Understanding ANSI Classes: Choosing the Right High-Visibility Safety Gear
What Are ANSI Classes?
The ANSI/ISEA 107 standard sets guidelines for high-visibility safety apparel to ensure workers are seen in low-light and high-risk environments. These standards classify safety gear based on the amount of reflective material and fluorescent fabric, which determines visibility levels. The higher the class, the greater the visibility and protection.
Class 1: Low-Risk Environments
Class 1 safety apparel is designed for workers in low-risk areas where traffic speeds are under 25 mph and there is plenty of separation between workers and vehicles. This type of gear includes minimal amounts of high-visibility fabric and reflective tape.
Examples of Class 1 Work Environments:
Parking lot attendants
Warehouse workers
Delivery personnel in low-traffic areas
What to Look For:
Class 1 gear often includes hi-vis vests with smaller amounts of reflective material. It’s ideal for jobs where workers aren’t directly exposed to vehicles or heavy machinery but still benefit from added visibility.
Class 2: Moderate-Risk Environments
Class 2 safety apparel is designed for workers in moderate-risk environments where traffic speeds are higher, and visibility is more critical. It requires a greater amount of fluorescent fabric and reflective tape compared to Class 1 gear, making workers easier to spot.
Examples of Class 2 Work Environments:
Road construction crews
Utility workers
Surveyors and traffic management personnel
What to Look For:
Class 2 gear includes vests, jackets, and shirts with wider reflective strips. This gear is designed to stand out in environments where workers are closer to moving vehicles or exposed to moderate hazards.
Class 3: High-Risk Environments
Class 3 safety apparel offers the highest level of visibility and is designed for workers operating in high-risk environments where traffic speeds exceed 50 mph, or visibility is severely reduced. This gear covers the most body surface area with reflective and fluorescent materials.
Examples of Class 3 Work Environments:
Highway construction crews
Emergency responders
Tow truck operators and heavy equipment workers
What to Look For:
Class 3 apparel typically includes full-body coverage like jackets, overalls, or rain gear. Reflective strips are placed on the arms and legs to ensure workers are visible from all angles, especially at night or in harsh weather conditions.
Choosing the Right Gear for Your Needs
Selecting the right ANSI class comes down to understanding the specific hazards of your work environment. Consider factors like traffic speed, lighting conditions, and how close workers are to vehicles or heavy equipment. For lower-risk jobs, Class 1 gear might be sufficient, but for highway work or nighttime projects, Class 3 apparel is essential.
It’s also worth noting that ANSI standards help ensure compliance with safety regulations, so choosing the proper gear isn’t just about protection—it’s about staying in line with industry requirements.
Why It Matters
High-visibility safety gear isn’t just a box to check—it’s an investment in worker safety and jobsite efficiency. By understanding the ANSI classes and selecting the appropriate gear, you’re ensuring your team is protected, visible, and ready to tackle the job with confidence.
Stay safe, stay visible, and make safety a priority on every jobsite.
