Is Arc Flash a UK Legislative Requirement?

Electrical Safety UK specialise in carrying our arc flash studies for our many clients. One of the things that comes 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.

It is commonly understood that there are specific regulations which identify the need to carry out a suitable and sufficient risk assessment and to put measures in place to protect those who could be put at risk is mandated. The Electricity at Work Regulations 1989 and The Management of Health and Safety at Work Regulations 1999 are specific in these areas. Read more about the specific regulations here.

But where’s the evidence?

Paul Hopton, Principal Consultant at Electrical Safety UK, recently carried out extensive research to prove that the HSE are actively prosecuting companies for failing to protect and mitigate the risk where Arc Flash is the cause.

There are two types of enforcement notices that have been issued by the HSE that refer to Arc Flash, Improvement Notices and Prohibition Notices. There have been 37 Enforcement Notices issued in the past few years by the HSE that concern Arc Flash. The Enforcement Notices cite the following Legislation and Regulations:

  • Health and Safety at Work Act
  • The Electricity at Work Regulations
  • Mines Regulations 2014
  • Management of Health & Safety at Work Regulations 1999
  • Construction (Design and Management) Regulations 2015

At the end of this article you will find specific research including Prosecution examples and the breaches identified.

OK, so there is legislative requirement, but who is responsible?

If we now accept that there is a UK legislative requirement that Arc Flash Risk should be managed and controlled, who is going to be held responsible for ensuring that this happens? The Electrical Duty Holder is very likely to held to account, even if they have delegated some of their responsibilities to other persons within their business. And so two questions should be raised within every company that may have this risk;

  • Who is the Electrical Duty Holder in your business?  
  • Do they know that they should be managing Arc Flash Risk?

What does Arc Flash Risk Management Good Practice look like?

At Electrical Safety UK we have been extremely successful over the years in assisting clients in understanding what good practice looks like when it comes to managing the Arc Flash Risk. This is evident within our case studies following the completion of this work. 

In brief, good practice can be achieved by implementing certain tasks:

  1. Calculate the Arc Flash Incident Energy Levels and Arc Flash Boundary Distances on each piece of equipment that is connected to your Electrical Distribution Network.

ESUK can help you to limit this scope by applying our knowledge and experience of which parts of your network will be higher hazard, and which parts will be low hazard.

  1. Label the equipment with the calculated values and recommended Personal Protective Equipment (PPE) that could be used to mitigate the risk.

ESUK can help to determine a suitable PPE policy for your network/Company based upon the results of the calculations.

  1. Reduce the arc flash incident energy levels.

ESUK’s standard arc flash study includes recommendations on how to do this, if practicable.

  1. Carry out task-based arc flash risk assessments on the equipment with the highest levels of incident energy. 

ESUK are the only Company in the UK that can offer City & Guilds Assured Practical Arc Flash Risk Assessment Training or we can complete the risk assessments for you.

  1. Give your staff the competence to understand Arc Flash Risk and how they can mitigate it.

ESUK offer arc flash awareness training that can be customised to meet your Company’s needs.

  1. Ensure visitors and contractors on your site understand their responsibilities in ensuring that your arc flash risk is managed appropriately.

ESUK can help you integrate your arc flash risk management strategy into your Electrical Safety Rules and Electrical Safety Management System.

Therefore, the initial investment in critical Safety Management can be justified against any significant prosecution costs, loss of revenue, brand damage. By ensuring Good Practice to mitigate or reduce the risk of Arc Flash in any company will show significant return on investment.

The Enforcement Notices that cite the Health and Safety at Work Act refer to breaches of the following provisions:

2/1: It shall be the duty of every employer to ensure, so far as is reasonably practicable, the health, safety and welfare at work of all his employees.
