Electrical Safety In Arc Welding

Provides guidance on the installation, use and maintenance of hand-held arc welding equipment. Aimed at those who manage or supervise work where this type of equipment is used and those who specify or buy in such equipment. Special or unusual operations such as welding under water are excluded. It amends advice relating to earthing, where welding sets with reinforced transformer insulation are brought into use. Contents: Processes and equipment; The welding circuit; Electrical hazards; Precautions; Fire precautions; Information and training; Inspection and maintenance.

This book explains the various environmental and health hazards due to electricity in its many forms, and sets out methods and practices to reduce risks.

"This Technical Note was developed in response to a recent series of electrical safety incidents in the welding and fabrication industries. It is designed to provide practical guidance and a summary of the latest information available from a wide range of research and experience, with the goal of helping to prevent such incidents. The Technical Note addresses issues such as the hazards of particular equipment and processes, the effect of electric current on the human body and safe working practices including risk assessment and avoidance. It utilises case studies to emphasise common problem areas and includes a guidance note on Voltage Reduction Devices for MMAW and arc gouging power sources." - product description.

Electrical Safety and the Law describes the hazards and risks from the use of electricity, explaining with the help of case studies and accident statistics the types of accidents that occur and how they can be prevented by the use of safe installations, equipment and working practices. It describes the British legislation on the safety of electrical systems and electrotechnical machinery control systems, much of which stems from European Directives and which will therefore be affected by the UK’s decision to leave the EU (Brexit), and the main standards and guidance that can be used to secure compliance with the law. There are detailed descriptions covering the risks and preventive measures associated with electrical installations, construction sites, work near underground cables and overhead power lines, electrical equipment and installations in explosive atmospheres, electrical testing and electrotechnical control systems. Duty holders’ responsibilities for designing, installing, and maintaining safe systems are explained, as well as their responsibilities for employing competent staff. The fifth edition has been substantially updated to take account of considerable changes to the law, standards and guidance; it has been expanded to include: a new chapter on the Corporate Manslaughter and Corporate Homicide Act; a new chapter describing landlords’ legal responsibilities for electrical safety in private rented properties and social housing; a new chapter on the Electricity Safety Quality and Continuity Regulations; new information on offences, penalties, sentencing guidelines, and relevant case law; a description of the main requirements of BS 7671:2008 and other principal standards, many of which have been amended in recent years; new cases studies to illustrate the hazards and risks; information on changes to GB’s health and safety system.
