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 does not apply to the diagnosis and treatment of skin ulcers caused by occupational chemical skin burns, burns, frostbite, or other diseases secondary to blood circulation disorders.

Diagnostic criteria and principles of management of occupational ulcers GB163821996
Occupational skin ulcers refer to skin ulcers with a more specific morphology, typical bird's eye shape, and a more chronic course, caused by direct contact with certain compounds such as chromium, beryllium, and arsenic during production labor, such as chromium ulcers (chrome sores) and beryllium ulcers. 1 Subject content and scope of application
This standard specifies the diagnostic criteria and management principles for occupational skin ulcers. This standard is applicable to the diagnosis and treatment of specific skin ulcers caused by occupational contact with compounds such as chromium, beryllium, and arsenic, and is not applicable to the diagnosis and treatment of skin ulcers caused by occupational chemical skin burns, burns, frostbite, etc. or other skin ulcers secondary to blood circulation disorders. 2. Diagnostic principles
Diagnosis can only be made based on a clear history of occupational exposure, special skin manifestations, combined with the survey data of the work environment and labor hygiene, and by excluding other similar skin lesions.
3 Diagnostic criteria
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 ridge-like protrusion, making the entire skin lesion look like a bird's eye. During the recovery process, the inflammation gradually disappears, the ulcer becomes lighter, shrinks, and heals, and finally the ridge-like protrusion gradually flattens, leaving a mild atrophic 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
Remove pathogens remaining on the skin in a timely manner; clean the wound surface and treat the symptoms. 5 Assessment of labor capacity
Occupational skin ulcers generally do not affect labor. With enhanced protection, you can continue to do your original work. 6 Health examination requirements
Workers engaged in the operation of chromium, beryllium and other compounds should undergo a pre-employment physical examination and a dermatological examination every 1 to 2 years after employment. 7 Occupational contraindications
Severe chronic skin diseases in exposed areas.

Instructions for the correct use of the standard
(reference)
A1 Common pathogens of occupational skin ulcers include hexavalent chromium compounds such as chromic anhydride, chromic acid, chromate, dichromate, and soluble beryllium compounds such as beryllium fluoride, beryllium fluoride, and beryllium sulfate. They are often seen in industries such as chromium and beryllium smelting and the production and use of their compounds (such as leather and chrome plating). A2 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. A3 Occupational skin ulcers are often found in direct contact areas such as fingers, backs of hands, forearms, and calves. A4 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 bank-like protrusions on the edges. A5 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.
A6 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)". A7 This disease should be distinguished from ulcers caused by chemical skin burns and sores (deep pustule). A8 Occupational skin ulcers are currently treated symptomatically. During treatment, it is emphasized that the wound surface should be repeatedly cleaned and covered with impermeable materials to fix it, so that the pathogen can be isolated and the drug efficacy can be improved, and the treatment can be carried out without leaving the production conditions. After the damaged skin comes into contact with the pathogen, it should be immediately rinsed thoroughly with running water, and the wound surface should be protected to prevent the formation of ulcers. A9 The serious chronic skin diseases specified in the occupational contraindications refer to chronic dermatitis, eczema, psoriasis, etc. in exposed parts. Additional remarks:
