GBZ 48-2002 Metal fume fever diagnostic standard

This standard specifies the diagnostic criteria and treatment principles for metal fume fever. This standard applies to metal fume fever caused by zinc smelting, zinc alloy casting, zinc white manufacturing, galvanizing, zinc spraying, zinc welding and other zinc workers. It is also applicable to metal fume fever caused by metal oxide fumes produced during the smelting and casting of minerals such as copper, silver, iron, cadmium, lead and arsenic.

Article 4.1 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 the original standard GB11515-1989 is inconsistent with this standard, this standard shall prevail. In the process of smelting, casting and using minerals containing zinc, copper, picks, etc., if the protection is not appropriate, the operator may inhale the newly generated metal oxide fumes and develop metal fume fever, which is mainly characterized by a sudden increase in body temperature and an increase in the number of white blood cells in the blood. This standard is formulated to facilitate early diagnosis and treatment and protect the health of the operator. 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 the Hunan Provincial Institute of Labor Health and Occupational Disease Prevention and Control, and Beijing Center for Disease Control and Prevention, Luoyang Occupational Disease Prevention and Control Institute, and Lanzhou Baiyin Company Industrial Labor Health Research Institute participated in the drafting. This standard is interpreted by the Ministry of Health of the People's Republic of China Metal Fume Fever Diagnostic Standard
GBZ48-2002
Metal fume fever is a systemic disease with typical sudden rise in body temperature and increase in blood leukocyte count as the main manifestations caused by inhalation of newly generated metal oxide fumes. 1 Scope
This standard specifies the diagnostic criteria and treatment principles for metal fume fever. This standard applies to metal fume fever of zinc workers in zinc smelting, zinc alloy casting, zinc white manufacturing, galvanizing, zinc spraying, zinc welding, etc. It is also applicable to metal fume fever caused by metal oxide fumes generated during the smelting and casting of copper, silver, iron, cadmium, lead, arsenic and other minerals.
2 Diagnostic principles
Based on the occupational exposure history of metal oxide fumes, typical sudden clinical symptoms, special temperature changes and increased white blood cell count, reference to the working environment, comprehensive analysis, and exclusion of similar diseases, a diagnosis can be made. 3 Diagnostic criteria
Metal fume fever often develops suddenly within a few hours after exposure to metal oxide fumes. First, dizziness, fatigue, weakness, chest tightness, shortness of breath, muscle pain, joint pain, and then fever, increased white blood cell count, and severe cases are accompanied by chills and shivers. 4
Treatment principles
4.1 Treatment principles
Generally, no special drug treatment is required. For severe cases, symptomatic treatment is given according to the condition. 4.2 Other treatments
After proper rest, the patient can continue to work after recovery and undergo regular reexamination. 5 Instructions for the correct use of this standard

A.1 Scope of application of this standard
Appendix A
(Informative Appendix)
Instructions for the correct use of this standard
This standard applies to metal fume fever caused by zinc workers in zinc smelting, zinc alloy casting, zinc white manufacturing, galvanizing, zinc spraying, zinc welding and other zinc operations. It is also applicable to metal fume fever caused by metal oxide fumes produced during the smelting and casting of minerals such as copper, silver, iron, cadmium, lead and arsenic.
2 Clinical course of metal fume fever
Metal fume fever is acute, with no chronic progression and sequelae. Dizziness, fatigue, weakness, sweating, fever, chills, chills and other symptoms often occur suddenly within 6 to 12 hours after exposure to high concentrations of metal oxide fumes, body temperature rises to above 37.5℃, and blood leukocytosis increases. Symptoms and signs generally disappear within 4 to 24 hours. Leukocytosis usually returns to normal within 4 to 12 hours, except for those with 20x10/L (20,000/mm2) or more, which often lasts for 24 hours. If symptoms, fever and leukocytosis persist, further examination should be conducted to differentiate from related diseases. 3 Differential diagnosis of metal fume fever
Metal fume fever should be differentiated from diseases such as leukoencephalitis, colds, acute tracheitis and acute bronchitis. Metal fume fever has a history of close contact with metal oxide fumes within 12 hours before the onset of the disease; during the onset of the disease, there is a typical rise in body temperature, accompanied by an increase in blood leukocytosis, and the condition can heal itself within one day without special treatment.
