Acute formaldehyde poisoning is a systemic disease caused by exposure to high concentrations of formaldehyde vapor, with damage to the eyes and respiratory system as the main symptoms. 1 Diagnostic principles
Acute formaldehyde poisoning can only be diagnosed based on the rapid onset of disease after short-term occupational exposure to high concentrations of formaldehyde vapor, combined with a comprehensive analysis of clinical symptoms, signs and chest X-ray manifestations, and the exclusion of similar diseases caused by other reasons. 2 Diagnosis and classification criteria
2.1 Formaldehyde irritation reaction
It manifests as transient eye and upper respiratory tract irritation symptoms, such as eye stinging, tearing, sore throat, chest tightness, cough, etc. Chest auscultation and chest X-ray show no abnormal findings:
2.2 Mild poisoning
There are systemic symptoms such as blurred vision, dizziness, headache, fatigue, etc., and the conjunctiva and pharynx are obviously congested. Chest auscultation shows coarse breath sounds or dry rales. After comprehensive analysis, it can be diagnosed as mild poisoning. Chest X-ray examination shows no positive findings except for enhanced lung texture. 2.3 Moderate poisoning
Based on the comprehensive analysis of the following manifestations, it can be diagnosed as moderate poisoning: persistent cough, hoarseness, chest pain, difficulty breathing, scattered ten and wet rales on chest auscultation, which may be accompanied by increased body temperature and increased white blood cell count.
h. Chest X-ray examination shows scattered spots or patches of shadows 2.4 Severe poisoning
If one of the following conditions exists, severe poisoning can be diagnosed: laryngeal edema and asphyxiation,
pulmonary edema;
convulsion,
shock.
3 Treatment principles
Quickly leave the scene, lie still, keep warm, and breathe when necessary 3.1
After inhaling a large amount of formaldehyde vapor in a short period of time, if there is an upper respiratory tract irritation reaction, observe for at least 24 hours, and avoid activities that aggravate the condition. 3. 2 Carefully observe to prevent edema. If necessary, glucocorticoids can be used early. 3. 3 Symptomatic treatment, treatment of complications, and prevention of infection. Approved by the Ministry of Health of the People's Republic of China on February 22, 1988, and implemented on September 1, 1988

GE 879188
For mild to moderate poisoning, after a short rest and treatment, they can generally resume their original work after recovery. However, those with a physical condition of overtraining and those with severe poisoning should be transferred after recovery.
5 Requirements for health examination
5.1 Persons working with formaldehyde should undergo a pre-employment physical examination and a regular physical examination every two years. 5.2 During the physical examination, internal medicine, ENT, dermatology, chest X-ray or microfilm examinations and other related examinations must be conducted. Units with conditions may conduct lung function tests.

Instructions for the correct use of standards
(reference)
A.1 This standard applies to acute formaldehyde poisoning. Other aldehyde compounds, especially low molecular weight aldehydes and open chain aldehydes, such as acetaldehyde, ene aldehyde, etc., can also be used in reference to this standard.
A.2 The disease is mainly characterized by respiratory system lesions, and may also be accompanied by symptoms of the eyes and other systems and an increase in the total number of white blood cells, which seems to be inconsistent with the severity of the poisoning. Therefore, the poisoning diagnosis and classification standard is mainly based on respiratory system symptoms, signs and chest X-ray examination. If the clinical manifestations do not match the chest X-ray signs, the diagnosis should be made based on the main indicators with obvious changes. A.3 Formaldehyde can cause occupational asthma and occupational skin diseases. Both are allergic diseases. This standard is not included. Additional instructions:
This standard was proposed by the Occupational Disease Diagnosis Standard Promotion Subcommittee of the National Health Standards Technical Committee. This standard was drafted by Jilin Provincial Institute of Labor Hygiene and Occupational Diseases, Shanxi Medical College Health Department, Heilongjiang Provincial Institute of Labor Hygiene and Occupational Diseases, the Seventh Institute of the Ministry of Nuclear Industry, and Hengshui District Health and Epidemic Prevention Station. This standard was interpreted by the Institute of Labor Hygiene and Occupational Diseases of the Chinese Academy of Preventive Medicine entrusted by the Ministry of Health.
