According to the "People's Republic of China Occupational Disease Prevention Law" to develop this standard. Since the implementation of the standard date, the original standard GB 7807-1987 inconsistent with this standard, the standard shall prevail. Occupational photosensitizing dermatitis caused by photosensitizers occupies a certain proportion in occupational skin diseases. Disease, recurrent, and often secondary diffuse pigmentation, affecting the physical and mental health of workers. To protect the health of occupational contacts, Effective prevention and treatment of occupational skin disease, the development of this standard. Appendix A to this standard is an informative appendix and Appendix B is a normative appendix. This standard is proposed and centralized by the Ministry of Health of the People's Republic of China. This standard by the Chinese Center for Disease Control and Prevention Occupational Health and Poison Control, Shanghai Second Medical University, Shanghai skin Skin disease STD Hospital, Shandong Province, Labor and Health Occupational Disease Prevention and Control Institute, Changchun City, the second hospital is responsible for drafting. This standard is interpreted by the Ministry of Health of the People's Republic of China. Diagnostic criteria for occupational photosensitive dermatitis Occupational photosensitizing dermatitis refers to the movement of light in contact with light-sensitive substances (such as coal tar pitch, chlorpromazine and its intermediates, Benzene around the ketone, etc.), and by the sunlight caused by skin inflammatory response.1 ScopeThis standard specifies the diagnostic criteria and principles of occupational photosensitive dermatitis. This standard applies to the diagnosis and treatment of occupational photosensitive dermatitis.2 diagnostic principlesAccording to a clear history of occupational exposure to photosynthetic substances, before the onset (or onset), with sun exposure history, clinical manifestations; Refer to the operating environment survey, the same kind of disease situation; need to be combined with light patch test to conduct a comprehensive analysis, excluding other non Occupational factors caused by skin diseases, can be diagnosed.3 diagnostic criteria3.1 Occupational phototoxic dermatitis Skin lesions were localized erythema, burning sensation or pain. Severe edema and blisters or conjunctivitis may occur Symptoms such as headache, dizziness, fatigue, thirst, nausea and so on. Those who have the following conditions can be diagnosed. 3.1.1 before the onset of a certain amount of photosynthetic substances occupational exposure history, and subject to a certain intensity and time of the sun Shoot 3.1.2 skin lesions occur in contact with the photosensitive material and subject to sunlight. 3.1.3 isoforms, under the same conditions most people get sick. 3.1.4 skin lesions originated within a few hours after exposure to sunlight. 3.1.5 from the contact with light-sensitive substances or to avoid sunlight, the dermatitis subsided faster, local can have varying degrees of pigmentation With 3.1.6 If necessary, do light spot test, was sunburn-like reaction. 3.2 occupational light change should (allergies) dermatitis Lesions for the edema of erythema, the edge is not clear, there are small pimples or blisters. There are different degrees of itching. Has the following Conditions can be diagnosed. 3.2.1 before the onset of occupational photosensitivity material exposure history, and by sunlight. 3.2.2 lesions began to occur in the contact area, after the spread to the surrounding, spread to other parts of the body. 3.2.3 isoform, under the same conditions only a few people onset. 3.2.4 lesions began to contact the photosensitive material and the sun after 5 to 14 days or longer, sensitized and then contact in general 24 hours Within the disease. 3.2.5 course of delay, in the disengagement, the general need about two weeks to cure. Sometimes for several months, the general after the general no obvious The pigmentation. 3.2.6 If necessary, do light patch test, was eczema-like reaction.4 Principles of handling4.1 Principles of treatment 4.1.l timely removal of pathogens on the skin. 4.1.2 Temporarily avoid contact with photosensitive substances and sunlight. 4.1.3 according to the disease according to the principle of treatment of acute dermatitis symptomatic treatment. 4.2 Other processing 4.2.1 serious phototoxic dermatitis, during treatment can be given according to the condition of the appropriate rest. After healing, improve the labor bar And to enhance personal protection or to avoid operating in the sun can be engaged in the original work. 4.2.2 severe light allergic dermatitis, recurrent hair, in addition to the necessary rest, treatment, may consider changing the type of work, Avoid contact with light-sensitive substances.5 Use the instructions of this standard correctlySee Appendix A (informative), Appendix B (normative).Appendix A(Informative) Correctly use the instructions in this standard A.1 This standard applies only to occupational photosensitive dermatitis. Diagnosis should pay attention to occupational contact dermatitis and a variety of non-professional Sexually sensitive skin disease phase identification. A.2 has a clear history of exposure to occupational light-sensitive substances and has a history of sun exposure before (or at the time of onset) Breaking the important basis. The photoreceptor test can be distinguished from the general contact dermatitis and distinguish it from phototoxic dermatitis or Light allergic dermatitis. A.3 Phototoxic dermatitis and allergic dermatitis have different clinical symptoms, treatment principles (including labor ability identification) when Be differentiated. But some light-sensitive substances can not only have the role of phototoxic and light sensitization, difficult to distinguish between clinical symptoms, Do not force classification, can be collectively referred to as occupational photosensitive dermatitis. Treatment principles are treated by light allergic dermatitis. A.4 some light-sensitive substances in addition to cause light-sensitive dermatitis, but also can cause contact dermatitis, the principle of treatment in accordance with the disease Nature as appropriate. A.5 common photosensitious substances are. coal tar, coal tar pitch, acridine, anthracene, phenanthrene, phenylephrine, benzene around the anthrone, Anthraquinone dyes, chlorpheniramine, chlorpromazine, halogenated salicylanilide, sulfadiazine, promethazine and the like.Appendix B(Normative appendix) Spotting test B.1 Light source General treatment with mercury gas quartz lamp or water-cooled quartz lamp. The distance from the light source to the skin is 50cm. B.2 method a) The minimum erythema (MED) of the patient was measured by light; b) with a suspicious pathogenic substance in the back of the patient for three closed paste test; c) After 24 hours, remove the two patches and place one of them with sub-erythema (slightly lower than MED). another With the addition of ordinary window glass filter of ultraviolet radiation. Time for the MED 20 to 30 times. The third place in the removal caused After the disease is immediately covered with a dressing, avoid any light exposure, used as a control; d) 24,48,72 hours after irradiation observation. the sub-erythema irradiation occurred in the sun-like reaction of light poisonous Sexual response. In the window glass filter UV exposure occurs eczema-like reaction for the photoresponse response. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GBZ21-2006_English be delivered?Answer: Upon your order, we will start to translate GBZ21-2006_English as soon as possible, and keep you informed of the progress.
