    Report of the Workshop on a Framework for the Development and Use Of Integrated Approaches to Testing and Assessment

    This document is a report of the Workshop on a framework for the development and use of integrated approaches to testing and assessment which was held on 17-19 November 2014 in Crystal City VA, USA. This framework should provide guiding principles, and technical guidance on how results from alternative approaches (in silico, in chemico, in vitro including high throughput and high content test methods) should be interpreted for characterising (both qualitatively and quantitatively) the adverse effects in animals and humans and/ or the environment, so that they can be used for hazard identification, hazard characterisation and risk assessment. The workshop was organised in close cooperation with the World Health Organisation following a proposal from OECD member countries in June 2013.

    OECD Guidance for Characterising Hydrocarbon Solvents for Assessment Purposes

    This document presents a harmonized method for characterising, for assessment purposes, a specific subcategory of UVCBs (Substances of Unknown or Variable composition, Complex reaction products or Biological materials): hydrocarbon solvent substances. The method presented in this document gives guidance on how hydrocarbon solvent substances can be characterised in a way that their composition is accurately and consistently reflected. This ensures that substances with the same chemical composition, manufactured in different countries, can be characterised with the same description for hazard assessment purposes. A common understanding and approach to characterising UVCBs would enable regulatory authorities to increase cooperation in the field of hazard assessment and help industry deal with regulatory requirements from multiple jurisdictions.

    Corporate governance for process safety - Guidance for senior leaders in high hazard industries

    The Guidance on Corporate Governance for Process Safety draws attention to those at the top of industry to the need for high standards of corporate governance in relation to the management of high hazard industries. The Guidance encourages every director, CEO and President of a major hazard company and to check themselves against a set of self-assessment questions and evaluate their awareness and knowledge in process safety.

    Guidance Document on an Integrated Approach on Testing and Assessment (IATA) for Skin Corrosion and Irritation

    This Guidance Document proposes an integrated approach on testing and assessment (IATA) for skin corrosion and irritation. It also provides consistent information on key characteristics of each of the individual information sources of the IATA, and relevant guidance on how to integrate information for decision making (including decisions on the need for further testing) for final decisions for classification and labelling.

    Guidance Document for Describing Non-Guideline In Vitro Test Methods

    The purpose of this guidance is to harmonise the way non-guideline in vitro methods are described and thereby facilitate an assessment of the relevance of test methods for biological activities and responses of interest, and an assessment of the quality of data produced, irrespective of whether these tests are based on manual protocols or assay protocols adapted for use on automated platforms or high-throughput screening systems (HTS). This guidance outlines the elements considered relevant for providing a comprehensive description of an in vitro method to facilitate the interpretation of results and support scientifically defensible fit-for-purpose applications.

    OECD Guidance for Characterising Oleochemical Substances for Assessment Purposes

    This document presents a harmonized method for characterising, for assessment purposes, a specific subcategory of UVCBs (Substances of Unknown or Variable composition, Complex reaction products or Biological materials): oleochemical substances. Many oleochemicals are UVCBs, due to the variability in the composition of the starting materials. The method presented in this document gives guidance on how oleochemical substances can be characterised in a way that their composition is accurately and consistently reflected to ensure that substances with the same chemical composition, manufactured in different countries, can be characterised with the same description for hazard assessment purposes. A common understanding and approach to characterising UVCBs would enable regulatory authorities to increase cooperation in the field of hazard assessment and help industry deal with regulatory requirements from multiple jurisdictions.

    Report on Considerations from Case Studies on Integrated Approaches for Testing and Assessment (IATA) - First Review Cycle (2015) - Case Studies on Grouping Methods as a Part of IATA

    OECD member countries have been making efforts to expand the use of alternative methods in assessing chemicals. The OECD has been developing guidance documents and tools for the use of alternative methods such as (Q)SAR, chemical categories and Adverse Outcome Pathways (AOPs) as a part of Integrated Approaches for Testing and Assessment (IATA). There is a need for the investigation of the practical applicability of these methods/tools for different aspects of regulatory decision-making, and to build upon case studies and assessment experience across jurisdictions. The objective of the IATA Case Studies Project is to increase experience with the use of IATA by developing case studies, which constitute examples of predictions that are fit for regulatory use. The aim is to create common understanding of using novel methodologies and the generation of considerations/guidance stemming from these case studies. This document reports the learnings and lessons obtained from the review experience of the four case studies submitted to the 2015 review cycle of the IATA Case Studies project. The topics discussed in this document include the strongest aspects and uncertainties of each case study, and the document identifies areas for developing further guidance on IATA.

    New Scoping Document on in vitro and ex vivo Assays for the Identification of Modulators of Thyroid Hormone Signalling

    This scoping document aims at bringing forward relevant in vitro and ex vivo thyroid assays to the attention of OECD member countries, to provide recommendations for their development/use, and also, to identify aspects/blocks of the thyroid signalling pathways that are not covered and would require further development of thyroid assays.

    Guidance Document on Considerations for Waiving or Bridging of Mammalian Acute Toxicity Tests

    Acute toxicity tests are an area of focus for developing alternative assays and approaches to address animal welfare concerns. In the context of this document, acute toxicity studies refer to studies involving a single exposure to a test chemical and include those assessing systemic toxicity as well as those assessing local irritation, corrosion or sensitization. One approach to minimizing the use of animals for acute toxicity testing is to consider waiving a study that may be required based on scientific criteria. Another approach to reducing or eliminating animal testing is to use existing hazard information that is informative for the acute toxicity endpoint for the test chemical; this would include the use of hazard information for one or multiple similar test chemicals to characterize the hazard for another or for mixtures, the use of recognized calculation approaches and bridging concepts. This Document provides clarification on these approaches to ensure that regulatory authorities are provided with the appropriate data required for decision-making and that reduced animal testing can be undertaken without compromising the integrity of the hazard information.

    Testing Programme of Manufactured Nanomaterials

    The safety of Manufactured Nanomaterials is an important concern impacting regulatory bodies throughout the world. Due to their size, Manufactured Nanomaterials may require additional testing beyond the standard suite of tests used for other chemicals, to ensure that the impact on human health and the environment is fully understood - download Manufactured Nanomaterials Dossiers or search for Tested Endpoints.
