Workers near traffic or moving equipment need to remain recognizable against their surroundings. High-visibility workwear can help drivers and equipment operators notice them sooner when lighting or complex backgrounds make workers harder to see.

Color matters, but workplace hazards, garment classification, fit, and applicable requirements should guide apparel selection.

ANSI/ISEA 107-2020 permits three fluorescent colors for compliant high-visibility safety apparel:

  • Fluorescent yellow-green
  • Fluorescent orange-red
  • Fluorescent red

The standard does not assign each color to specific jobsites or rank one as safer than another. Employers should choose an approved color that provides suitable contrast with the work environment and meets any regulatory, contractual, or site-specific requirements.

How to Choose High-Visibility Workwear

Begin with the hazards employees face, not a preferred color or garment style. Evaluate where employees work, what vehicles or equipment operate nearby, and how the environment may affect worker recognition.

1: Assess the Work Environment

Look at the backgrounds workers encounter throughout the shift. Machinery, stored materials, traffic-control devices, buildings, and natural surroundings may all affect contrast. A color that stands out in one area may be less noticeable in another.

When possible, review the apparel in the actual work environment during daylight, at night, and under the artificial lighting employees encounter.

2: Determine the Appropriate Type and Performance Class

ANSI/ISEA 107-2020 classifies high-visibility safety apparel by type and performance class. Type reflects the expected work setting:

  • Type O: Off-road environments where workers face hazards from moving vehicles or equipment but are not exposed to roadway traffic.
  • Type R: Roadway environments where workers are exposed to traffic.
  • Type P: Public-safety environments for emergency responders and law-enforcement personnel.

Performance class indicates the amount of visible material and body coverage the garment provides:

  • Class 1: Provides the minimum required amount of visible material and applies only to Type O apparel.
  • Class 2: Provides more visible material and coverage than Class 1.
  • Class 3: Provides the greatest visible-material coverage and helps make the wearer recognizable as a person.

Select the appropriate type and class based on the workplace hazard assessment and any requirements that apply to the work.

3: Confirm the Garment’s Features

The following chart can help safety managers compare high-visibility workwear without relying on color alone.

Selection factorWhat to checkWhy it matters
Environmental contrastBackgrounds, machinery, signs, and changing conditionsHelps identify a distinguishable approved color
Apparel type and classANSI/ISEA type and performance-class markingsConnects the garment to its intended setting and level of coverage
Visible materialsFluorescent background and retroreflective materialSupports recognition under different lighting conditions
LabelingStandard edition, type, class, and care informationHelps verify the finished garment’s classification
Fit and coverageSizing, closure, and unobstructed visible materialPoor fit or covered material may reduce visibility

Fluorescent background material supports daytime visibility. Retroreflective material returns light toward its source, which can help drivers see workers when headlights illuminate the garment.

Employers should also consider compatibility with other required protective clothing. Employees exposed to flash-fire or electric-arc hazards may need flame-resistant work clothes that meet applicable high-visibility requirements. Confirm that the complete clothing system addresses every identified hazard.

High-Visibility vs. Enhanced-Visibility Apparel

High-visibility safety apparel meets ANSI/ISEA 107-2020 requirements for materials, design, visible-material coverage, classification, and labeling. When selecting ahigh-vis safety vest, check the label for the applicable standard, type, and performance class.

Enhanced-visibility shirts and pants may use bright colors, reflective accents, or contrasting materials to make workers easier to see. Unlike high-visibility safety apparel, they are not classified as ANSI/ISEA 107-compliant and should not be used when the job requires compliant high-visibility clothing.

Maintaining High-Visibility Workwear

Fading, dirt, and damage can reduce a garment’s effectiveness, so employers need clear inspection and replacement procedures. Employees should report:

  • Faded fluorescent material
  • Damaged or missing reflective material
  • Tears that affect coverage or fit
  • Permanent stains or contamination
  • Closures that no longer hold the garment in place

Follow the manufacturer’s washing and drying instructions. Improper laundering can damage fluorescent and reflective materials. A work uniform rental program can help employers maintain consistent laundering, inspections, and replacement procedures across the workforce.

Frequently Asked Questions

Neither color is universally better. Select an approved color that provides suitable contrast with the work environment and meets applicable regulatory, contractual, or company requirements.

No. ANSI/ISEA 107-2020 permits fluorescent yellow-green, fluorescent orange-red, and fluorescent red, but the material must meet the standard’s technical color requirements. Colors such as neon pink, fluorescent blue, neon purple, and fluorescent white are not approved. The finished garment must also meet requirements for materials, design, coverage, classification, and labeling.

Class 3 apparel requires more visible material and greater body coverage than Class 2 apparel. Select the class based on the hazard assessment and requirements that apply to the work.

Replace a garment when fading, damage, wear, or permanent contamination limits its intended visibility. Follow the manufacturer’s guidance and establish a process for employees to report problems promptly.
