Foreword

Article 5.1 of this standard is recommended and the remainder is mandatory.

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 16375-1996 inconsistent with this standard, subject to this standard.

Occupational acne is a common occupational skin disease, the incidence rate after occupational exposure to dermatitis. For the protection of occupational contacts the health and 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 of occupational health and poisoning control is responsible for the drafting of the Shanghai Dermatology STD Hospital, Shanghai Second Medical University, Shandong Province, Labor and Health Occupational Disease Prevention and Control Research Institute, Changchun City, the second hospital to participate in the drafting.

This standard is interpreted by the Ministry of Health of the People's Republic of China.

Occupational acne diagnostic criteria Occupational acne refers to the production of labor in contact with mineral oil or some halogenated hydrocarbons caused by skin follicles, sebaceous gland Chronic inflammatory damage. By the coal tar, shale oil, natural oil and its high boiling fractionation products and asphalt caused by oil acne called;

Caused by certain halogenated aromatic hydrocarbons, polychlorophenol and polyvinyl chloride pyrolysis, etc. called chlorinated acne.

1 Scope

This standard specifies the diagnostic criteria and principles of occupational acne.

This standard applies to the diagnosis and treatment of occupational acne.

GBZ 18 diagnostic criteria for occupational dermatosis (general)

3 Diagnostic principles

According to a clear history of occupational exposure, the unique clinical manifestations and the incidence of parts; reference service age, age of onset, operating environment survey and epidemiological survey data; combined with the dynamic observation of the disease, a comprehensive analysis, excluding acne vulgaris and non-occupational exogenous Acne can be diagnosed.

6 Correct use of the description of this standard

See Appendix A (informative), Appendix B (normative).

Appendix A

(Informative)

Correctly use the instructions in this standard A.1 This standard applies only to the diagnosis and treatment of oil acne and chlorinated acne caused by occupational causes. Other illnesses and occupational contacts Clear cause and effect of acne, according to the provisions of GBZ 18 principles, with reference to this standard for diagnosis and treatment.

A.2 Occupational acne is a chronic skin damage, the onset of latency depends on the nature of the contact with the disease, the dose, the role of time and individual quality and other comprehensive factors. So in the standard only to have a clear longer period of professional contact history, but not with a Body period. Diagnosis can be based on a comprehensive role, a comprehensive consideration of the decision.

A.3 Occupational acne is a multifactorial disease, acne caused by a variety of pathogens, the clinical manifestations are not the same. For ease of control, According to the main pathogen and clinical manifestations are similar, summarized as oil acne and chlorine acne two categories. Both are just classified, not fixed of the rash, the diagnosis should be unified diagnosis of occupational acne. For ease of handling, if necessary, indicate pathogens in brackets, for example Occupational acne (caused by XX).

A.4 oil acne before the onset of a clear longer contact with tar (or crude oil), asphalt and high boiling fraction of mineral oil (such as wood Oil, oil and various lubricants).

Chlorine acne before the onset of a clear longer contact with polychlorobenzene, polychlorinated naphthalene, polychlorophenol, certain brominated aromatic hydrocarbons and polyvinyl chloride the history of pyrolysis.

Oil acne and acne vulgaris occur in the site of frequent contact with the disease; any age can be disease; the same working conditions of the same type of work may have more similar patients; from the contact with the pathogen after a certain period of time, the condition can be reduced or cured, but the cyst is not easy to subside;

Repeated contact with the disease after a certain period of time, the condition can be aggravated or relapse.

A.5 Diagnosis of occupational acne should be identified with the usual acne. Acne acne has its fixed predilection site (face and neck, chest, back, shoulder) and good age (15 to 25 years), and occupational acne can occur at any age and any contact parts, which in the differential diagnosis There's important meaning. The occurrence of young workers in the work of acne, such as lesions is limited to the face, then identify it is occupational acne or Acne vulgaris have some difficulties; if the limbs, scrotum, etc. at the same time there are lesions, you can clearly diagnose occupational acne.

A.6 Chlorine Acne is an acne that is caused by certain halogen compounds, which are mainly aromatic compounds of chlorine and bromine, pure chlorine and Bromine does not cause acne. Acne compounds are mainly polychlorinated naphthalene, polybrominated naphthalene, polychlorinated biphenyls, polybrominated biphenyls, polychlorobenzene, polychlorophenol Wait. Some chlorinated aromatic hydrocarbons in addition to skin contact, the inhalation or intake can lead to chlorine acne, such as polychlorinated biphenyl poisoning when the skin appears acne Sore rash, in this case should first deal with systemic poisoning.

A.7 Occupational contraindications require sebum spillage or severe acne patients should not engage in contact with acne work, is taking into account acne and sebum secretion have a certain relationship, according to the physical arrangement of work, may reduce the incidence, but not absolute, so the already the industry can not use this as the basis for changing jobs.

Appendix B

(Normative appendix) the difference between occupational acne and acne vulgaris

Table B1

The main difference points are acne acne acne acne acne acne Age of onset 15 to 25 years old 30 years old rare any age can be the incidence of any age can be disease Incidence of the surface of the neck, chest and back, shoulder contact parts can be disease, especially by oil Baptist parts of the friction, common in the surface Neck, limbs stretch, abdomen, buttocks and overcast Capsule and so on Contact parts can be disease, more common in the eye Outside the lower part of the zygomatic, around the ear, chest, Back, buttocks and external genital area Clinical manifestations of acne, inflammatory papules, folliculitis, pustules, Nodules, cysts, blackhead acne rare Pores to expand, hair follicle mouth, hair fold Broken, inflammatory pimples, blackheads, nodules, Cysts. Often complicated with verrucous vegetation Blackhead acne, hair follicle mouth, millet mound Rash, grass yellow cysts, inflammatory papules less Disease changes Skin lesions vary with age, with contact There is no significant relationship between oil and halogen compounds Independent of age, disengagement After a certain period of time, the skin lesions can be improved to recovery More, to restore contact with recurrence
