Standards, Regulations & Resources

How do PSE2 comply with the relevant standards?

At PSE2, we adhere to industry standards and regulations to ensure compliance and promote safety.

The power system analysis tools that we employ comply with the requirements of IEEE Standard 1584 and NFPA 70E.  Click to expand the following sections and learn more

IEEE Standard 1584
This is a mature American standard entitled “IEEE Guide for Performing Arc-Flash Hazard Calculations” and contains equations for the calculation of arcing current, incident energy and arc flash boundary.
The long-established “Standard for Electrical Safety in the Workplace” in the USA contains guidance on arc-rated clothing and PPE, arc flash warning label content and electric shock protection boundaries.
The Management of Health and Safety at Work Regulations 1999
These UK regulations place a legal duty upon employers to take a proactive approach to identifying and controlling risks, providing a safe working environment and ensuring the health and safety of employees in the workplace.
Employers must identify and evaluate the risks to the health and safety of employees and others who may be affected by their work activities and take steps to control or mitigate those risks through a formal risk assessment process. For electrical work, this should include assessing the risk posed by arc flash hazards, in addition to the hazard presented by electric shock.
Health and Safety (Safety Signs and Signals) Regulations 1996
This piece of UK legislation ensures effective use of safety signs and signals to promote health and safety in workplaces. Arc flash hazard warning labels produced for UK workplaces need to comply with the requirements of this legislation in relation to warning and prohibition signs.
