What is one requirement for traffic vests to ensure ANSI compliance?

For traffic vests to ensure compliance with ANSI (American National Standards Institute) regulations, they need to be break-away. This requirement is critical for safety, particularly in high-risk environments where emergency responders may be exposed to moving vehicles. Break-away vests are designed to tear away from the body with a certain level of force, thereby preventing entanglement that could lead to serious injury if a responder is accidentally struck or caught on a moving vehicle or equipment. This feature enhances the safety of the individual wearing the vest, allowing them to focus on their duties with a reduced risk of injury.

While reflective strips, fluorescent colors, and adjustable sizing are also important aspects of traffic safety vests, they are not the specific requirement that directly relates to ANSI compliance in terms of minimizing risks associated with the actions of emergency responders in hazardous situations.
