United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS) Joint United States on the Construction of Emergency Goods Standards 3 Terms and Definitions Respiratory sensitizers are substances that cause respiratory sensitization after contact with the skin. 3.2 Skin sensitizers are substances that cause allergic reactions after skin contact. 4 Classification 4.1 Classification of substances 4.1.1 Respiratory sensitizers 4.1.1.1 Hazard categories Substances are classified as respiratory sensitizers (categories): if there is evidence in humans that the substance can cause specific respiratory sensitization and/or there are results from appropriate animal tests. 4.1.1.2 Evidence in humans 4.1.1.2.1 There is evidence, usually based on human experience, that the substance causes specific respiratory sensitization. In this category, allergies usually present as asthma. Other allergic reactions include rhinitis/conjunctivitis and nasal conjunctivitis. Patients with this condition may have clinical features of an allergic reaction, however, an immunological mechanism has not been demonstrated. 4.1.1.2.2 Reference to human evidence When determining the award, consider the source of the infection - the size of the population exposed
- the extent of exposure
4.1.1.2.3 [The evidence for improvement may be a history of exposure to the substance and appropriate clinical data. Other supporting evidence for further confirmation. Order includes:
GB 20595--2006
In vivo immunological tests (e.g., skin scratch tests): - In vitro immunological tests (e.g., biological analysis); - When the immunological mechanism of the sensitization is not clear, other specific allergic reactions can be excluded, such as repeated levels of stimulation, drug-mediated effects:
. Chemical structures related to substances known to cause respiratory allergies: Data obtained from positive bronchial provocation tests on substances based on the generally accepted principles for determining specific allergic reactions. 4.1.1.2.4 Clinical findings from medication history and occupational exposure history to determine the relationship between exposure to specific substances and the development of respiratory allergies: Relevant information should include exacerbating factors in the home and work environment, onset and progression, family history and medical history. The medical history should also include records of other allergies or respiratory diseases since childhood, as well as respiratory history, 4.1.2,5 The results of the bronchial provocation test can provide sufficient evidence for the classification of the allergic substance. However, in practice, many of the tests listed above should be performed first. 4.1.1.3 Animal studies Several animal studies have been conducted to test whether inhalation substances cause sensitization in humans, including: determination of immunoglobulin F (IF) and other immunological parameters such as specific lung responses in mice and guinea pigs.
Note: The mechanism by which substances cause asthma is not fully understood. For protective purposes, these substances are considered respiratory sensitizers. However, if there is sufficient evidence that the substance stimulates bronchial hyperreactivity in humans and causes respiratory symptoms, then the substance is not considered a respiratory sensitizer.
Note 2: There are currently no animal models available for testing inhalation allergy reactions. Under certain circumstances, animals can be used for testing, for example, in mice to test the mechanism of hypersensitivity to proteins. However, these tests still need to be further verified for their effectiveness. 4.1.2 Skin sensitizers
4.1.2.1, Hazard categories
A substance is classified as a contact sensitizer according to the following principles: if there is human evidence that the substance causes allergies in many people through skin contact or if there is a protective effect from animal tests
4. 1.2.2 Special considerations
4.1.2.2.1 For classification of a substance, it must contain evidence of one or more of the following: - Positive data from patch tests: usually a clinically relevant dermatological finding; epidemiological studies showing that the substance causes allergic contact dermatitis: specific symptoms occur in most cases of contact under specific observation, even if the number of cases is small:
- Positive data from appropriate animal studies:
Closed-ended experimental data from human subjects:
Well-established allergic contact dermatitis data, usually from multiple infectious disease clinics. 4.1.2.2.2 Positive results from either human or animal studies are not sufficient for classification of a substance. Evidence from animal studies is usually much more reliable than evidence from human exposure; however, evidence may come from both sources, and sometimes there is a conflict between the two results, so the reliability of the evidence from both sources must be evaluated so that the classification problem can be resolved on a case-by-case basis. Normally, human data are not derived from controlled volunteer studies conducted at the date of hazard classification, but are only used as part of the risk evaluation to confirm that the effects of animal studies were insufficient. Therefore, human contact sensitization data are often obtained from controlled or other uncontrolled studies. Therefore, the evaluation of human data must be carefully based on the magnitude of the situation. In addition, the chemical properties of the substance and other factors such as exposure conditions, bioavailability, individual liability and preventive measures taken should also be considered. Human data should not normally be used to determine the results of animal studies.
4.1.2.2.3 If none of the conditions mentioned in 1.2 is met, the substance need not be classified as a contact sensitizer. However, the combination of two or more of the contact sensitization criteria listed below may change the classification decision. This requires consideration on a case-by-case basis. A case of contact dermatitis caused by excessive tenderness GE 20595-2006
Limited epidemiological studies. For example, when the standard has not been able to completely exclude accidental events, variability or confounding factors with reasonable confidence: - Data from animal experiments based on current guidelines that do not meet the criteria for the detailed conclusions described in 1.1.2.4.1 of this chapter,It is close enough to the effective limit; the number of positives obtained by non-standard methods is similar to the average result:
4.1.2.3 Immune contact urticaria Substances that meet the criteria for respiratory sensitization are called immune contact urticaria. These substances should also be considered as contact sensitizers. Substances that cause immune contact urticaria but do not meet the criteria for respiratory sensitization should also be considered as contact sensitizers. There is currently no recognized animal model for the evaluation of immune contact urticaria substances. Therefore, classification is usually based on the evidence of skin hypersensitivity reactions.
