Diagnostic Criteria of Chemical Skin Burns ICS 13.100 C60 GBZ People's Republic of China National Occupational Health Standards Occupational chemical skin burns diagnostic criteria Released in.2002-04-08 2002-06-01 Implementation Issued by the Ministry of Health of the People's Republic of China

Foreword

Article 4.1 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 16371-1996 inconsistent with this standard, the standard shall prevail. In the professional activities, due to improper protection or accidents, some high temperature or room temperature chemicals directly contaminated operators Skin, irritation to the skin, corrosion, and chemical stress caused by acute skin damage, in order to early diagnosis and positive To deal with, to protect the health of the operator, the development of this standard. Appendix A to this standard is an informative appendix, Appendix B, C, D, E 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 Shanghai Chemical Industry Occupational Disease Prevention Hospital, Shanghai Second Medical University Affiliated Ruijin Hospital is responsible for drafting, Shanghai Second Military Medical University, Shanghai Institute of Occupational Health and Occupational Disease Prevention and Control, Tianjin Occupational Disease Prevention and Control Hospital, Beijing Jishuitan Hospital, Chongqing Third Military Medical University, Lanzhou Petrochemical Company Hospital, Jilin Chemical Company Hospital to participate in the drafting. This standard is interpreted by the Ministry of Health of the People's Republic of China. Occupational chemical skin burns diagnostic criteria Chemical skin burns are caused by normal or high temperature chemicals directly on skin irritation, corrosion and chemical reactions Acute skin damage, may be associated with eye burns and respiratory injury. Some chemicals can be absorbed through the skin, mucous membrane poisoning.

1 Scope

This standard specifies the diagnostic criteria and principles of occupational chemical skin burns. This standard applies to the diagnosis and treatment of occupational chemical skin burns.

2 diagnostic principles

2.1 According to the skin after exposure to a chemical caused by acute skin damage, such as erythema, blisters, Jiao Chi, can be diagnosed as The chemical burns. 2.2 Some chemicals such as yellow phosphorus, phenol, hot barium chloride, cyanide, acrylic eyes, carbon tetrachloride, aniline, etc. can also be skin Skin, mucous membrane absorption, the merger of the chemical poisoning.

3 Diagnostic and grading standards

3.1 mild burns total area of 10% in the following degree of burns. 3.2 moderate burns in the total area of 11% to 30% or Ⅲ degree of 10% in the burns. The 3.3 Severe burns with any of the following, can be diagnosed as severe burns. a) the total area of 31% to 50% or Ⅲ degree in 11% to 20% of the burns; b) burns with a total area of < 30% with severe eye, esophagus or upper respiratory tract injury; c) head and face, neck, hands, joints and other special parts of the burns, although the smaller area, but caused by dysfunction, disfigurement, Disabled person. 3.4 Special burns total area of more than 50% or Ⅲ degree burns more than 20%, accompanied by severe solid organ damage or lower respiratory Road damage.

4 Principles of handling

4.1 Principles of treatment 4.1.1 quickly removed from the scene, take off the chemicals contaminated clothing, gloves, shoes and socks, etc., and immediately with a lot of mobile water thoroughly Bottom rinse. Flushing time is generally 20 ~ 30 min. The rinse time should be prolonged after burned with alkaline substances. Should pay special attention to the eye And other special parts such as head and face, hand, perineal rinse. Burn the wound after the water rinse treatment, if necessary, can be reasonable Neutralization treatment. 4.1.2 chemical burns wounds should be completely debridement, cut blisters, remove necrotic tissue, the depth of the wound should be immediately or early cut (Cut) scab skin graft or delayed skin graft. 4.1.3 Chemical burns are the same as conventional treatments for thermal burns. 4.1.4 at the same time eye, respiratory injury or chemical poisoning, please specialist treatment. 4.2 Other processing 4.2.1 functional parts of the burns, resulting in facial features, sports systems or organs of severe dysfunction, as appropriate arrangements for work or rest. 4.2.2 non-functional parts of the burns, no sequelae after cure, can return to the original job.

5 Use the instructions of this standard correctly

See Appendix A (informative).

Appendix A

(Informative) Correctly use the instructions in this standard A.1 chemical skin burns are high temperature or room temperature chemicals directly on the skin irritation, corrosion and chemical reaction caused by heat Of acute skin damage. Does not include fire damage, water burns and frostbite. A.2 Ask the history of exposure and conduct a field investigation, should pay attention to the nature of chemicals, exposure dose, exposure concentration, contact time, Contact, labor protection, personal hygiene, season and rinse time and other factors on the occurrence and development of the disease. A.3 chemical skin burns should pay attention to burn area, degree and location. Burn area calculated by the new nine points method (I degree burns Regardless of area). Estimate the degree of burns and decide to cut the scab before surgery, be sure to pay attention to Ⅲ degree alkali burn wounds and Ⅱ degree burns scabs The morphological characteristics. A.4 The diagnosis of chemical skin burns is based on clinical symptoms, signs, and occupational exposure to skin burns. The close causal relationship between the exhibitions. This standard is based on the national burn meeting grading standards for diagnosis and classification. Some chemicals Caused by burn area is not large, but because of local tissue damage and disability, should also be severe burns. A.5 Some chemical skin burns may be associated with eye burns, respiratory burns or chemical poisoning, some poisons such as cyanide, Carbon tetrachloride, aniline or hot barium chloride and other burns can be combined with poisoning or delayed poisoning, should pay special attention, and according to the corresponding Chemical poisoning or burns diagnostic criteria and treatment principles for diagnosis and treatment.

Double upper limb area of 18% (of which the front and rear side of the arm of each 2%, 1.5% of the forearm, palm of the hand, 1% of the back). Trunk area of 27% (of which the front and rear side of the 13%, perineum 1%). Buttocks area of 5%. A total of 41% of the lower limb area (including the front and rear side of the thigh 5%, calves 3 .5%, dorsal, Plantar surface of 1.75%). Site area,% neck Double upper limbs trunk Both lower limbs 9 (1 × 9) 18 (2 × 9) 27 (3 × 9) Includes perineum 1 46 (5 × 9 1) Appendix C.
