According to safety standards, firefighters must wear high-visibility safety vests that comply with which specification?

The requirement for firefighters to wear high-visibility safety vests is governed by ANSI 207, which specifies the design and performance requirements for high-visibility apparel used in emergency services. This standard focuses on ensuring that personnel are easily seen, particularly in environments where they may be exposed to vehicular traffic or other hazards.

The use of ANSI 207-compliant vests enhances the safety of firefighters by improving their visibility during operations, especially in low-light conditions or congested areas. The vest design includes reflective materials and bright colors to increase the likelihood that they will be noticed by drivers and other personnel, thereby reducing the risk of accidents.

In contrast, the other options relate to different standards. ANSI 101 is associated with protective clothing for general use, OSHA 1910 covers occupational safety and health standards but does not specifically address high-visibility apparel for emergency responders, and NFPA 1500 deals with fire department occupational safety and health programs but does not specifically set forth specifications for high-visibility garments.
