What is EN ISO 20471:2019?

The EN ISO 20471:2019 standard pertains to high visibility clothing, ensuring the safety of workers in hazardous environments. Adopted by the European Union and International Organization for Standardization (ISO), it establishes guidelines for the design, performance, and materials used in high visibility garments.

Classification of High Visibility Clothing

EN ISO 20471 classifies high visibility clothing into three categories – Class 1, Class 2, and Class 3. Each class represents different levels of conspicuity, with Class 3 offering the highest visibility.

Class 1 garments are suitable for low-risk work environments where there is ample separation between vehicles and pedestrians. Class 2 garments are intended for intermediate risk situations where increased visibility is necessary. Class 3 garments are specifically designed for high-risk environments, providing the highest level of visibility to ensure the safety of workers.

Requirements and Testing Criteria

To comply with the EN ISO 20471 standard, high visibility clothing must meet specific requirements in terms of fluorescent color, retroreflective tape configuration, and minimum visible surface area. The standard also outlines testing methods to evaluate the durability and performance of the garments. These tests include measurements of retroreflection, colorfastness, tear strength, and more.

Benefits of EN ISO 20471

The implementation of EN ISO 20471 ensures that workers in high-risk situations are provided with appropriate personal protective equipment. By wearing high visibility clothing that meets the standard, workers become more visible to others, reducing the risk of accidents and improving their overall safety. It also increases the visibility of workers during daytime and nighttime hours, regardless of weather conditions.

In addition to enhancing worker safety, EN ISO 20471 compliance also helps businesses meet legal requirements and regulations related to worker protection. Its adoption promotes a culture of safety in the workplace and demonstrates a commitment from employers to prioritize employee well-being.
