Low Voltage, low Arc Flash risk: Arc Flash myths

Low Voltage, low Arc Flash risk: Arc Flash myths

It’s all too common for people to think Arc Flash risks are only presented to those working in high voltage environments. But that’s just not true.

One of the main problems of this widespread belief is that Arc Flash training and PPE equipment tends to be focused only on those working in high voltage working environments.

This means other employees are left completely unprotected and unprepared for potential arc flash risks in the event of an Arc Flash incident.

THE FACTS ABOUT ARC FLASH RISKS

Any power supply equipment in commercial buildings, factories and data centres, for example, can pose an Arc Flash risk. Short circuit fault currents in small distribution transformers can also cause an Arc Flash incident.

In fact, there can be significant Arc Flash risks for many employees, not just those working directly on electrics. We reported for example on arc flash risk that materialised when an operative who struck a 120 CNE 3 Phase low voltage cable with a pneumatic drill which triggered an Arc Flash.

While correct PPE can save workers from life-changing or potentially fatal injuries, it’s only part of the Arc Flash risk management solution.

With proper Arc Flash risk assessments and effective training stemming from a good overall safety culture in your workplace, Arc Flash risks can be substantially reduced helping to make sure all your workers will go home to their families after their shifts have ended.
