The 3 Key Classes of Safety Visibility Apparel (And When to Use Them) by ANSI Anyone who works near traffic or heavy machinery knows (or should know) that they can't set foot on the job site unless they're wearing high visibility safety apparel (HVSA). Workers across very different industries are required to use HVSA, including: Construction workers Workers in heavy industry Employees responsible for retrieving shopping carts from a parking lot Truck drivers Safety wardens in office buildings (used in the event of an emergency) Senior management visiting the factory floor or a warehouse A lot of workers need to wear HVSA, but not all hi-vis gear is the same. Different jobs and working conditions will require different levels of visibility and, therefore, different classes of hi-vis apparel. HVSA Regulations In the United States, hi-vis is defined and categorized by ANSI/ISEA 107-2015 American National Standard for High-Visibility Safety Apparel and Accessories. In Canada, CSA Z96-15 High Visibility Safety Apparel applies instead. The regulations ensure that the right combination of materials and design specifications work together to maximize the user's visibility. Hi-Vis Clothing: What it Is and Why It’s Crucial for Safety High visibility clothing is apparel that has fluorescent or highly reflective elements. These elements make the most of any available light, helping the workers who are wearing this apparel to be visible against any background and in any conditions, including low light and even darkness. This increased visibility is critical for worker safety, particularly when they are working around moving vehicles and equipment. From small rural roads to huge runways at international airports, hi-vis clothing plays an important role in a comprehensive safety program. Industry standards help explain how to best protect your team and that starts with an understanding of ANSI. It’s Important for Safety Managers and Workers to Know ANSI The American National Standards Institute (ANSI) is a federation of both safety standard creators and users. It is not a government agency, although it works closely with the United States government. ANSI manages the voluntary safety standards system in the United States and serves as the official United States representation in international safety standards organizations. ANSI publishes a voluntary industry consensus standard, ANSI/ISEA 107, which is the authoritative document on the required design, performance, and materials for high-visibility safety apparel and personal protective equipment (PPE) in the United States. This standard is integrated into the U.S. Department of Transportation Federal Highway Administration (FHWA) regulations, the Manual on Uniform Traffic Control Devices (MUTCD), and many other relevant worker protection standards. The fifth edition of this standard, ANSI/ISEA 107-2020, breaks down high-visibility clothing into three types and four performance classes. Here’s how to make sure that you are interpreting this updated standard correctly and selecting the right high-visibility clothing for your team and their unique needs. Lighting Conditions In daylight conditions, hi-vis gear relies on fluorescent materials to reflect invisible ultraviolet light from the sun. Unlike other types of apparel, it magnifies its visibility. In low-light conditions, fluorescent colors aren't as effective. That's where retroreflective materials come in. These materials reflect the light from artificial light sources like flashlights or vehicle headlights. In daylight conditions, however, retroreflective strips are just as visible as any other material and don't help the user stand out. Since working conditions can change, and not every employee will remember to switch their daylight HVSA for low light HVSA, many items combine both types of visibility. Using the special combined-performance retroreflective material, HVSA can offer both retroreflective and fluorescent properties. The Three Classes of HVSA ANSI/ISEA 107-2015 and CSA Z96-15 identify three classes of high-visibility safety apparel . It’s important to recognize that the three classes do not describe particular garment types, like jackets, overalls, or vests. Rather, they specify the amount of reflective material, the width of the reflective material (usually stripes), and the amount of background materials. A parallel classification also designates the clothing’s work purpose: Type O: Off-road Type R: Roadway or temporary traffic control Type P: Public safety activities OEM printing logo personalized reflective safety Vest In addition, the 2015 standard requires that all materials used in making HVSA clothing include labeling that identifies the garment by performance class and type, as well as its flame resistance characteristics. Together, these HVSA classes and designations are summarised as follows: Class 1 Class 1 provides the lowest recognized coverage and visibility. It is meant for lower-risk environments. For example, a light vest made entirely out of vertical (front) and X-shaped (rear) retroreflective bars and worn over top of regular work clothes would be used in relatively safe situations where there is plenty of space between workers and slow-moving traffic. A low-risk workplace might require Class 1 or Class 2 apparel, depending on circumstances, such as the amount of and proximity of traffic, weather, lighting, and potential for distraction. Examples of work that require Class 1 or Class 2 apparel include: Directing vehicles to park or service locations Shopping cart collection in parking areas Warehouse operations Shipping and Receiving Class 2 Class 2 provides moderate body coverage and superior visibility. These include fluorescent orange or yellow/green jackets, bib overalls, and vests incorporating retro-reflective bands. Medium-risk jobs may require Class 2 or Class 3 clothing, depending on the circumstances and environmental conditions. Examples of work that requires Class 2 or Class 3 apparel include: Roadway construction, utility, forestry, or railway work Survey crews School crossing guards Parking attendants and toll gate workers Airport baggage handling and ground crews Emergency response Law enforcement Accident site investigation Class 3 Class 3 provides the greatest body coverage and visibility under poor lighting conditions and at farther distances. High-risk work might require Class 2 apparel during the daytime and Class 3 during the night or low-light conditions. These classes are worn where there is machinery or vehicles moving in close proximity or at higher speed and where workers must be conspicuous through a full range of body motions at a minimum of 1,280 feet. Jobs in this category include: Roadway construction Utilities Survey crews Emergency response Road assistance Flagging crews Towing operations HVSA Training As with all safety equipment and protocols, employees must be trained in the use and care of HVSA. This includes wearing the materials correctly to ensure the retroreflective bands are visible, taking care of and cleaning the apparel, and choosing sizes that fit the individual’s body type with enough room for safe movement and carriage of tools without being overly bulky, heavy, or impeding safe motion. Training and consultation with a company safety officer is always essential to ensure that employees remain safe and that their employers remain in compliance with local or federal safety regulations. Conclusion It's important to remember that the proper selection of safety visibility apparel depends on the specific work environment and the level of risk associated with the job tasks. ANSI standards are regularly updated, so it's advisable to consult the latest ANSI/ISEA standards or official sources for the most up-to-date information on this topic.
