In professions where visibility is paramount, adherence to international safety standards is crucial to ensuring the effectiveness of hi-vis polos. This overview provides essential information on key compliance standards and regulations that hi-vis polos should meet, guaranteeing that workers are equipped with attire that not only enhances visibility but also complies with global safety benchmarks.

EN ISO 20471:2013 (European Standard):

The European Standard EN ISO 20471 outlines the specifications for high-visibility clothing. hivis polo conforming to this standard must meet specific criteria regarding color, retroreflection, and minimum visible areas. Class 2 and Class 3 classifications are assigned based on the amount of fluorescent and retroreflective material used, with Class 3 offering the highest level of visibility.

ANSI/ISEA 107-2020 (United States):

The American National Standard for High-Visibility Safety Apparel and Headwear, ANSI/ISEA 107-2020, sets guidelines for hi-vis apparel in the United States. It categorizes garments into three types (Type O, Type R, and Type P) based on intended use, and classifies them into three visibility levels (Class 1, Class 2, and Class 3) depending on the amount of visible materials.

AS/NZS 4602.1:2011 (Australia and New Zealand):

In the Asia-Pacific region, Australia and New Zealand adhere to the AS/NZS 4602.1:2011 standard for high-visibility safety garments. This standard specifies the color and luminance requirements for fluorescent materials, as well as the minimum area and arrangement of retroreflective materials. It classifies garments into different classes based on the amount of visible material used.

Key Elements in Compliance:

  1. Color Requirements:

Compliance standards specify the fluorescent background color for hi-vis polos, typically in shades of yellow, orange, or red. The color is chosen to maximize visibility in various lighting conditions.

  1. Retroreflective Material:

Hi-vis polos must incorporate retroreflective material to enhance visibility during low-light situations. The placement and quantity of retroreflective material depend on the specific class and type of garment.

  1. Design Specifications:

Compliance standards define the minimum visible areas and placement of fluorescent and retroreflective materials on hi-vis polos. The design is crucial to ensure that workers remain visible from different angles.

  1. Classifications:

Garments are classified into different types and classes based on their intended use and the amount of visible material present. This classification aids employers in selecting the appropriate hi-vis polo for specific job roles and environments.


Adhering to international safety standards is paramount in the design and manufacturing of hivis polo. Whether it’s the European Standard, the American National Standard, the Australian/New Zealand Standard, or the global ISO standard, compliance ensures that workers are equipped with high-visibility apparel that meets stringent criteria for visibility, durability, and overall safety. Employers and workers alike benefit from the assurance that the hi-vis polos worn on the job adhere to established global benchmarks, contributing to a safer and more secure work environment.
