EN ISO 20471 - High Visibility
The EN ISO 20471 standard is an international standard that pertains to high-visibility clothing. This standard was developed to ensure the visibility and safety of workers operating in low-light conditions or near moving traffic, such as road workers, railroad employees, airport personnel, and emergency responders.
The EN ISO 20471 standard specifies the minimum requirements for high-visibility clothing intended to make the wearer visible under all lighting conditions, both during the day and at night. The standard covers both the materials used in high-visibility clothing and the design of the garments themselves.
To comply with the EN ISO 20471 standard, high-visibility clothing must meet various requirements, including:
- Fluorescent material colors: The clothing must be made of fluorescent material in one of the following colors: yellow, orange, or red. These colors are intended to make the wearer highly visible during the day.
- Retroreflective materials: The clothing must contain retroreflective materials that reflect light back toward the light source, such as vehicle headlights. This ensures that the wearer is visible at night.
- Contrast material: In some cases, the clothing may also include contrasting-colored material to further improve visibility.
- Design and placement of materials: The standard specifies the minimum area of fluorescent and retroreflective materials that must be used in the clothing, as well as the placement of these materials to ensure continuous visibility around the wearer.
The EN ISO 20471 standard classifies high-visibility clothing into three classes, based on the minimum area of visibility materials:
- Class 1: Offers the lowest level of visibility and is generally used for accessories such as safety vests or waistbands.
- Class 2: Offers a moderate level of visibility and is suitable for situations involving moderate risk. Examples include traffic vests or jackets.
- Class 3: Offers the highest level of visibility and is intended for high-risk situations, such as working along highways. This includes full high-visibility clothing sets, such as jackets and pants or coveralls.
It is important to note that the EN ISO 20471 standard is not the only standard that may apply to high-visibility clothing. Other standards, such as EN 343 (for protection against rain) or EN 11612 (for protection against heat and flames), may also be relevant, depending on the specific work environment and risks. When selecting high-visibility clothing, it is important to take into account all applicable standards and the specific needs of employees to ensure that the appropriate protection is provided.
In addition to the EN ISO 20471 standard, employers must also consider working conditions and the nature of the work to determine which class of high-visibility clothing is most suitable for their employees. Factors such as traffic speed, distance from traffic, lighting conditions, and the complexity of the background can all affect workers’ visibility and the required levels of protection.
In general, compliance with the EN ISO 20471 standard helps improve workers’ visibility in hazardous situations and reduce the risk of accidents and injuries. By providing the appropriate level of visibility, high-visibility clothing and accessories can play a crucial role in ensuring the safety of workers across a wide range of industries and work environments.
Rijkswaterstaat Regulations
Rijkswaterstaat, the implementing agency of the Dutch Ministry of Infrastructure and Water Management, is responsible for the management and maintenance of infrastructure in the Netherlands. To ensure the safety of workers on and around this infrastructure, Rijkswaterstaat sets specific requirements for the high-visibility clothing that must be worn by contractors and other parties involved.
According to Rijkswaterstaat’s regulations, workers operating in the immediate vicinity of roads, waterways, and other infrastructure projects must wear high-visibility clothing that complies with the EN ISO 20471 standard. Furthermore, Rijkswaterstaat typically requires workers to wear clothing that meets Class 3 of this standard, which offers the highest level of visibility. This ensures that workers operating in potentially hazardous situations—such as along highways or on construction sites—are clearly visible to passing traffic and other parties on-site.
In conclusion, Rijkswaterstaat (RWS) follows its own regulations (standard Class 3 for fabric and reflectivity, with orange for traffic workers and yellow for railroad workers).
