Arc Flash Services

We are an experienced arc flash consultancy specialising in arc flash studies, risk assessment and management of arc flash. We follow the guiding principles of Predict, Prevent and Protect and have services to support you from initial hazard identification through to a complete arc flash management strategy.

We are formally trained in the application of the internationally recognised IEEE 1584 methodology for calculating the arc flash incident energy. We can determine results for your site and advise on practical ways to reduce incident energy and protect your people and equipment.

What is an Arc Flash?

An electrical arc flash happens when two conducting surfaces inadvertently come into contact, often during testing or maintenance when a tool can be dropped or a mechanism becomes misaligned. A large electrical fault current flows, forcing the surfaces apart and leading to an electrical arc. This releases a huge amount of energy which can cause serious injury, or death, or result in serious equipment damage.

Should you be addressing Arc Flash?

Arc flash is identified in the United Kingdom's Electricity at Work Regulations 1989 as one of the hazards of working with electricity. As such, site owners and operators have a legal duty to understand and control the risks posed by arc flash.

Our Approach

Predict

Where might arc flash occur, who could be hurt, and how big could the impact be?

Predicting arc flash is all about understanding your site electrical equipment and the types of activities taking place on or near it.

We will gather information about your equipment, model your network and use the IEEE 1584 methodology to calculate incident energy as part of an Arc Flash Study. Combined with an understanding of the likelihood of arc flash we can then risk assess your site.

Prevent

What mitigation measures are appropriate to reduce the risk from Arc Flash?

We can assess your existing equipment to see if improvements are possible. If this isn’t sufficient we can advise on engineering solutions to reduce the arc flash hazard level taking into account the practical aspects of your site and the activities you do.

We follow the hierarchy of controls to determine the measures with the highest integrity.

Protect

How do we protect people and equipment from arc flash?

Once you know what the risks are and the mitigation measures needed, you must communicate this to those responsible for work on site so they can make informed decisions.

We can advise on equipment labelling, updates to permits and procedures, and selection of PPE appropriate to your hazard level and activities, as well as delivering training and education.