4.1.2.4 Animal studies
4.1.2.4.1 Skin allergy When using the wound test, at least 30% of the animals should show a reaction. For the non-adjuvant test method, if at least 15 animals react, it is considered positive. The skin allergy test method is defined as the repulsive tissue test (guinea pig maximum reaction test and 1Uchler sham test and Guideline 429 lymph node test). Other methods may be used provided they are well validated and widely tested: the mouse sensitizer test (MEST) has been shown to be a reliable screening test for the detection of moderate to strong sensitizers and can be used as a first step in the evaluation of skin sensitization potential, which can obviate the need for a further guinea pig test when the latter test is responsive.
4.1.2.4.2 In the evaluation of animal data from skin sensitization tests in accordance with the (FCD) domain equivalent guidelines, the ratio of irritated animals should be considered. This ratio is the sensitizing potential of the substance in relation to its moderate irritant dose: this dose may vary with the substance: if the substance is dose-sensitive, a more appropriate assessment of the sensitizing potential of the substance can be made. This is an area that requires further development. 4.1.2.4.3 There are substances that are extremely sensitizing at low doses. In contrast, other substances require high doses and prolonged exposure to determine sensitization. This may be better for the classification of hazard types: sensitizers and moderate sensitizers. 4.2 Classification of mixtures
4.2.1 Classification of mixtures when data are available for the mixture as a whole When there is reliable and good evidence from human experience or studies in appropriate experimental animals, the mixture can be classified based on a balance of evidence from these data. Care should be taken in assessing the data for the mixture to use a stated dose rather than to draw uncertain conclusions.
4.2.2 Classification of mixtures when data are not available for the mixture as a whole: bridging principles 4.2.2.1 When the mixture itself has no known sensitizing properties, but there is adequate data on the efficacy of the individual ingredients or similar test systems for the mixture, this data can be used by following an agreed bridging process. This ensures that the hazard classification of the mixture is based on the maximum possible use of the available data, and that additional or no testing of the mixture is required. 4.2.2. 2 Dilution
The allergenicity of a non-tenderizer is not expected to be affected by the dilution: the new mixture is classified as the same as the original mixture.
4.2.2.3 Production batches
The allergenicity of a production batch of a complex mixture can be assumed to be substantially equivalent to that of another production batch of the same commercial product or produced under the same control, unless there is reason to believe that the production of the batch has changed and there is no expected change in allergenicity. If this occurs, reclassification is required. 4.2.2.4 Substantially similar mixtures
Given the following conditions:
a) Two mixtures: 1) A+R,2+B:
CB20595—2006
h) The concentration of component 1 is substantially the same in both mixtures; c) The concentration of component A in mixture 1) is equal to that in mixture 2) 4.2.2.5 Aerosols Aerosol mixtures may be classified in the same hazard category as tested non-aerosol mixtures provided that the added propellant does not affect the sensitization properties of the mixture. 4.2.26 Classification of mixtures when data on all ingredients of the mixture are not available or when data on the efficacy of some ingredients are not available and at least one ingredient has been classified as a respiratory or skin sensitizer: The mixture may be classified as a respiratory or skin sensitizer when the liquid/gas meets or exceeds the narrow end point cut-off/concentration limits shown in Table 1 Table 1 Cut-off/concentration limits for ingredients of mixtures classified as skin sensitizers or respiratory sensitizers Classification of mixtures when data on all ingredients of the mixture are available or when data on the efficacy of some ingredients are available and at least one ingredient has been classified as a respiratory or skin sensitizer: The mixture may be classified as a respiratory or skin sensitizer when the liquid/gas meets or exceeds the narrow end point cut-off/concentration limits shown in Table 1 |tt||Skin sensitizer

Standard sensitizer
If a skin sensitizer is present as a component in a compound and its concentration is above 1.1%, then generally speaking, a safety data sheet (B/117519) is required as well as a label: Although the 1% limit value before H reflects the current formulation, in special cases, it may be necessary to select a lower limit of 1.5%. |tt||If a skin sensitizer is present as a component in a compound and its concentration is not less than 0.1% within two days, then a safety data sheet (GH/T 1.1) If a solid or liquid respiratory sensitizer is present as a component in the mixture and its concentration is between 0.1% and 1%, then generally both a safety data sheet (GB/T17319.1) and a warning label are required. Although the above critical values reflect the current system, in special cases, low-concentration information may also need to be transmitted. If a solid or liquid respiratory sensitizer is present as a component in the mixture and its concentration is not less than 0.1%, then a safety data sheet (GB/T17319.1) and a warning label are required. If a solid or liquid respiratory sensitizer is present as a component in the mixture and its concentration is between 0.1% and 0.2%, then both a safety data sheet (GB/T17319.1) and a warning label are required. 1) Although the threshold values are not in line with the current system, in special cases, it is also necessary to provide information below this level. If a gaseous respiratory sensitizer is present as a component in a mixture, and its concentration is not less than 0.2, the safety data sheet (GB/T17519.1) should be issued. 5 Decision process The following decision process is not part of the coordinated classification system, but is provided as additional guidance. It is recommended that the person responsible for classification should conduct research on the classification before and during the use of the decision process. 5.1 Decision process for respiratory sensitizers Substance: Does the substance have any respiratory data? Mixture: Does the mixture have any respiratory data? Can the classification rule be applied if it is not clear?
(see 4.2.2)
Does the mixture have any data/data on its use as a sleep sensitizer? (see 4.2.1) Is there evidence in humans that the mixture may cause specific respiratory sensitization, and,
are there positive results from an appropriate (general) animal test (see 4.1.1)
