This standard specifies the diagnostic criteria and treatment principles for occupational skin ulcers. This standard applies to the diagnosis and treatment of specific skin ulcers caused by occupational exposure to compounds such as chromium, beryllium, and arsenic. It is not applicable to the diagnosis and treatment of skin ulcers caused by occupational chemical skin burns, burns, frostbite, or other diseases secondary to blood circulation disorders.

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 GB16382-1996 is inconsistent with this standard, this standard shall prevail. Occupational skin ulcer is a special type of skin disease among occupational skin diseases. Although the incidence rate is not high, this ulcer is difficult to heal. If it is not separated from the production environment, it may take several months to heal, causing great pain to the patient. This standard is formulated to protect the health of contacts and effectively prevent and treat occupational skin diseases. 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 Institute of Occupational Health and Poison Control of the Chinese Center for Disease Control and Prevention and the Shanghai Dermatology and Venereology Hospital.
This standard is interpreted by the Ministry of Health of the People's Republic of China. ..comDiagnostic Standard for Occupational Skin Ulcers
GBZ62-2002
Occupational skin ulcers refer to skin ulcers with a relatively specific morphology, typical bird's eye shape, and a relatively chronic course, caused by direct contact with certain chromium, beryllium, arsenic and other compounds during production labor, such as chromium ulcers (chromium sores) and beryllium ulcers. 1 Scope
This standard specifies the diagnostic criteria and treatment principles for occupational skin ulcers. This standard is applicable to the diagnosis and treatment of specific skin ulcers caused by occupational contact with chromium, beryllium, and other compounds, and is not applicable to the diagnosis and treatment of skin ulcers caused by occupational chemical skin burns, burns, frostbite, etc. or other secondary blood circulation disorders.
2 Diagnostic principles
Diagnosis can only be made based on a clear history of occupational contact, special skin manifestations, combined with the survey data of the work environment and labor hygiene, and by excluding other similar skin damage. 3 Diagnostic criteriabZxz.net
The skin lesions are mostly localized edematous erythema or papules at the beginning, followed by the center evolving into light gray or gray-brown necrosis, and ulcerated within a few days, surrounded by a red halo. Then the ulcers gradually rise above the skin surface. Typical ulcers are mostly round, with a diameter of about 2 to 5 mm, and often have a small amount of secretions on the surface, or covered with gray-black scab, and surrounded by a 2 to 4 mm wide, solid dark red embankment-like protrusion, making the entire skin lesion look like a bird's eye. During the recovery process, the inflammation gradually subsides, the ulcer becomes lighter, shrinks, and heals, and finally the embankment-like protrusion gradually flattens, leaving a mild diamond-shaped scar. If contact continues, the ulcer is difficult to heal, and the course of the disease can last for several months or even more than a year. The ulcer may have mild tenderness; the pain is generally not obvious, but it may worsen after contact with strong irritants. 4 Treatment principles
4.1 Treatment principles
Remove pathogens remaining on the skin in a timely manner; clean the wound surface and treat the symptoms. 4.2 Other treatments
Occupational skin ulcers generally do not affect labor. Under the condition of strengthening protection, you can continue to do your original work. Instructions for the correct use of this standard
See Appendix A (Informative Appendix).
..comAppendix A
(Informative Appendix)
Instructions for the correct use of this standard
A.1 Common pathogens of occupational skin ulcers include hexavalent chromium compounds such as chromic anhydride, chromic acid, chromate, and dichromate, and soluble beryllium compounds such as beryllium fluoride, beryllium chloride, and beryllium sulfate. They are often seen in industries such as the production and use of chromium, beryllium smelting and their compounds (such as leather and chrome plating).
A.2 Before the onset of occupational skin ulcers, there is often a history of local skin damage, such as dermatitis, insect bites, scratches, and various traumas. A.3 Occupational skin ulcers are often found in direct contact areas such as fingers, backs of hands, forearms, and calves. A.4 Common skin ulcers caused by chromium and beryllium compounds are mostly bird-eye-shaped, sometimes linear or irregular due to trauma, and a few caused by other pathogens often have no obvious embankment-like ridges on the edges. A.5 For skin ulcers caused by metal compounds, the metal content in the blood and urine can only indicate the degree of contact and cannot be used as a basis for the diagnosis of occupational skin ulcers.
A.6 When diagnosing this disease, a cause diagnosis should be made, and the pathogen should be indicated in brackets after the name of the disease, such as "occupational skin ulcer (caused by potassium dichromate)".
A.7 This disease should be distinguished from ulcers caused by chemical skin burns and impetigo (deep pustule). A.8 Occupational skin ulcers are currently treated mainly with symptomatic treatment. During treatment, emphasis is placed on repeated cleaning of the wound surface and covering with impermeable dressings to fix it. This can isolate pathogens, improve drug efficacy, and allow treatment to be carried out without leaving production conditions. After the damaged skin comes into contact with pathogens, it should be immediately rinsed thoroughly with running water, and the wound surface should be protected to prevent ulcer formation. ..com
