This is the second edition of the World Health Organization (WHO) handbook on the safe sustainable and affordable management of health-care waste - commonly known as the Blue Book. The original Blue Book was a comprehensive publication used widely in health-care centres and government agencies to assist in the adoption of national guidance. It also provided support to committed medical directors and managers to make improvements and presented practical information on waste-management techniques for medical staff and waste workers. In many countries knowledge about the potential for harm from health-care wastes has now become more prominent to governments medical practitioners and civil society. Increasingly managers and medical staff are expected to take more responsibility for the wastes they produce from their medical care and related activities. The indiscriminate and erratic handling and disposal of waste within health-care facilities is now widely recognized as a source of avoidable infection and is synonymous with public perception of poor standards of health care. It has been more than ten years since the first edition of the Blue Book. During the intervening period the requirements on generators of health-care wastes have evolved and new methods have become available. Consequently WHO recognized that it was an appropriate time to update the original text. The purpose of the second edition is to expand and update the practical information in the original Blue Book. The new Blue Book is designed to continue to be a source of impartial health-care information and guidance on safe waste-management practices. The editors'intention has been to keep the best of the original publication and supplement it with the latest relevant information. The audience for the Blue Book has expanded. Initially the publication was intended for those directly involved in the creation and handling of health-care wastes: medical staff health-care facility directors ancillary health workers infection-control officers and waste workers. This is no longer the situation. A wider range of people and organizations now have an active interest in the safe management of health-care wastes: regulators policy-makers development organizations voluntary groups environmental bodies environmental health practitioners advisers researchers and students. They should also find the new Blue Book of benefit to their activities. Chapters 2 and 3 explain the various types of waste produced from health-care facilities their typical characteristics and the hazards these wastes pose to patients staff and the general environment. Chapters 4 and 5 introduce the guiding regulatory principles for developing local or national approaches to tackling health-care waste management and transposing these into practical plans for regions and individual health-care facilities. Specific methods and technologies are described for waste minimisation segregation and treatment of health-care wastes in Chapters 6 7 and 8. These chapters introduce the basic features of each technology and the operational and environmental characteristics required to be achieved followed by information on the potential advantages and disadvantages of each system. To reflect concerns about the difficulties of handling health-care wastewaters Chapter 9 is an expanded chapter with new guidance on the various sources of wastewater and wastewater treatment options for places not connected to central sewerage systems. Further chapters address issues on economics (Chapter 10) occupational safety (Chapter 11) hygiene and infection control (Chapter 12) and staff training and public awareness (Chapter 13). A wider range of information has been incorporated into this edition of the Blue Book with the addition of two ne

Adequate provision of water supply, sanitation, hygiene and waste management in schools has a number of positive effects and contributes to a reduced burden of disease among children, staff and their families. Such interventions also provide opportunities for greater gender equity in access to education, and create educational opportunities to promote safe environments at home and in communities. This document provides guidance on water, sanitation and hygiene required in schools. The guidelines it contains are designed to be used in low-cost settings in low- and medium resource countries, and to support the development and implementation of national policies.--Publisher's description.
