News & views from ESUK

This year marks a significant milestone for our Electrical Safety UK Limited as we celebrate 20 years of dedicated service and unwavering commitment to providing a Holistic Approach to Electrical Safety. From humble beginnings to becoming a trusted name in the industry, our journey has been driven by a passion for safety, innovation, and continuous improvement.

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.

Lithium-ion batteries (Li-ion) are revolutionising the automotive industry by powering electric vehicles (EVs), offering high energy density, lightweight design, and sustainable mobility solutions. However, alongside their benefits, understanding and mitigating the fire risks associated with these batteries is crucial for ensuring the safety of EVs and their passengers. These vehicles, under certain conditions, can pose fire risks due to a phenomenon known as thermal runaway.

The world is undergoing a significant shift towards renewable energy sources, and battery storage systems are playing a pivotal role in this transition. In the UK, these systems are crucial for achieving a cleaner and more sustainable energy future.

As we bid farewell to a year of resilience and adaptation, the Team at ESUK is brimming with excitement for what lies ahead. This past year, despite unforeseen challenges navigating the exit of Covid restrictions, we achieved remarkable milestones, surpassing our Q1 goals and securing partnerships with leading players in the renewables industry.

The purpose of an Authorisation of Electrical Personnel Procedure is to describe the general procedures and methods that should be adopted to ensure that all Electrical personnel who carry out work on Electrical Distribution Systems or equipment connected to them are, and continue to be, competent to carry out the duties of their role.

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.

The purpose of a Management of Ageing and Obsolete Electrical Equipment Procedure is to set out how the ageing and obsolescence of electrical equipment should be managed within your business or site. The procedure should provide a proactive system for managing specific ageing and obsolete electrical assets.

Earthing is defined in BS 7671 as the connection of exposed conductive parts of an installation to the main earthing terminal of that installation. Whilst this may be a useful definition, it does not fully encompass the full meaning of earthing, bonding and automatic disconnection of supply.

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

Electrical Safety UK services to the water industry have included writing electrical safety rules and supporting procedures for household name companies and training 1000s of direct staff and contractors, including designing and delivering competence assessments.

On Tuesday, 25th April 2023, we hosted a successful conference on Arc Flash, understanding global standards. The conference featured eminent industry experts who shared their knowledge and insights on the topic, including Jim Phillips, Mike Frain, and Paul Hopton. The attendees were from a diverse range of sectors, indicating the widespread interest in the topic.

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.  

Electricity is a hazard, as it is dangerous and may cause harm. If properly managed, the likelihood of electrical hazards is minimal, but the severity when things go wrong can be fatality or life-changing.

Arc flash PPE has become the default control measure and within the United States, until recently, was the prescribed control measure. However, within the UK and within Europe, this is not the case and legally (through Regulation 4 and Schedule 1 of the Management of Health and Safety at Work Re …

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.

This is often a question we get asked, and in many cases, our reply is, ‘why do people need to go into an electrical control panel’? Demands on maintenance and service engineers often means that there is a lack of available competent persons who can react quickly when things stop working.

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

The answer is both yes and no. Regulation 4(1) of the Electricity at Work Regulations 1989 states, ‘all systems shall at all times be of such construction to prevent, so far as is reasonably practicable, danger’. In this instance, the term construction refers to an electrical system’s design, construction, and operation, including equipment that forms part of that system.

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.

In the past nearly all large industrial sites would have at least one chartered or degree qualified electrical engineer on the staff.

What is an electrical control panel? An electrical control panel is an enclosure, typically a metal box or plastic moulding which contains important electrical components that control and monitor a number of mechanical processes.

As most of Britain enjoys an unseasonably warm summer, many of us are forced to suffer the torture of heat whilst at work.

How much change is there between the 17th Edition and the latest updates of BS 7671 to the 18th Edition? How much will it affect you and your business?

