Having spent 10 years in the fire protective clothing industry, I assumed marketing Hi-Vis garment was going to be easy. Turns out, it’s far more complex than I had anticipated. While we tend to think only in terms of the visibility factor, it is important to remember that the latest ANSI/ISEA 107-2015 standard covers both basic design and performance of high visibility in work garments. The emphasis regarding high visibility garments has traditionally been on the photometric requirements -- the minimum amount of component materials, colors, and placement to create garments for enhancing the visibility of workers. Let’s review some basics on this subject.
For both garment and trim, there are three fluorescent colors: yellow-green, orange and red. The standard clearly charts out the amount of background material, retroreflective material (and width) based specifically on the garment type, designation, and class.
