About This Item


Full Description

The need to be seen is recognized as a critical issue for worker safety. Low visibility is a serious hazard for all workers who must perform tasks near moving vehicles or equipment. Workers must be visible to vehicle operators in all lighting conditions and against complex environmental backgrounds. The sooner a vehicle operator sees a pedestrian worker, the longer the operator has to avoid an incident. High visibility safety apparel and accessories dramatically enhance worker visibility.

This new edition consolidates the requirements of ANSI/ISEA 107-2010 and ANSI/ISEA 207, American National Standard for Public Safety Vests in an effort to establish a single, comprehensive document that considers all occupational tasks. While the standard continues to present three performance classes of garments based on the amount of visible materials and design attributes incorporated into the final configuration, it also identifies garment types based on expected use settings and work activities being performed. These are designated as off-road (type O), roadway and temporary traffic control (type R), or public safety activities (type P).

Fit and comfort of high-visibility safety apparel play an important role in worker acceptance of wearing these items as part of their daily activity. While previous editions provided some freedom in design that resulted in smaller sized garments capable of meeting the standard's requirements, specifiers and users wearing garments classified as Performance Class 2 under the ANSI/ISEA 107-2010 standard edition had expressed concern regarding appropriately fitting compliant garments for smaller sized workers. Garments that are not properly sized to fit can expose workers to catch hazards or interfere with other protective gear, potentially compromising worker safety. In response, the ANSI/ISEA 107-2015 standard edition now includes provisions for Type R Performance Class 2 and Performance Class 3 garments in the smallest size offered to utilize a reduced amount of background material to allow for sizing more appropriate for smaller workers. It is stressed that these reduced amounts are intended to address the smaller sized workers' needs specifically, that only the smallest size offered for any one garment be allowed to deviate from the stated minimum and that the resulting configuration using these amounts be consistent with the other sizes for that particular garment.

Additionally and in recognizing the growing use of high-visibility accessory items such as arm bands or headwear, the standard defines minimum material requirements for these accessories. New labeling requirements will identify the garment by performance class, type and by its flame resistance characteristics as defined in the standard. ANSI/ISEA 107-2015 also expands the examples of garment configurations to illustrate compliant and non-compliant designs.

This standard specifies performance requirements for high-visibility safety apparel and accessory PPE. For the purpose of this standard, the term "high-visibility safety apparel (HVSA)" shall be used to mean apparel and accessory PPE intended to provide conspicuity to the user in hazardous situations under any light conditions by day and under illumination by vehicle headlights in the dark or other low light conditions.

Performance requirements are included for color, retroreflection, and minimum areas of retroreflective and combined-performance materials, as well as the recommended configuration of the materials. Performance requirements are also provided for the color, physical properties, and minimum areas of background materials used in the construction of HVSA and accessories. Test methods are provided in the standard to ensure that a minimum level of visibility is maintained when garments are subjected to ongoing care procedures. These specifications may prescribe a wide variety of occupational HVSA, but shall not be applied to firefighter turnout gear.
