Radians SV24-3 Type R Class 3 Surveyor Safety Vest has a 5 point breakaway system at shoulders, sleeve, sides and front Zip-N-Rip™ zipper closure that break away when tugged with moderate force. Excellent choice for extreme traffic hazards around moving machinery or equipment to prevent pulling workers into hazards. Class 3 safety vests are designed to protect the worker with maximum visibility. These vests are designed with the most hi-vis material coverage and reflective stripes for workers exposed to complex work environments. Class 3 vests are required in environments with high-speed traffic, high-risk environments and where the worker must be visible through a full range of motions at a minimum of 1280 feet (390 meters).
