What harm does frequent contact with diesel have to human body?

Mild poisoning is now in a state of excitement or drunkenness, euphoria, facial flushing, followed by lethargy, headache, dizziness, nausea, vomiting, chest tightness, stumbling gait and so on. , and may have mild symptoms of mucosal irritation. 2, severe poisoning can appear blurred vision, tremor, shallow and fast breathing, ventricular arrhythmia, convulsions, delirium and coma. In a few serious cases, respiratory and circulatory failure and ventricular fibrillation may occur. 3. In addition to systemic poisoning, oral cavity, throat, esophagus and gastric mucosa all have irritation after taking benzene by mistake, and even cause pneumonia and collapse. Adult oral administration of 1.5m 1 can be fatal. 4, benzene liquid inhalation in the lungs, can cause pulmonary edema and pulmonary hemorrhage. Occupational acute benzene poisoning refers to a systemic disease characterized by central nervous system inhibition caused by workers inhaling large doses of benzene vapor in a short period of time during occupational activities; Occupational chronic benzene poisoning refers to a systemic disease with hematopoietic system damage as the main manifestation caused by workers' long-term exposure to benzene vapor in occupational activities. Diagnosis: 1, diagnostic criteria This standard specifies the diagnostic criteria, diagnostic writing format and treatment principles of occupational benzene poisoning. This standard is applicable to poisoning caused by exposure to benzene in occupational activities. This standard can be used for benzene poisoning caused by exposure to industrial toluene, xylene and other chemicals containing benzene. This standard can also be used for the diagnosis of benzene poisoning caused by exposure to benzene in non-professional activities. 2. Diagnostic principles The diagnostic basis of acute benzene poisoning is that a large amount of high-concentration benzene vapor is inhaled in a short period of time, the clinical manifestations are conscious, and the changes in central nervous system function caused by other diseases can be ruled out before acute benzene poisoning can be diagnosed; According to the degree of consciousness disorder, it is divided into mild and severe. The diagnosis of chronic benzene poisoning is based on the occupational history of long-term close contact with benzene. The main clinical manifestations are hematopoietic inhibition and abnormal proliferation. The diagnosis of chronic benzene poisoning can only refer to the investigation of working environment and the measurement data of benzene concentration in the air on the spot, and exclude the hemogram changes caused by other reasons. Chronic benzene poisoning can be divided into three levels according to the series and degree of blood cell involvement and whether there is malignant transformation. 3. Diagnostic classification: 3.1; Acute benzene poisoning: 3.1.1; Acute mild poisoning: dizziness, headache, nausea, vomiting, excitement, stumbling gait and other drunken States may occur after inhaling high-concentration benzene vapor in a short time, which may be accompanied by symptoms of mucosal irritation. The increase of breath benzene, blood benzene and urine phenol can be used as indicators of benzene exposure. 3. 1.2, acute severe poisoning, dysphoria, unconsciousness, coma, convulsion, blood pressure drop and even respiratory and circulatory failure after inhaling high concentration benzene vapor. The measured values of breath benzene, blood benzene and urine phenol increased, which can be used as indicators of benzene exposure. 3.2, chronic poisoning 3.2. 1, observation object The blood test of benzene-exposed workers found one of the following changes, and there was still no improvement every 1 ~ 2 weeks within three months, and no other reasons could be found, so they could be classified as observation objects. A) The white blood cell count fluctuates between 4 ~ 4.5×109/L (4000 ~ 4500/mm3); B) The platelet count fluctuates between 60 ~ 80×109/L (60 ~ 80000/mm3); C) The red blood cell count of male is lower than 4×1012/L (4 million /mm3) and that of female is lower than 3.5×10/2/L (3.5 million/mm3); The quantitative hemoglobin of male is lower than 120g/L (12g/DL) and that of female is lower than110g/l (1LG/dl). D) The peripheral blood cell count increases, and naive or abnormal blood cells appear. 3.2.2, chronic mild poisoning every 1 ~ 2 weeks within 3 months, such as white blood cell count is continuously or basically lower than 4× 109/L (4000/mm3) or neutrophil is lower than 2× 109/L (2000/mm3). Often appear dizziness, headache, fatigue, insomnia, memory loss and other symptoms. 