Class 1 is designed for workers who are exposed to low-risk traffic conditions, typically on the side of the road. Class 2 is suitable for medium-risk traffic areas where workers may encounter faster-moving vehicles, such as on construction sites. Class 3 is intended for high-risk environments where workers are exposed to high-speed traffic, such as on highways or airport runways.

High visibility clothing is typically made from lightweight, breathable materials such as polyester or nylon. These materials are resistant to fading and abrasion, ensuring that they remain reflective even after repeated washings. The fabric is often treated with a water-repellent coating to protect workers from rain and moisture. Some high visibility clothing may also incorporate flame-retardant materials for added protection against industrial hazards.

Look for clothing that is certified by the American National Standards Institute (ANSI) or the International Standards Organization (ISO). These organizations have established rigorous standards for the design, performance, and testing of high visibility clothing. Certified clothing will meet or exceed the minimum requirements for visibility and reflectivity, ensuring that workers are adequately protected in hazardous environments.

There are a variety of accessories available to complement high visibility clothing. These include items such as hats, gloves, vests, and safety glasses. Accessories are designed to enhance the visibility of workers in different work environments. For example, hats with reflective brims provide additional protection from the sun and rain, while vests and jackets offer extra warmth and insulation in cold weather. Safety glasses with reflective frames help to keep workers safe from flying debris and other hazards.
