Article 5.1 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 GB7798-1987 is inconsistent with this standard, this standard shall prevail. Hexavalent chromium compounds such as chromic anhydride, chromic acid, chromate and dichromate are widely exposed in electroplating operations. If the protection is not appropriate, the operator may suffer from chromium nose diseases mainly characterized by erosion, ulceration and perforation of the nasal septum mucosa. This standard is formulated to correctly diagnose and treat nasal damage in the early stage and protect the health of workers. 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 is drafted by the Occupational Prevention Institute of Nanjing Chemical Industry Company. This standard is interpreted by the Ministry of Health of the People's Republic of China. ..comDiagnostic Standard for Occupational Chromic Rhinitis
GBZ12-2002
Nose damage caused by hexavalent chromium compounds such as chromic anhydride, chromic acid, chromate and dichromate is called chromic rhinitis. 1 Scope
This standard specifies the diagnostic standards and treatment principles for occupational chromic rhinitis. This standard applies to occupational nasal damage caused by hexavalent chromium compounds. 2 Normative References
The clauses in the following documents become the clauses of this standard through reference in this standard. For all dated referenced documents, all subsequent amendments (excluding errata) or revisions are not applicable to this standard. However, parties to 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 Skin Diseases (General Principles) Based on the occupational history of close contact with hexavalent chromium compounds and relevant clinical manifestations, excluding nasal damage caused by other reasons, combined with the investigation of labor hygiene in the working environment, the diagnosis can be made. 4 Diagnostic Criteria
Patients with chromium rhinitis may have symptoms such as runny nose, nasal congestion, nasal dryness, nasal burning pain, hyposmia, and signs such as congestion, swelling, dryness or atrophy of the nasal mucosa. Anyone with any of the following nasal signs can be diagnosed with chromium rhinitis. a) Erosion of the nasal septum mucosa, in a few cases, erosion of the turbinate mucosa: b) Ulceration of the nasal septum mucosa;
Perforation of the nasal septum cartilage.
Treatment Principles
5.1 Treatment Principles
Symptomatic treatment is the main treatment. Sodium thiosulfate solution or lysozyme preparation can be applied topically: For patients with nasal septum perforation, nasal septum repair can be performed if necessary.
5.2 Other treatmentsbzxz.net
5.2.1 Patients with severe nasal mucosal erosion can temporarily leave chromium work: Patients with nasal mucosal ulcers should temporarily leave chromium work, and those who fail to recover after long-term treatment can consider transferring away from chromium work. 5.2.2
5.2.3 Anyone with nasal septum perforation should be transferred away from chromium work. ..comInstructions for the correct use of this standard

Instructions for the correct use of this standard
A.1 This standard only applies to occupational nasal damage caused by hexavalent chromium compounds. Chromium damage to the skin can be treated with reference to GBZ18.
2Nasal septum perforation can also be caused by fluoride salts, table salt, vanadium pentoxide, etc.; or by syphilis, tuberculosis, trauma, etc. Therefore, the diagnosis should be made in combination with the pre-employment physical examination data, the patient's history of exposure to toxic substances and the investigation of the working environment for differential diagnosis.
