Description
The Portwest flame-resistant waterproof trousers offer excellent protection for professionals working in high-risk and wet environments. These multi-standard trousers combine high visibility with high-quality safety features to protect the wearer against various workplace hazards. Thanks to its robust construction, this garment is specifically designed for heavy industrial applications where flames, static electricity, and rain pose a daily risk.
For which activities and sectors are these flame-resistant waterproof trousers most suitable?
These trousers are ideally suited for outdoor work in the petrochemical, utility, and offshore industries where exposure to rain, flames, and static electricity occurs.
The trousers comply with the EN ISO 20471 Class 1 standard for high visibility, ensuring you stand out while working along the road or on dark construction sites. The orange version also meets the RIS 3279 TOM standard for the rail industry, making this version specifically suitable for rail workers who need to operate safely in all weather conditions.
What do the EN 343 and EN ISO 14116 standards mean for these flame-resistant waterproof trousers?
The EN 343 Class 3:3 X standard guarantees the highest class of waterproofness and breathability, keeping rainwater out while effectively wicking away perspiration.
The EN ISO 14116 Index 3 standard means the fabric is resistant to heat and flames, preventing flame spread and ensuring the material does not melt upon contact with fire. This provides crucial protection in environments with explosion or fire risks, unlike standard rainwear which catches fire easily.
