What Are OSHA-Approved High-Vis Colors?

The Occupational Safety and Health Administration (OSHA) recognizes fluorescent yellow-green, fluorescent orange-red, and fluorescent red as approved high-visibility (hi-vis) colors for safety apparel. These colors are compliant with the ANSI/ISEA 107 standard, which OSHA references for high-visibility safety clothing requirements.
Fluorescent yellow-green and orange-red are OSHA-approved because they provide maximum visibility in various work environments, reducing the risk of accidents.
Let’s explore these colors and how they meet OSHA standards.
OSHA-Approved High-Vis Colors
1. Fluorescent Yellow-Green
- Why It’s Approved:
Yellow-green is highly visible in daylight, low-light, and natural settings, making it ideal for workers in construction, utilities, and road maintenance. - Best For:
Low-light conditions, natural environments, and overcast weather.
2. Fluorescent Orange-Red
- Why It’s Approved:
Orange-red provides excellent contrast in urban or industrial settings, particularly against asphalt or construction machinery. - Best For:
Daylight conditions, high-traffic zones, and construction sites.
3. Fluorescent Red
- Why It’s Approved:
Red is used in specific emergency or hazardous situations where it signifies danger or urgency. - Best For:
Emergency responders, hazardous material handlers, and high-risk areas.
Why Are These Colors Approved?
1. Maximum Visibility
- OSHA-approved colors provide high visibility under diverse lighting and environmental conditions.
- These colors are easily detected by the human eye, even from a distance.
2. Compliance with ANSI/ISEA 107
- OSHA follows the ANSI/ISEA 107 standard, which specifies performance requirements for high-visibility safety apparel, including the use of these fluorescent colors.
Common Industries Using OSHA-Approved Hi-Vis Colors
| Industry | Common Hi-Vis Color |
|---|---|
| Construction | Fluorescent orange-red for visibility on work sites. |
| Road Maintenance | Fluorescent yellow-green for roadside safety. |
| Emergency Response | Fluorescent red for high-risk, urgent scenarios. |
| Warehousing | Yellow-green to enhance visibility near equipment. |
Additional Safety Features
OSHA-approved hi-vis clothing must include:
- Retroreflective Materials: Reflects light from vehicle headlights, enhancing visibility at night.
- Full Coverage: Vests, jackets, or pants with sufficient fluorescent and reflective material for torso and limb visibility.
In conclusion
OSHA-approved high-visibility colors are fluorescent yellow-green, fluorescent orange-red, and fluorescent red, chosen for their ability to enhance worker safety in diverse environments. These colors meet ANSI/ISEA 107 standards and are widely used in construction, roadwork, and emergency response to reduce visibility-related hazards.
