Beschreibung

This book is an essential guide and support to understanding of the science and policy, procedure and practice that underpins the REACH risk assessments required for the use and placing on the market of chemicals in the European Union. A clear understanding of information provision and how this affects the assessment of chemical safety is fundamentally important to the success of policy on chemicals and ultimately to the sustainability of the chemicals industry. Within the book, the scientific processes that underpin the policy are explained in a practical way. Importantly, it includes coverage of techniques to help solve the problems of using potentially risky and hazardous chemicals through the use of less hazardous alternatives and 'green chemistry', and also the analysis of the risks of the use of the most hazardous substances against the social and economic benefits of use. Chemical Risk Assessment: A Manual for REACH covers the following main themes: i) Assessment of chemical risk; ii) Risk management; iii) Hazard reduction, substitution and green chemistry; iv) Risk versus benefit - socio-economic analysis. The book acts as a practical guide and overview to chemicals risk assessment and risk management (in the EU context), as well as a support text for planning for the challenges of the future, which will see ever-increasing pressure to withdraw hazardous substances from the EU (and global) market, balanced against opportunities for innovation in the development of less hazardous chemicals.

Preface

How to Use This Book

This book about REACH is a handbook, providing practical advice aimed at the level of consideration of strategy, technical insights, and commercial realities. It does not intend to reproduce or summarise the official detailed guidance – of which there are many thousands of pages! Although that level of detail and amount of guidance is necessary, the abundance of guidance can in itself create problems. It is not possible for a single individual to absorb and understand such a huge amount of information, especially considering the diversity of issues concerning chemical properties, hazards, and risks. This book can help you understand REACH, whatever your responsibilities or interest in it.

What this handbook does do is provide a broad overview, but one that includes the details that the authors have found necessary in their experience in practice of all aspects of the REACH Regulation. The purpose of the book is to explain how REACH works, with an emphasis on an overall understanding and explanation of responsibilities, in order to help you to set strategy and priorities.

What is REACH Trying to Achieve?

REACH has many objectives, contained within what is one of the most comprehensive pieces of legislation ever enacted in the European Union. Its major objectives include:

bringing all REACH-relevant substances, regardless of whether they have been previously assessed or not, into a common registration and evaluation process;

moving the burden of responsibility more clearly into the hands of industry;

placing priority of effort onto substances of very high concern;

improving communication in the supply chain;

encouraging the sharing of data between data owners;

widening the availability of data on substances;

removing unacceptably hazardous substances from the market.

How Can This Book Help You Understand REACH and Comply With It?

This book will help you to understand your part in REACH:

Policy maker

– business strategy in the chemicals industry in the European Union requires an awareness of the costs and impacts of REACH. This involves understanding the current and potential status of substances under REACH, and also how other related legislation may be affected.

Business manager

– if you are developing a substance or group of substances you will have to understand REACH, to ensure that appropriate and timely actions on substance are taken.

Scientist in R&D

– it is not possible to maintain the view that R&D can be seen as separate from acceptability in commercial and regulatory terms – you need to be informed about REACH and its impacts on substances with potentially hazardous properties.

Regulator

– if you are not working on REACH, then this book can help you understand how your work interfaces with REACH.

Specialist or Consultant

– you need to know where your speciality fits into the bigger picture of REACH.

Chapter 1

Introduction: Policy and Scientific Context of Chemicals Risk and Risk Management

This chapter acts as a foundation of understanding for the rest of the book. It introduces the regulatory systems that demand the evaluation of risk for chemical substances that are intended to be used and placed on the market. It sets out the development of risk assessment in the European, global and national contexts. This chapter also explains the key concepts of hazard and exposure. Hazard is defined as the inherent properties of a substance that may make it harmful – flammability, toxicity and so on. Exposure refers to the ways in which humans and the environment come into contact with substances. The reasons for bringing together hazard and exposure in order to understand risk are explained.

The focus of this book is the REACH Regulation (most often referred to just as ‘REACH’), as this is the main regulatory driver for the risk assessment of chemical substances in the European Union. REACH (Registration, Evaluation, Authorisation & restriction of Chemicals), however, should be viewed in the context of other legislation that is either directly or indirectly connected to the REACH Regulation. With this in mind, the later sections of this chapter include consideration of United Kingdom legislation on chemicals, including worker and environmental protection. These sections are intended to serve as examples of how REACH is connected to prior legislation and how compliance with REACH works with such legislative regimes at national level.

The purpose of this book is to set out in a simple and concise way how to assess and manage the risks of chemicals to humans and the environment. This is done within the context of the main legislation that applies to the safety of the manufacture and use of chemicals in the European Union (EU) – the REACH Regulation. It is not the intention to give detailed guidance on each aspect of risk assessment or in depth assessment of specific aspects of REACH, but rather to explain the main aspects of chemical risk assessment and the processes that are applied, so that each aspect can be understood within the context of REACH. This book should act as a handbook, so the reader/user can find out about specific aspects of the process and technical elements in sufficient detail to understand where and how they fit in the risk assessment of chemicals, and where to look for more detailed information.

Legislation on chemicals has specific purposes and is aimed at control of particular processes or aspects of the manufacture, use, reuse and disposal of chemicals. In addition, some legislation is aimed at chemicals that are used in a particular way (for example pharmaceuticals or pesticides), or because they have specific dangerous qualities (carcinogens, explosives and highly flammable substances), and some legislation is aimed at protection of specific sections of the population (e.g. workers, consumers, pregnant workers). Other legislation is aimed at environmental protection by specific control of releases to the environment (e.g. integrated pollution potential and control – IPPC) or monitoring specific parts of the environment (e.g. the Water Framework Directive – WFD for water). Inevitably there is overlap between all this legislation on chemicals, and today companies manufacturing and using chemicals have to be aware of a wide range of legislation to ensure that they are complying with all the relevant laws to operate legally and safely.
