The American National Standards Institute (ANSI) sets guidelines for the design and performance of high - visibility clothing to ensure the safety of workers in various industries. ANSI class 2 and class 3 high visibility gear are two of the most common classifications, each with its own specific requirements and intended use.
ANSI class 2 high visibility gear is designed for workers who need to be visible in situations where there is a significant amount of background complexity and where the worker needs to be seen from a distance of at least 1280 feet. This class of gear is typically used in work zones where traffic speeds are less than 25 mph, such as parking lots, school zones, and some construction sites with low - speed traffic. Class 2 high visibility gear includes items such as vests, shirts, and jackets. These garments must have a minimum of 775 square inches of background material and 201 square inches of reflective material. The background material is usually a bright fluorescent color, such as yellow, orange, or lime green, and the reflective material is applied as strips or patches to the garment.
The reflective strips on ANSI class 2 high visibility gear must be at least 1.375 inches wide and must be placed in specific locations on the garment to ensure maximum visibility. For example, vests must have reflective strips on the front and back, as well as on the shoulders. The design of class 2 gear is focused on providing a good balance between visibility and comfort, allowing workers to move freely while still being easily seen.
ANSI class 3 high visibility gear, on the other hand, is designed for workers who need to be highly visible in situations where there is a high level of background complexity and where the worker needs to be seen from a distance of at least 1280 feet, even in low - light conditions. This class of gear is typically used in work zones where traffic speeds are greater than 25 mph, such as highways and major roads. Class 3 high visibility gear includes items such as full - body suits, jackets with sleeves, and pants with reflective stripes. These garments must have a minimum of 1240 square inches of background material and 310 square inches of reflective material.
The reflective strips on ANSI class 3 high visibility gear are wider than those on class 2 gear, typically at least 2 inches wide. They must also be placed in more prominent locations on the garment, such as around the arms, legs, and torso, to provide 360 - degree visibility. The design of class 3 gear is more substantial than class 2 gear, providing greater coverage and visibility to workers in high - risk environments.
In addition to the differences in the amount of background and reflective material, ANSI class 3 high visibility gear may also have additional features, such as reflective tape on the sleeves and legs, to enhance visibility. It is also often made from more durable materials to withstand the harsh conditions of high - speed work zones.
When selecting high visibility gear, it is important to consider the specific requirements of the work environment and the traffic conditions. Workers in high - speed traffic areas should wear ANSI class 3 high visibility gear, while those in lower - speed areas may be able to use class 2 gear. Employers are responsible for ensuring that their workers wear the appropriate ANSI - compliant high visibility gear to meet safety regulations and protect their workers from accidents.
In conclusion, ANSI class 2 and class 3 high visibility gear are designed to meet different visibility needs in various work environments. Understanding the differences between these two classes is crucial for ensuring the safety of workers in high - risk areas.
