Book Description
John Ridley and Dick Pearce, both recognized specialists in machinery safety, guide the reader through the various standards, regulations and best practices relating to the safe design and use of machinery and show which standard is relevant for which type of machine. Safety with Machinery provides a basic grounding in machinery safety and covers safeguarding philosophy and strategy, typical hazards, risk assessment and reduction, guarding techniques, ergonomic considerations, safe use of equipment and plant layout. All types of safeguards are discussed – mechanical, interlocking, electrical / electronic / programmable, hydraulic, pneumatic. The new edition has been updated throughout in line with changes in regulations and standards. The section on electric, electronic and programmable safety systems has been expanded to reflect their increasing importance. The book now focuses on the harmonised standards (e.g. EN ISO 13849, IEC/EN 61131-2) which can be used by manufacturers to self-certify their machines for the European market without the need for third party examination, but also covers other relevant standards (e.g. IEC 62061). Many practical examples set the regulations in context and assist in the interpretation of the various standards. Safety with Machinery is essential reading for all engineers involved in machinery design and maintenance all over the world as every machine sold within or into the EU needs to conform to the harmonised standards. It also provides health and safety professionals, students and employee representatives, as well as certification bodies, health and safety inspectors and safety regulators with a comprehensive overview of machinery safety.

Risk Assessments and Safe Machinery
Author: Torben Jespen
Publisher: Springer
ISBN: 3319313614
Category : Technology & Engineering
Languages : en
Pages : 263
Book Description
This book describes the prerequisites for the placing on the market and the safe use of machinery in compliance with the relevant EU Directives, especially the Machinery Directive 2006/42. It provides readers with high-level knowledge concerning the Essential Health and Safety Requirements (EHSR) that machinery must fulfill. The approach and principles of the Machinery Directive were most recently made worldwide acknowledged in the ILO code of practice on safe machinery, released in 2013. The book addresses that code, as well as providing valuable insight into other EU Product and Workplace legislation. Focusing on the key aspect of safe machinery, the “machinery safety risk assessment”, which allows readers to better understand the more difficult aspects of risk assessments, the book equips readers to tackle problems at the manufacturing stage and in different use scenarios, introducing them to risk reduction techniques and functional safety aspects.

Safe Design and Construction of Machinery
Author: Elizabeth Bluff
Publisher: CRC Press
ISBN: 1317060091
Category : Political Science
Languages : en
Pages : 367
Book Description
The origin of this book is the compelling evidence that a high proportion of machinery-related deaths and injuries are attributable to genuine and serious risks originating within machine design and construction. This trend continues despite significant legal obligations, notably the European regulatory regime giving effect to the Machinery Directive (among others), and a substantial body of specialist knowledge originating in the disciplines of human factors and safety engineering. Grounded in empirical research with machinery manufacturers, this book aims to elucidate the factors and processes shaping firms’ performance for machinery safety, and considers their compatibility with legal obligations. Through a unique blending of rich empirical data coupled with safety, human factors, socio-legal and learning scholarship, the book provides both a nuanced account of firms’ performance for machinery safety, and makes conceptual and theoretical contributions to understanding and explaining their performance. Specifically, the book elucidates the role of knowledge and motivational factors - and how these are constituted - in shaping firms’ performance. It reveals the multiple state and non-state influences that create plural responses among manufacturing firms, which typically operate in supply chains and networks, and often globally. These insights provide the foundations to enhance regulatory design, and the book’s conclusion recommends some innovative directions for regulatory interventions to sustain the safe design and construction of machinery.

Functional safety of machine controls
Author: Hauke, M.
Publisher: DGUV/IFA
ISBN: 3864232325
Category : Technology & Engineering
Languages : en
Pages : 324
Book Description
The EN ISO 13849-1 standard, “Safety of machinery – Safety-related parts of control systems”, contains provisions governing the design of such parts. This report is an update of BGIA Report 2/2008e of the same name. It describes the essential subject-matter of the standard in its third, revised 2015 edition, and explains its application with reference to numerous examples from the fields of electromechanics, fluidics, electronics and programmable electronics, including control systems employing mixed technologies. The standard is placed in its context of the essential safety requirements of the Machinery Directive, and possible methods for risk assessment are presented. Based upon this information, the report can be used to select the required Performance Level PLr for safety functions in control systems. The Performance Level PL which is actually attained is explained in detail. The requirements for attainment of the relevant Performance Level and its associated Categories, component reliability, levels of diagnostic coverage, software safety and measures for the prevention of systematic and common-cause failures are all discussed comprehensively. Background information is also provided on implementation of the requirements in real-case control systems. Numerous example circuits show, down to component level, how Performance Levels a to e can be engineered in the selected technologies with Categories B to 4. The examples provide information on the safety principles employed and on components with well-tried safety functionality. Numerous literature references permit closer study of the examples provided. The report shows how the requirements of EN ISO 13849-1 can be implemented in engineering practice, and thus makes a contribution to consistent application and interpretation of the standard at national and international level.
