Hi-Vis Vests 101: What They Are and Why They Save Lives
High-visibility (hi-vis) safety vests are one of the most recognizable pieces of personal protective equipment in the world. Their bright fluorescent colors and reflective strips make workers visible in low-light conditions, near traffic, and in busy industrial environments. But there is more to a hi-vis vest than meets the eye.
What Makes a Vest "High Visibility"?
A true hi-vis vest must meet ANSI/ISEA 107 standards. This means it must use specific fluorescent background materials (yellow-green, orange-red, or red) combined with retroreflective tape that reflects light back toward its source — such as vehicle headlights.
Why Visibility Matters
The National Safety Council reports that being struck by a vehicle is one of the leading causes of workplace fatalities. Workers in road construction, utilities, airports, and warehouses are at constant risk from moving vehicles. A properly rated hi-vis vest dramatically increases a worker's detection distance, giving drivers more time to react.
ANSI/ISEA 107 Performance Classes
- Class 1: Minimum visibility for low-risk environments with slow-moving traffic
- Class 2: Moderate risk environments — most common for road workers and warehouse staff
- Class 3: Highest visibility for high-risk environments with fast-moving traffic or low visibility conditions
Beyond the Vest: Full Garment Options
Hi-vis protection is not limited to vests. Jackets, coveralls, pants, and shirts are all available in ANSI-compliant configurations for workers who need full-body visibility.
Conclusion
A hi-vis vest is a simple, affordable investment that can prevent a fatal accident. RANOVA USA carries ANSI/ISEA 107-certified vests in all performance classes to keep your workforce visible and safe.
