or anemia, blood cells decreased. If only the main changes in the liver or crystals, except for other causes and can can be the appropriate diagnosis of liver disease or toxic trinitrotoluene cataract. 6.2.2.3 Severe poisoning: in mild poisoning, based on one of the following conditions. Cirrhosis: three or crystal damage to the peripheral lens opacity than the radius of 2 / 3 or more, the central part of a dense point-like or discoid opacity, visual acuity and visual field was significantly impaired; or aplastic anemia. 6.2.3 Treatment of proper rest, nutrition, and to symptomatic treatment. 6.2.3.1 Treatment of trinitrotoluene cataract ① treatment by conventional treatment of cataract: the stopping and other eye drops white drops, medicine, such as loquat Ju Di Huang Wan, Dendrobium luminous balls oral, Vitc and VitE oral treatment. ② crystal completely cloudy, could the purposes of cataract extraction, with corrective glasses after surgery, as appropriate, conditions are feasible and intraocular lens implantation. 6.2.3.2 ① treatment of liver diseases from toxic exposure to trinitrotoluene ② symptomatic and supportive therapy: bed rest, eating nutritious foods easy to digest, intravenous glucose supplement and vitamin C; liver drug use, such as the liver is too prime 0.2gtid, VitBco 2 tablets tid, CpA100u intramuscularly qd, CoR10 20mgtid, ATP40mg IM qd. May be necessary, intravenous infusion of GIK or FDP. ③ severe, corticosteroid: hydrocortisone 200-400mg / d intravenously, if necessary, blood and human blood proteins. 6.2.3.3 ① treatment of aplastic anemia from exposure to trinitrotoluene. ② androgen application: Hong Long Knife 2mgtid, 50-100mg of testosterone propionate intramuscularly qd, a course of 3 to 6 months. Note the treatment of liver function. ③ the use of corticosteroids: prednisone 100g tid; intravenous hydrocortisone 200 ~ 300g to reduce bleeding tendency and inhibition of acute toxicity. ④ prevention and control of infection. ⑤ necessary blood transfusions. Conditions when possible bone marrow transplantation. ① to prevent contact with the control process of reform: the mixture of TNT,
air force one high, loading and other processes should be closed, and set to automatic operation of local ventilation. ② comply with the safety operating procedures: to minimize skin contact. ③ regular maintenance: equipment should be regular maintenance, to minimize the concentration of powder and steam. ④ types of rotation: rotate every 1 to 2 years time, can reduce the accumulation of TNT in the body, preventing the development of liver disease. Regular check liver function, hemoglobin, and crystal. Where was abnormal liver function or anemia, combined with the determination of urinary metabolites, timely dismiss them. Employment contraindications various liver diseases, hepatitis B surface antigen carriers, a variety of blood diseases, cataract and lens opacities or severe systemic skin disease who were not engaged in this operation. Guardianship of the physical examination required of Workers Exposed to make pre-employment medical examination; and monitoring of an annual physical examination. Include examinations of internal medicine, ophthalmology comprehensive examination, liver function tests, hepatitis B surface antigen measurement and blood examination. Protection of personal protective and operational wear tight sleeve industrial work clothes, wash hands thoroughly after work and shower. Available with 10% potassium sulfite soap. Potassium sulfite case of TNT into the red as red can wash contaminated skin that has been cleared. 9:1 Alcohol can also be immersed in sodium hydroxide solution of cotton towels, wash, who does not appear yellow. Testing the same principle can also be used overalls cleaning level. Standard health standards: China workshop maximum allowable concentration of air 1mg/m3 (skin). National standards for diagnosis of occupational diseases: chronic trinitrotoluene poisoning diagnosis of occupational standards and principles of GB3231-82, diagnosis of occupational standards and principles of GB11512-89. Emergency treatment and disposal methods a leakage contingency isolation leakage polluted area, located around the warning signs, cut off the source of fire.
