This type of personal protective equipment (PPE) is worn to make the wearer easily seen in low-light or hazardous conditions.
Key features of this type of vest include:
Color: The vest in the image has two main colors, a fluorescent yellow top and a navy blue bottom. Fluorescent colors like yellow, orange, and red are used because they are highly conspicuous and stand out against most backgrounds.
Reflective Strips: The gray or silver strips on the vest are retroreflective tape. This material reflects light back to its source, making the person highly visible to drivers and machine operators at night or in poor weather.
Purpose: Safety vests are commonly used by workers in industries such as construction, road maintenance, and emergency services to prevent accidents.
