EVs and the DC Hazard: Tyndale FRMC® CAT 2 Outfit in a DC Arc

June 13, 2023

With the rapid growth of electric vehicles (EVs), and the infrastructure needed to support them, so too grows the importance of understanding the direct current (DC) arc hazard. That’s where Tyndale comes in! This series lays out the differences between the alternating current (AC) arc hazard and its lesser-known DC counterpart and demonstrates – through first-of-its-kind real-world video footage – the power of DC arcs. Follow along to learn more and witness firsthand the life-saving difference the right arc-rated (AR) clothing makes in the face of a DC arc.

In our previous episode, we pushed an NSA TECGEN® CAT 2 AR shirt and a pair of AR jeans to their limits by subjecting them to a thrilling DC arc. And they passed with flying colors, effectively extinguishing fire and eliminating any breakopen risks.

Fasten your seatbelts as we put our very own CAT 2 Tyndale AR FRMC® long sleeve shirt in face of a DC arc. Will it prove to be just as remarkable as the NSA TECGEN®? See the action firsthand:

This captivating video showcases the resilience and performance of a popular choice among professionals – the Tyndale FRMC® shirt and FRMC® jeans – as they face a 9.4 cal DC arc head-on. While the shirt was slightly carbonized and covered in molten copper, the garments did their job - protecting the worker from the hazard. The garments stood up to the challenge with remarkable durability.

This video shows why it’s so important to wear arc-rated (AR) clothing and appropriate PPE when there is an arc hazard in your job environment. In fact, in most of the injuries and fatalities we see, the outcomes were preventable – caused by people wearing fuel. This video shows that the DC arc hazard is no exception. Don’t leave home without your last line of defense.

Next up, we test an EBT AR garment as it’s exposed to a DC arc with more energy than it’s approved to take. Stay tuned to see if there is more or less breakopen compared to AC arcs of the same energy level.
