In the fast-paced world of facilities management, ensuring the safety of both Personnel and infrastructure is paramount. One of the most critical aspects often overlooked is the danger of arc flash incidents. An arc flash is a sudden, explosive release of energy caused by an electrical fault. It can result in severe injuries, equipment damage, and even fatalities. For facilities managers, conducting an arc flash study is not just a regulatory compliance issue but a vital safety measure that can prevent catastrophic consequences.

Battery storage facilities are pivotal in the transition to renewable energy, but they come with inherent risks, particularly the threat of arc flash incidents. Arc flashes can cause severe injuries, costly damage, and operational downtime. Implementing robust arc flash risk management strategies is crucial for ensuring safety and reliability in these facilities. This blog will explore the significance of arc flash risk management and outline effective measures to mitigate these risks.

In today’s data-driven world, data centres are the backbone of every major industry, housing critical IT infrastructure that supports operations and services. While the focus often lies on cybersecurity and network uptime, another equally crucial aspect demands attention: arc flash risk management. Arc flashes are sudden, explosive releases of energy caused by an electrical fault, and they pose a significant danger to personnel and equipment in data centres. Here’s why effective arc flash risk management is essential and how it can be implemented.

We often get asked, why do arc flash studies matter when there are no prescriptive standards in place in the United Kingdom? Well, one good reason is, the majority of things that we would need to do when carrying out an arc flash study, are things we should have been doing for years before AF studies were even thought about.

Electrical Safety UK has been privileged to work extensively in most sectors, including the health services, and are experts in managing arc flash hazards.

The electrical risks within the rail industry are frequently underestimated, as is the broader network supporting the rail sector, we see around us. The danger is never far away, as many lines are electrified with overhead gantries carrying 25,000 volts a.c., and the innocent looking third rail at ground level that allows 750 volts d.c.

Electrical Safety UK have helped many companies in different industries in a number of locations around the World to improve their electrical safety management systems. In this article we are going to focus on Solar Farms and discuss whether there any hazards that may be specific to that industry.

The advent of the 18th Edition IET Wiring Regulations (BS 7671:2018) saw the introduction of Arc Fault Detection Devices, to which people quickly recognised that the requirement was a recommendation only which in many cases led to the requirement being largely ignored. As Amendment 2 of BS 7671 came into force this year, that original recommendation changed- in some instances, with it remaining a recommendation in many cases.

One question we are often asked is, what should an ESMS contain? This has prompted me to write a series of articles looking at the different aspects of these vital documents. Here is the third article in that series.

We specialise in providing electrical PPE, safety knowledge, equipment, and training for hazards such as arc flash. An important aspect of protecting electrical professionals is Personal Protective Equipment (PPE). PPE is equipment that will protect the user against health or safety hazards.

Is Arc Flash a UK Legislative Requirement? Electrical Safety UK specialises in carrying our arc flash studies for our many clients. One of the things that come up regularly is the question of legislation and whether or not arc flash risk management is required under UK law. The short answer is yes.

The Second Edition of IEEE 1584 – IEEE Guide for Arc Flash Hazard Calculations Studies was 16 years in the making. In this 1-hour video, Vice-Chair of IEEE 1584, Jim Phillips takes you through the long history of what it took to develop the next edition including establishing a collaboration between IEEE and NFPA, creating a project team for the almost 2000 new arc flash tests, model and equation development and more.

The simple answer is yes. By virtue of Regulation 4(1) of the Electricity at Work Regulations 1989 and Regulation 3(1) of the Management of Health and Safety at Work Regulations 1999, the need to carry out a suitable and sufficient risk assessment of risk and to put measures in place to protect those who could be put at risk is mandated.

In order that we can accurately carry out an Arc Flash Study on a client’s electrical installation we require the calculated prospective fault level at the point of connection with the Distribution Network Operator (DNO).

Principal Electrical Engineer, Paul Hopton, explores the process of identifying Arc Flash risk, how Incident Energy is calculated, and what is entailed within the Arc Flash Study itself, and so much more.

Principal Electrical Engineer, Paul Hopton, explains Arc Flash personal protective equipment ratings.

The best and most often used control measure to protect personnel from arc flash is to isolate the equipment before you work on it.

 Andy Linley, Compliance Director at Electrical Safety UK Ltd, discusses Arc Flash training; the legislative requirements behind it and what good training should encompass.

Arc Flash risk associated with alternating current systems has been well studied and is becoming better understood. People have become familiar with the increased incident energy levels generally associated with Low Voltage, and less frequently associate Arc Flash as a high voltage problem.

Deputy MD, Paul Hopton, outlines the additional considerations in a wind turbine environment and highlights the potential consequences of arc flash incidents.

Compliance Director, Andy Linley, discusses Arc Flash Boundary distances, what they are and factors affecting them.

Paul Hopton, Deputy Managing Director and Principal Electrical Consultant, discusses when Arc Flash Protection is required, carrying out Risk Assessments to determine the requirement and suitable competency of those involved.

In an ever-growing world of sustainable environmental vehicle solutions, Principal Electrical Consultant Paul Hopton discusses the risk of Arc Flash when working with batteries installed in Electric Vehicles. Concerns of Competency for mechanics required to work on these systems, the types of activities that could cause an electrical incident, and what can be done to mitigate risk.

After 13 years of Employment with Electrical Safety UK Limited it is Mike’s decision to retire from the company. Mike Frain founded Electrical Safety UK in September 2004. Mike has contributed many years of experience and knowledge to the Electrical Industry.

Our analysis using arc flash voltage charts show the biggest risk may occur at a low voltage instead of high voltage. The incident energy level defines the severity of the arc flash hazard when using the IEEE 1584 standard.
