National Occupational Health Standard of the People's Republic of China GBZ27-2002
Diagnostic Criteria of Occupational Solvent Gasoline PoisoningPublished on April 8, 2002
Implemented on June 1, 2002
Ministry of Health of the People's Republic of China
Article 6.1 of this standard is recommended, and the rest are mandatory. This standard is formulated in accordance with the Law of the People's Republic of China on the Prevention and Control of Occupational Diseases. From the date of implementation of this standard, if there is any inconsistency between the original standard GB8785-1988 and this standard, this standard shall prevail. Occupational activities can often cause systemic toxic diseases due to contact with gasoline vapor and liquid. This standard is formulated to protect the health of those who come into contact with it
Appendix A of this standard is an informative appendix.
This standard is proposed and managed by the Ministry of Health of the People's Republic of China. This standard was drafted by Jilin Provincial Institute of Labor Health and Occupational Disease Prevention and Control, Guangdong Provincial Institute of Occupational Disease Prevention and Control, Shaanxi Provincial Center for Disease Control and Prevention, and Xinjiang Autonomous Region Center for Disease Control and Prevention. This standard is interpreted by the Ministry of Health of the People's Republic of China. Diagnostic Standard for Occupational Solvent Gasoline Poisoning
GBZ27-2002
Solvent gasoline poisoning is a systemic toxic disease caused by contact with gasoline vapor or liquid during industrial production or use. Acute poisoning is mainly characterized by neurological or mental symptoms. Inhalation of gasoline into the respiratory tract can cause aspiration pneumonia; chronic poisoning is mainly manifested by neurasthenia syndrome, autonomic dysfunction and toxic peripheral neuropathy. 1 Scope
This standard specifies the diagnostic criteria and treatment principles for occupational solvent gasoline poisoning. This standard applies to the diagnosis of occupational solvent gasoline poisoning: the diagnosis of non-occupational solvent gasoline poisoning can also be implemented as a reference. 2 Normative References
The clauses in the following documents become the clauses of this standard through reference in this standard. For any dated referenced document, all subsequent amendments (excluding errata) or revisions are not applicable to this standard. However, parties reaching an agreement based on this standard are encouraged to study whether the latest versions of these documents can be used. For any undated referenced document, the latest version shall apply to this standard.
3 Diagnostic principles
Diagnostic criteria for occupational acute chemical toxicity nervous system diseases Based on the occupational history of short-term inhalation of high-concentration gasoline vapor or long-term inhalation of gasoline vapor and skin contact with gasoline, clinical manifestations mainly characterized by central nervous system or peripheral nervous system damage, combined with on-site hygiene investigation and determination of gasoline concentration in the air, and excluding similar diseases caused by other causes, a diagnosis can be made. 4 Observation subjects
Symptoms of neurasthenia syndrome and autonomic dysfunction such as headache, dizziness, memory loss, insomnia, fatigue, palpitations, and hyperhidrosis can be listed as observation subjects. 5 Diagnosis and classification standards
5.1 Acute poisoning
5.1.1 Mild poisoning
If any of the following conditions are present, it shall be diagnosed as mild poisoning: a) Headache, dizziness, nausea, vomiting, unsteady gait, blurred vision, irritability; b) Emotional reaction, crying and laughing at will, excitement and restlessness; c) Mild disturbance of consciousness.
5.1.2 Severe poisoning
If any of the following conditions are present, it shall be diagnosed as acute severe poisoning: a) Mild or severe disturbance of consciousness;
Educational pneumonia;
Radioactive respiratory arrest.
5.1.3 Aspiration pneumonia
After gasoline liquid is inhaled into the respiratory tract, one of the following symptoms occurs: a) severe cough, chest pain, hemoptysis, fever, dyspnea, purple and lung rales; b) X-ray examination shows flake or dense mass shadows in the lungs: total white blood cell count and neutrophil granulocytes may increase. 5.2 Chronic poisoning
5.2.1 Mild poisoning
Mild poisoning can be diagnosed if one of the following conditions is met: a) Numbness in the distal extremities, pain and tactile loss in a glove-like or sock-like distribution, accompanied by weakened Achilles tendon reflexes; b) Neuro-electromyography shows neurogenic damage. 5.2.2 Moderate poisoning
In addition to the above symptoms, one of the following conditions is met: a) Muscle strength of the extremities is weakened to 3 degrees or less, and Achilles tendon reflexes are often absent; b) Atrophy of the distal muscles of the extremities (thenar and hypothenar muscles, interosseous muscles). 5.2.3 Severe poisoning
Those who meet any of the following conditions are diagnosed as severe poisoning: a) Toxic encephalopathy, commonly manifested as apathy, slow reaction, loss of memory and calculation ability, etc. b) Toxic psychosis, schizophrenia-like; c) Limb paralysis caused by toxic peripheral neuropathy. 5.3 Skin damage
6 Treatment principles
6.1 Treatment principles
6.1.1 Acute poisoningWww.bzxZ.net
Should leave the scene quickly, remove skin contamination and rest quietly. The first aid principles are the same as those of internal medicine. 6.1.2 Chronic poisoning
Comprehensive symptomatic treatment is carried out according to the condition. The treatment method is the same as that of neuropsychiatry. 6.1.3 Gasoline aspiration pneumonia can be treated with short-term glucocorticoids and symptomatic treatment. 6.2 Other treatments
Observed subjects should undergo a physical examination once a year, with emphasis on the nervous system examination, and neuro-electromyography examination should be performed whenever possible6.2.1
: Acute mild poisoning patients can resume their original work after recovery; severe poisoning patients should be transferred away from gasoline6.2.2
work after recovery; aspiration pneumonia can generally resume their original work after recovery. 6.2.3
Chronic poisoning patients should be transferred away from gasoline work, undergo regular review, and arrange work or rest appropriately according to their condition. For instructions on the correct use of this standard

Appendix A
(Informative Appendix)
Instructions on the correct use of this standard
A.1Solvent gasoline includes 120, 180, 190, 200 and other types of gasoline. A.2 The diagnostic criteria for chronic gasoline poisoning are applicable to the diagnosis of exposure to solvent gasoline poisoning, but not to the diagnosis of leaded gasoline poisoning. The diagnosis of other unleaded power gasoline poisoning can refer to this standard for trial implementation. The diagnostic criteria for acute gasoline poisoning and aspiration pneumonia are applicable to various types of gasoline.
A.3 The main industries that are exposed to occupational solvent gasoline include rubber, leather, shoemaking, rubber products, tires, cleaning of mechanical parts, oil refining and oil depots.
A.4 According to the analysis of survey data, the length of service for occupational chronic solvent gasoline poisoning is generally more than 15 years. However, due to individual differences, gasoline concentration in the air, production environment and personal protection, the length of service for onset can be shorter. A.5 Chronic gasoline poisoning can cause toxic peripheral neuropathy and neurasthenia syndrome. During the physical examination, the deep and shallow sensation of the extremities, the heel and knee tendon reflexes must be repeatedly checked, and neuro-electromyography examinations should be performed. A.6 Neuro-EMG examination is an early objective indicator for diagnosing neurogenic damage. For its operation specifications and the criteria for determining neurogenic damage, please refer to Appendix B of GBZ76.
A.7 For muscle strength grading standards, please refer to Appendix C of GBZ76. A.8 For the grading of consciousness disorders, please refer to Appendix D of GBZ76.
