Understanding High-Visibility Safety Apparel: ANSI Class 1, Class 2 & Class 3 Explained

When it comes to workplace safety, high-visibility clothing plays a critical role in reducing accidents and keeping workers seen in hazardous environments. But what do ANSI Class 1, Class 2, and Class 3 actually mean—and how do you choose the right one?

This guide breaks down the differences in a clear and practical way.

What Is ANSI/ISEA 107?

ANSI/ISEA 107 is the American National Standard for high-visibility safety apparel. It defines performance requirements for materials, colors, reflective striping, and garment design to ensure workers remain visible in different risk environments.

High-visibility apparel is divided into three main classes based on the level of visibility needed.

ANSI Class 1: Low-Risk Environments

Class 1 garments provide the minimum level of visibility and are designed for environments where traffic and hazards are minimal.

Common Applications:

• Parking attendants

• Warehouse workers

• Delivery drivers in low-traffic areas

• Off-road or private property work

Key Features:

• Small amount of reflective material

• Usually vests or lightweight shirts

• Suitable for daytime or well-lit conditions

Best for: Situations where workers are clearly separated from traffic and heavy machinery.

ANSI Class 2: Moderate-Risk Environments

Class 2 apparel offers increased visibility and is one of the most commonly used safety classifications.

Common Applications:

• Roadside workers

• Construction crews

• Utility workers

• Survey teams

• Airport ground staff

Key Features:

• Brighter fluorescent colors

• Wider and more reflective striping

• Typically includes safety vests, T-shirts, polos, and hoodies

Best for: Work environments with traffic speeds up to 50 mph or reduced visibility due to weather or lighting.

ANSI Class 3: High-Risk Environments

Class 3 provides the highest level of visibility and is required for extremely hazardous work conditions.

Common Applications:

• Highway construction

• Emergency responders

• Tow truck operators

• Night road work crews

• Heavy equipment operators

Key Features:

• 360° visibility

• Reflective striping on torso, arms, and sometimes legs

• Long-sleeve jackets, coats, hoodies, and rainwear

Best for: High-speed traffic areas, nighttime work, or situations where workers must be visible from all angles.

How to Choose the Right Class of Safety Apparel

When selecting high-visibility clothing, consider:

• Traffic speed and volume

• Lighting conditions (day vs night)

• Distance between workers and vehicles

• Job type and environment

• Local safety regulations

Choosing the correct class not only improves safety but also helps ensure ANSI compliance on the job site.
