Why do Arc Flash Calculations

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.

Arc Flash Risks could exist within Hospitals and Health service environments

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 and Arc Flash Risk within The Rail Industry

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.

Solar Farm

Solar Farms

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.

Arc Fault Detection Devices (AFDDs)

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.

Electrical Safety Management System – Arc Flash

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.  

The Importance Of Data Collection For Arc Flash Analysis

Do I Have To Wear Arc Flash PPE?

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 …

Arc Flash Protection – PPE For Electrical Professionals

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.

Arc Flash Legislative Requirements And The Role Of Electrical Duty Holders

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.

2018 IEEE 1584 Update – Introduction To The Changes

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.

Is Carrying Out An Arc Flash Study A Legal Requirement In The UK?

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.
