Flame Retardant Hi Vis Clothing for Higher-Risk Working Environments
Hi vis flame retardant clothing is widely used in workplaces where visibility is important but standard hi vis garments alone are not enough. These garments are commonly chosen for rail infrastructure, utilities, roadside operations, engineering, industrial maintenance and other higher-risk environments where workers may need protection against heat, flame or related hazards alongside high visibility performance.
If you need help understanding visibility classes and workplace garment requirements, read our EN ISO 20471 guide and our explanation of Class 1, Class 2 and Class 3 hi vis clothing.
Choose Between FR Jackets, Trousers & Coveralls
Our range includes hi vis flame retardant jackets for visible protective outerwear, hi vis flame retardant trousers for lower-body protection and hi vis flame retardant coveralls for more complete body coverage in demanding site environments.
