Frequently Asked Questions About FR Winter Trousers
Q: How long do flame-resistant properties last? A: The Portwest PW3 uses inherent FR technology. These trousers maintain flame resistance through regular washing – the properties don't diminish with laundering like treated fabrics do.
Q: Are these trousers suitable for arc flash environments? A: Yes. With ATPV and ELIM ratings, the PW3 provides protection in arc flash incidents. However, always verify specific workplace hazard assessments determine appropriate PPE.
Q: What's the difference between Class 1 and inherent FR? A: Class 1 FR is the highest classification for flame-resistant workwear. Inherent FR means the fiber itself is flame resistant, not a treatment applied to the surface.
Q: Can I wear these in ATEX Zone 1 environments? A: Yes, the PW3 is specifically designed for ATEX environments and meets necessary non-magnetic requirements.
Q: How do I care for FR winter trousers? A: Wash according to manufacturer instructions (typically 40-60°C). Avoid fabric softeners and bleach, which can compromise FR properties.