3.2.3. Chronic moderate poisoning often has symptoms of chronic mild poisoning, which is prone to infection and/or bleeding. Meet one of the following requirements: a) white blood cell count is lower than 4× l09/l (4000/mm3) or neutrophil is lower than 2× 109/l (2000/mm3), and platelet count is lower than 60× l09/l (60000/mm3); B) White blood cell count is lower than 3× 109/l(3000/mm3) or neutrophil is lower than1.5×109/L (1500/mm3). 3.2.4. Chronic severe poisoning occurs in one of the following situations: a) pancytopenia; B), aplastic anemia; C), myelodysplastic syndrome; D), leukemia. 4, treatment principle 4. 1, acute poisoning should be quickly moved to the scene, poisoned patients should be moved to fresh air, immediately take off clothes contaminated by benzene, wash contaminated skin with soapy water, pay attention to keep warm. The principle of first aid is the same as that of internal medicine, and gastric lavage is given to people who take orally. Glucuronic acid can be given symptomatic and supportive treatment. Pay attention to the prevention and treatment of brain edema. You should stay in bed in the acute stage. Epinephrine should not be used in patients with cardiac arrest. 4.2. There is no specific antidote for chronic poisoning, and the treatment is mainly based on symptomatic treatment of blood diseases caused by hematopoietic system injury. 5, labor ability appraisal 5. 1, acute poisoning recovery period, mild poisoning generally rest for 3 ~ 7 days to go to work. The rest time of severe poisoning should depend on the degree of recovery. 5.2 Once the chronic poisoning is diagnosed, the employee shall be transferred from the job exposed to benzene and other toxic substances. During the illness, work or rest should be arranged according to the illness. 5.2. 1, mild poisoning can generally be engaged in light work or half-day work. 5.2.2, moderate poisoning according to the condition, appropriate arrangements for rest. 5.2.3, severe poisoning all Hugh. 5.3. According to the occupational contraindications, the observed object should be transferred from the benzene operation post. 6. Physical examination requirements 6. 1, physical examination 6. 1. 1. Workers exposed to benzene should undergo employment physical examination, and regular physical examination once a year after work. 6. 1.2. Physical examination items include internal medicine examination, as well as white blood cell count (cell classification if possible), red blood cell count and/or hemoglobin quantification, and platelet count. 6.2, observation object review 6.2. 1, observation object review once every l ~ 3 months, and participate in regular physical examination in the following year. 6.2.2. Laboratory recheck item a), red blood cell count, hemoglobin quantification, white blood cell count and its classification, platelet count and record abnormal blood cells; B) Conduct bone marrow smear and other relevant blood laboratory tests as required. 6.3. Follow-up of chronic poisoning is 6.3. 1, generally L ~ 3 months 1 time. Blood examination items include red blood cell count, hemoglobin quantification, white blood cell count and its classification, platelet count, and record abnormal blood cells. 6.3。 2, blood cell count continues to be abnormal or abnormal shape, bone marrow smear and other related blood laboratory tests should be done. 6.3.3. Follow-up period: Even if the hemogram recovers, it is generally not less than 10 years. 7, occupational contraindications a), pre-employment physical examination, blood test results are lower than the normal reference value; B) Various blood diseases; C), serious systemic skin disease; D) menorrhagia or functional uterine bleeding. The chemical structure of benzene is very stable and it is not easy to degrade under natural environmental conditions. It can cause lasting and serious pollution to soil, water and atmosphere, and its harm to animals, plants and human beings can not be ignored. Therefore, we call on all enterprises related to production, application and transportation in the world to strictly implement the relevant international conventions and industry norms for the production, application, storage and transportation of hazardous chemicals, and constantly improve their processes to reduce and prevent pollution to the natural environment from all sides. That's all. Diesel oil is corrosive, but harmless. However, long-term exposure can easily lead to skin aging. The diesel oil that looks wrong on it is corrosive, but not harmful. However, long-term exposure is easy to cause skin aging and roughness.
