Where they are worn
- Under arc flash switching suits, coveralls, jackets and trousers as a flame-resistant base layer
- In switchrooms, substations and live working environments where the risk assessment calls for flame-resistant clothing
- By utility crews, data-centre engineers, pharmaceutical plant staff and electrical contractors
These are underwear, not outer protection. Pair them with garments from our arc flash protection range selected to match the incident energy in your risk assessment. If your team is new to the hazard, our guide on what arc flash is is a useful starting point, and protection only holds if garments are cared for correctly, so follow the laundering and care guidance.
FAQs
What standards are these boxers approved to?
The fabric is approved to EN ISO 14116 Index 3 for limited flame spread and EN 1149-5 for electrostatic properties. The fabric itself is tested to EN ISO 11612 A1 B1 C1 and EN 61482-1-2, the box test for electric-arc hazards. OEKO-TEX certification covers harmful substances.
Can I wear these instead of arc flash outer clothing?
No. These are a flame-resistant base layer. Outer protection must be selected from our arc flash protection range based on the incident energy identified in your risk assessment or arc flash study. Underwear adds a layer of protection; it does not replace rated outer garments.