People often underestimate the risks that simple factors play in electrical safety, from missing bolts in panel doors, un-blanked openings, corroded enclosures and ingress of liquids or dust. We explore some of the most common hazards below:

The 18th Edition has been with us now for 9 months and since January has been the defacto standard to which all electrical installation work should comply. For those who have remained abreast of amendments 1, 2 and 3 of the 17th Edition, the 18th Edition and its changes should pose little concern.

The Greek Philosopher Heraclitus is credited with the phrase “The only thing that is constant is change.” That is certainly the case with the new 2018 Edition of IEEE 1584 ‘IEEE Guide for Performing Arc-Flash Hazard Calculations’. Almost everything has changed – except the title! The first edition of IEEE 1584 was published on September 23, 2002

This week I worked with a site engineer in isolating a supply to a section board. All went well with identifying the place of work and the point of isolation, along with obtaining permission to isolate.

Globally, Coronavirus (COVID-19) is affecting the lives of many businesses and individuals. Employers are implementing policies and procedures never seen before to help ensure businesses survive. These are trying times, but the usual bulldog British spirit is already shining through.

Coming into force on the 1st April 1990 Regulation 3 of the Electricity at Work Regulations 1989 introduced the term ‘Duty Holder’, or more specifically ‘persons on whom duties are imposed’. The introduction to HSE publication HSR 25: Electricity at Work Regulations 1989; Guidance on the Regulations clarifies in paragraph 5 that ‘[t]he guidance is primarily for duty holders (including those involved in the design, construction, operation or maintenance of electrical systems and equipment), engineers, technicians and their managers’.

The statistics are out for period 2017-2018 relating to fatalities reported to the Health and Safety Executive. The good news is that only two fatalities occurred as a result of coming into contact with electrical energy, one was an employee and the other was self-employed. This represents 1.4% of the total reportable workplace fatalities.

You cannot smell, hear, or see electricity, so making sure you have the right systems in place to manage this hazardous energy is critical to the wellbeing of your employees and your Company. 

A question that is often asked is how often should my electrical equipment be tested at work? Often referred to as PAT Testing (which in itself is incorrect as it becomes Portable Appliance Testing- Testing) the In-Service Inspection and Testing of Electrical Equipment is required by regulation 4(2) of the Electricity at Work Regulations 1989. The regulation requires equipment that may become dangerous if neglected to be maintained to prevent such danger from arising. HSR 25, Guidance on the Regulations identifies inspection and testing as being a means of verifying that maintenance is effective, but recognises that other methods of compliance do exist.

DSEAR stands for Dangerous Substances and Explosive Atmospheres Regulations. It is important to learn about DSEAR in the workplace to identify serious hazards and know how to assess the risk involved.

Switching off the supply of electricity to allow for safe working is legally mandated, with work on or near to live electrical systems permitted in exceptional circumstances only. Electrical isolation consists of two clear stages: switching off the supply and proving dead. It is important you follow a safe isolation procedure.

BS 7671:2018+A1:2020 is a non-statutory document based on technical substance of European CENELEC agreements, and is published by the British Standards Institute under the joint direction of the Institution of Engineering and Technology (IET) and British Electrotechnical Committee (BEC).

Inspection and testing can refer to many different situations at all voltage levels. This blog focuses on electrical safety inspection and testing in relation to low voltage systems and includes requirements for electrical installations and also the in-service inspection and testing of electrical equipment.

The best way of dealing with an electrical fire, or more correctly a fire of electrical origin, is to prevent one from occurring in the first place. The cost of correct design, installation and maintenance is minimal when considering the cost of dealing with the aftermath of a fire:- loss of production, temporarily having to rehouse and the potential for loss of life.

The term earthing and bonding for many people often causes confusion, and in some cases a lack of understanding can lead to a very unsafe condition arising. Except in a couple of specific situations where earthing is required for equipment to function correctly, earthing and bonding may seem like an unnecessary effort and expense: after all, equipment will still work without earthing or bonding being in place.
