Vietnamese Regulations and Usage Contexts:

In Vietnam, safety vests are part of PPE (Thiết bị bảo hộ cá nhân) and are especially important in:
- Construction Sites (Công trường xây dựng)
- Traffic & Road Work (Công trình giao thông)
- Factories and Warehouses (Nhà máy, kho bãi)
- Event Security or Outdoor Staff (Bảo vệ, nhân viên ngoài trời)
Vests are categorized similarly to international standards (like ANSI/ISEA Class 1, 2, 3), with higher classes required for high-risk environments such as highway construction or nighttime operations.
And more translation English to Vietnamese
Personal Protective Equipment (PPE) refers to all gear worn by workers to protect themselves. This includes helmets, gloves, boots, and reflective vests. In Vietnamese, PPE is called "Trang bị bảo hộ cá nhân".
Reflective Tape or Strips are bright strips attached to the vest. They shine when light hits them, making the person wearing the vest easier to see at night or in dark areas. In Vietnamese: "Dải phản quang".
Fluorescent Colors are bright colors such as neon orange, yellow-green, or bright lime. These help the vest stand out during the daytime. In Vietnamese: "Màu huỳnh quang".
Visibility refers to how easily other people can see the person wearing the vest. High visibility is important in places like construction zones, roads, or factories. In Vietnamese: "Tầm nhìn" or "Độ dễ nhìn thấy".
ANSI/ISEA Standards are American safety standards that set requirements for the brightness and reflectiveness of safety vests. These standards are especially used in international projects. In Vietnamese: "Tiêu chuẩn ANSI/ISEA".
Day/Night Visibility means the vest can be seen both during the day (thanks to the fluorescent color) and at night (thanks to reflective materials). In Vietnamese: "Nhìn thấy rõ cả ngày và đêm".
Class 1, Class 2, and Class 3 Vests represent different levels of visibility protection. Class 1 is for low-risk work, Class 2 is for medium-risk environments like roadwork or general construction, and Class 3 offers the highest visibility, used in high-risk environments like highways or near fast-moving traffic. In Vietnamese: "Áo phản quang cấp 1, 2, 3".
High-Risk Environments are locations where accidents can happen easily, such as roads, large construction sites, or areas with moving machinery. Reflective vests are required in these areas. In Vietnamese: "Môi trường nguy hiểm".
Retroreflective Material refers to the special material on the vest that reflects light back to its original source, like headlights. This makes the vest shine brightly at night. In Vietnamese: "Vật liệu phản quang ngược".
Incident Prevention is the main purpose of wearing reflective vests and other PPE. The goal is to reduce accidents by increasing the visibility of workers in dangerous environments. In Vietnamese: "Phòng tránh tai nạn".
