PROPOSAL FOR REVISION OF CHAPTER 2.8 OF THE MODEL REGULATIONS (NETHERLANDS)
Replace current Chapter 2.8 in the Model Regulations with the following text: “CHAPTER 2.8 CLASS 8 – CORROSIVE SUBSTANCES 2.8.1 Definitions and general provisions 2.8.1.1 Class 8 (corrosive) substances are substances which, by chemical action, lead to the production of irreversible damage to the skin; namely, visible necrosis through the epidermis and into the dermis, following the application of a test substance for up to 4 hours and observation periods of up to 14 days, or, in the case of leakage, will materially damage, or even destroy, other goods or the means of transport. 2.8.1.2 For substances and mixtures that are corrosive to skin, hazard classification is determined using criteria in section 2.8.2. (...) In a total weight of evidence approach all available information bearing on the determination of skin corrosion is considered together, including the results of appropriate validated in vitro tests, relevant animal data, and human data such as epidemiological and clinical studies and well-documented case reports and observations. 2.8.2.1 Hazard classification corrosive to skin based on standard animal test data 2.8.2.1.1 A substance is corrosive to skin when it produces destruction of skin tissue, namely, visible necrosis through the epidermis and into the dermis, in at least one tested animal after exposure for up to 4 hours. (...) ST/SG/AC.10/C.3/2014/69 ST/SG/AC.10/C.4/2014/12 5 Table 2.8.1: Skin corrosion hazard classificationa Criteria Class 8 Destruction of skin tissue, namely, visible necrosis through the epidermis and into the dermis, in at least one tested animal after exposure ≤ 4 h Class 8A Corrosive responses in at least one animal following exposure ≤ 3 min during an observation period ≤ 1 h Class 8B Corrosive responses in at least one animal following exposure 3 min and ≤ 1 h and observations ≤ 14 days Class 8C Corrosive responses in at least one animal after exposures 1 h and ≤ 4 h and observations ≤ 14 days a The use of human data is addressed in GHS 3.2.2.2 and in GHS chapters 1.1 (par. 1.1.2.5 (c)) and 1.3 (par.. 1.3.2.4.7). 2.8.2.2 Hazard classification in a tiered approach 2.8.2.2.1 A tiered approach to the evaluation of initial information shall be considered, where applicable (Figure 2.8.1), recognizing that not all elements may be relevant. 2.8.2.2.2 Existing human and animal data including information from single or repeated exposure shall be the first line of evaluation, as they give information directly relevant to effects on the skin. 2.8.2.2.3 Acute dermal toxicity data may be used for classification.
