The European Arc Flash Guide


Book Description

This book is essential reading for anyone responsible for designing or putting workers to task on, or near, large power electrical systems. This is especially relevant where local health and safety law uses a risk-based approach to electrical safety such as in Europe. It is based upon a bedrock of risk management methodology using the 4Ps of Predict, Prevent, Process and Protect to ensure that arc flash hazards are systematically identified, analysed, and prevented from causing harm. Each of the 4Ps are described in detail starting with a quantitative prediction of harm from the arc flash hazard and then a separate chapter on prevention based upon practical measures avoid or minimise harm set against a hierarchy of risk control measures. The chapter on process, policy and procedures gives advice on a methodical approach to creating rules and ensuring competence. Finally, the chapter on protection describes, as a last resort, how personal protective equipment can be selected, used, and maintained. This book is packed with the fruits of the author’s vast experience and there is a chapter dedicated to myths and mysteries as well as separate chapters for electrical utilities, duty holders, service providers, contractors, legislation, and data collection.

Emergency Response Guidebook


Book Description

Does the identification number 60 indicate a toxic substance or a flammable solid, in the molten state at an elevated temperature? Does the identification number 1035 indicate ethane or butane? What is the difference between natural gas transmission pipelines and natural gas distribution pipelines? If you came upon an overturned truck on the highway that was leaking, would you be able to identify if it was hazardous and know what steps to take? Questions like these and more are answered in the Emergency Response Guidebook. Learn how to identify symbols for and vehicles carrying toxic, flammable, explosive, radioactive, or otherwise harmful substances and how to respond once an incident involving those substances has been identified. Always be prepared in situations that are unfamiliar and dangerous and know how to rectify them. Keeping this guide around at all times will ensure that, if you were to come upon a transportation situation involving hazardous substances or dangerous goods, you will be able to help keep others and yourself out of danger. With color-coded pages for quick and easy reference, this is the official manual used by first responders in the United States and Canada for transportation incidents involving dangerous goods or hazardous materials.




Occupational Injuries From Electrical Shock and Arc Flash Events


Book Description

This brief presents information on occupational injuries from electric shock and arc flash events through a review of literature, electrical incident data, and similar sources. It includes pertinent information such as the nature of the incident, adherence to safety requirements, use of appropriate personal protective equipment (PPE), and extent of injury. Chapters address arc flash and shock hazards, and the need for empirical incident data on the actual hazards that may be experienced when equipment faults or adverse electrical events occur. Certain tasks where the risk of an arc flash or shock hazard may be lower, such as normal operation of properly installed and maintained equipment, may not require the use of any special PPE. Some of this risk reduction is based on anecdotal data, and the brief details why future research challenges will need more empirical incident data on the actual hazards and associated injuries that may be experienced when equipment faults or adverse electrical events occur. Designed for professionals and researchers in fire protection engineering, workplace electrical tasks, or workplace safety, this brief offers a thorough overview of the trends in electrical injuries and the costs related to those injuries.
