A reflective safety vest is a crucial piece of Personal Protective Equipment (PPE) designed to make the wearer highly visible, reducing the risk of accidents in hazardous environments, especially those involving moving vehicles or equipment.

Their effectiveness comes from two main components:

1. Fluorescent Background Material: Provides high visibility during daylight hours.

2. Retroreflective Material (Strips/Tape): Reflects light directly back to its source (like car headlights), ensuring visibility in low-light or nighttime conditions.
