GB 8785--88
Systemic toxic diseases caused by contact with gasoline vapor or liquid during industrial production or use. Acute poisoning is mainly characterized by neurological or psychiatric symptoms. Inhalation of gasoline into the respiratory tract may cause aspiration pneumonia. Chronic poisoning is mainly manifested by atlanto-atlantoic syndrome, autonomic dysfunction and toxic peripheral neuropathy. 1 Diagnostic principles
According to the occupational history of short-term inhalation of high-concentration gas sleeve vapor or long-term inhalation of gas pool vapor and skin contact with gasoline, the clinical manifestations of central nervous system or peripheral nerve damage are mainly present, combined with on-site hygiene investigation and determination of gasoline concentration in the air, and similar diseases caused by other causes are excluded before diagnosis can be made.
2 Diagnostic classification
2.1 Observation subjects
Symptoms of neurasthenia syndrome and autonomic nervous system dysfunction such as headache, memory loss, insomnia, fatigue, palpitations, and sweating can be listed as observation subjects.
2.2 Middle-aged and elderly people
2.2.1 Mild moderate
In addition to the above symptoms, those who meet any of the following conditions can be diagnosed as mild moderate distal numbness of the limbs, pain in the distribution of gloves and stockings, tactile hyposensitivity, accompanied by weakened Achilles tendon reflex: neuro-electromyography shows neurogenic damage. b
2.2.2 Moderate poisoning
In addition to the above symptoms, one of the following conditions is present: the muscle strength of the limbs is weakened to 3 degrees or below, and the Achilles tendon reflex often disappears; b.
Atrophy of the distal muscles of the limbs (thenar, hypothenar, and tibialis muscles). 2.2.3 Severe poisoning
Those who meet one of the following conditions are diagnosed as severe poisoning toxic encephalopathy, which is commonly manifested as dull expression, slow reaction, loss of memory and calculation ability, etc. b.
Toxic psychosis, schizophrenia
Toxic peripheral neuropathy caused by paralysis. 2.3 Acute poisoning
2.3.1 Mild moderate poisoning
If any of the following conditions are present, it is considered as mild poisoning: headache, nausea, vomiting, unsteady gait, blurred vision, irritability, emotional reaction, crying and laughing erratically, excitement and restlessness, etc.; mild consciousness disorder.
2.3.2 Severe poisoning
If any of the following conditions are present, it is diagnosed as acute severe poisoning: Moderate or severe consciousness disorder:
Chemical pneumonia:
c. Reflex respiratory arrest.
2.3.3 Aspiration pneumonia
After gasoline liquid is inhaled into the respiratory tract, one of the following symptoms may occur: severe cough, chest pain, hemoptysis, fever, dyspnea, purpura and lung rales; X-ray examination shows flaky or dense mass shadows in the lungs, and the total white blood cell count and neutrophil granulocytes may increase. h.bzxZ.net
2.4 Skin damage
See GB7804-87 "Diagnostic criteria and treatment principles for occupational skin diseases" 3 Treatment principles
3.1 Chronic poisoning
Comprehensive symptomatic treatment is carried out according to the condition. The treatment method is the same as that of neuropsychiatry. 3.2 Acute poisoning
You should leave the scene quickly, remove skin contamination and rest quietly. The rescue principles are the same as those of internal medicine. 3.3 Gasoline aspiration pneumonia can be treated with short-term glucocorticoid therapy and symptomatic treatment. 4 Labor capacity assessment
4.1 The subjects should undergo a physical examination every year, focusing on the nervous system examination, and neuro-electromyography examination as much as possible. 4.2 Chronic poisoning patients should be transferred from gasoline operations, undergo regular review, and arrange work or rest appropriately according to their condition. 4.3 After the mild acute poisoning patients are cured, they can resume their original work; severe After the poisoning patients recover from treatment, they should be transferred away from gasoline operations; after aspiration pneumonia is cured, they can generally resume their original jobs. 5 Health examination requirements
All workers engaged in gasoline operations should undergo a pre-employment physical examination. Gasoline workers should undergo a physical examination every 2 years, including internal medicine, neurology and skin examinations. Those suspected of peripheral neuropathy should undergo a neuro-electromyography examination. 6 Contraindications to occupational drugs
Various organic diseases of the central and peripheral nervous systems or obvious neurosis: a
b Allergic skin diseases or palmar keratosis:
Women should be separated from contact during pregnancy and lactation. GB8785--88

Instructions for the correct use of the label
(reference)
A.1 Solvent gasoline includes types 120, 180.190.200, etc. Gasoline: A.2 The diagnostic criteria for chronic gasoline poisoning are applicable to the diagnosis of poisoning caused by exposure to solvent gasoline, but not to the diagnosis of leaded gasoline poisoning. The diagnosis of other unleaded power gasoline poisoning can be implemented on a trial basis with reference to this standard. The diagnostic criteria for acute gasoline poisoning and aspiration pneumonia are applicable to various types of gasoline.
A,3 The industries that are most exposed to occupational solvent gasoline include rubber, leather making, shoe making, rubber products, tires, cleaning machinery parts, oil refining and oil depots.
A.4 According to the data analysis, the length of service for occupational chronic solvent gasoline poisoning is generally more than 15 years. Due to individual differences, oil concentration in the air, production environment and personal protection, the length of service for onset may be shorter. A.5 Chronic gasoline poisoning can cause toxic peripheral neuropathy and neurasthenia syndrome. During the physical examination, the deep and superficial sensation of the extremities, the heel and knee tendon reflexes must be repeatedly checked. , and neuro-electromyography should be performed. A.6 Neuro-electromyography is an immediate objective indicator for diagnosing neurological damage. For its operation specifications and the criteria for determining neurological damage, please refer to Appendix A of GB486-85 "Occupational chronic carbon monoxide poisoning diagnostic criteria and treatment principles". A.7 For muscle strength grading, please refer to Appendix B of GB4865-85 "Occupational acute carbon monoxide poisoning diagnostic criteria and treatment principles".
