EVs and the DC Hazard: NSA TECGEN® CAT 2 Outfit in DC Arc

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 last two episodes, we tested non-protective polyester/cotton blend and 100% cotton fabrics to see how they perform in the face of a DC arc. But how do popular arc-rated (AR) garments perform in DC arcs at or near their arc ratings? Follow along with our next few episodes to find out.

Get Ready for the Test

First up, we put an NSA TECGEN® CAT 2 AR shirt, worn with AR jeans, to the test in a DC arc. Watch to see the difference the right AR clothing and PPE make:

As expected, the AR clothing proves its mettle, eliminating fire and breakopen risks. With unwavering fortitude, the garment does its job flawlessly – shielding the wearer and insulating him from the hazard. In fact, this worker would not have experienced any burn through the garment at all. It's a compelling demonstration of the life-saving power of AR clothing.

Don’t Miss Out!

Watch the captivating video above, capturing the action from various angles and distances. Witness the stark contrast between this remarkable outcome and our previous tests, where manikins dressed in flammable non-AR fabrics suffered severe body burns of over 50% and 60% respectively.

This video shows why it’s so important to wear 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 a popular AR Tyndale FRMC® shirt and FRMC® jeans in a 9.4 cal DC arc.
