What is the standard for retroreflective vests?

The standard for retroreflective vests is primarily outlined in ANSI 207/107, which focuses on high-visibility safety apparel. This standard specifies the performance and design criteria for garments that provide visibility to workers who may be exposed to hazards from moving vehicles or equipment.

ANSI 207 emphasizes the need for retroreflective materials that enhance visibility in various light conditions, contributing to worker safety in environments where there is a risk of being struck by vehicles. The criteria set forth in this standard ensure that vests are made from materials that have specific brightness and retroreflectivity values, thereby allowing them to be effectively seen from a distance, especially in low-light or poor visibility conditions.

In contrast, the other options refer to different categories of protective gear or standards. NFPA 1975 relates to station/work uniforms for fire protection personnel, OSHA 1910.145 covers safety signage and various related requirements, and ISO 20471 addresses high-visibility clothing but in a broader international context. Therefore, ANSI 207/107 is the most relevant standard for retroreflective vests specifically used in safety applications, particularly for environments where high visibility is critical.
