"Electric arc is a complex phenomenon"<br />

• Open air arc - The most widely understood<br />

• Arc-in-a-box - Used as a method of testing Arc<br />

garments in the EU<br />

• Ejected Arc – projectile arc plasma<br />

• A tracking arc - Most common at higher voltages,<br />

arc plasma conducts on skin or through clothing<br />

In lab testing, we control movement of the arc for the sake<br />

of replication, but in reality, from 480V higher, the openair<br />

arc can quickly turn into an ejected arc or a tracking<br />

arc.<br />

Creating workwear that can protect against arc exposure<br />

has meant working closely with fabric manufactures and<br />

wearers as we sought to understand how we can mitigate<br />

this hazard whilst not compromising on comfort. In doing<br />

so we have design our Tecwear Arc Protect clothing<br />

range to be able to withstand extreme temperatures of up<br />

to 12,000°C, explosive forces, emission of plasma, fast<br />

moving debris and hot liquids.”<br />

To ensure that our Tecwear Arc Protect coveralls,<br />

jackets, trousers and base layers meet British and<br />

European safety standards we manufacture these<br />

garments under Article 11b and subject all our Arc<br />

protection garments to strict BTTG testing and<br />

certification. This means Tecwear Arc protection<br />

garments are accredited and conform to the latest IEC<br />

61482 – Protective Clothing against Thermal Hazards of<br />

Electric Arc, adding that much needed peace of mind.<br />
