The Portwest FR448 flame-resistant trousers are specifically designed for professionals who require reliable protection against thermal hazards during their daily work. These work trousers are highly suitable for welders and industrial personnel in high-risk environments. Thanks to high-quality materials, this model combines excellent heat and flame resistance with a comfortable fit, allowing you to remain optimally protected and perform throughout the entire workday.
For which specific tasks and sectors are these flame-resistant trousers from Portwest suitable?
These flame-resistant trousers are ideal for heavy-duty welding, metalworking, and industrial work in ATEX environments where welders are exposed to extreme heat and welding spatter.
The trousers offer certified protection against radiant, convective, and contact heat, as well as molten metal splashes. Thanks to their anti-static properties in accordance with the EN 1149-5 standard, this model is also safe to use in explosion-risk environments where static discharges must be prevented at all times to ensure safety.
What do the EN ISO 11611 and EN ISO 11612 standards mean for these flame-resistant trousers?
The EN ISO 11611 Class 2 certification means that these trousers are certified for heavy welding techniques where significant welding spatter and radiant heat are released.
The EN ISO 11612 standard guarantees that the clothing protects against heat and flames. The specific codes A1+A2 indicate limited flame spread, while B1, C1, E3, and F1 represent performance against convective heat, radiant heat, molten iron splashes, and contact heat, respectively. This ensures a broad and certified level of safety during high-risk industrial operations.
The trousers offer extra comfort due to the elasticated waistband, two-position kneepad pockets, an extendable hem, and eight practical storage pockets, including a rule pocket.
