Understanding UK Hi Vis Regulations for Workplace Safety

Hi-Vis can be a very complicated topic, so let's have a look at the UK Hi-Vis Regulations.

High-visibility clothing (hi-vis) is a vital safety gear in numerous industries where stringent regulations ensure worker safety. Understanding the regulations and standards surrounding hi-vis clothing is crucial for both employers and employees. 

In this article, we'll delve into the various hi-vis regulations in the UK, including those set by EN ISO 20471, the maintenance of compliance, differences from previous regulations like EN471, the classification of hi-vis garments, and how branding affects hi-vis compliance.

What are the UK’s Hi Vis Regulations?

In the UK, high-visibility clothing is governed by a set of regulations to ensure the safety of workers, particularly those in high-risk environments such as construction sites, roadworks, and railway industries. These regulations mandate the use of hi-vis clothing to improve visibility and reduce the risk of accidents.

One of the primary regulations governing hi-vis clothing in the UK is EN ISO 20471, which sets the standards and test methods for high-visibility clothing. This standard ensures that hi-vis clothing provides optimal conspicuity in situations where the risk of not being seen is high. Additionally, the Railway Industry Standard RIS-3279-TOM also applies to hi-vis clothing used in the railway industry, providing specific requirements tailored to this sector.

Understanding and complying with these regulations is vital for both employers and employees to ensure workplace safety and regulatory compliance.

Understanding EN ISO 20471

EN ISO 20471 is the key standard governing high-visibility clothing in the UK. It specifies the requirements and test methods for high-visibility clothing to ensure wearers are easily visible in hazardous situations. This standard is crucial for industries where worker safety depends on being seen, such as construction, road work, and emergency services.

The standard defines high-visibility clothing as "warning clothing intended to provide improved conspicuity in situations where the risk of not being seen is high.” This definition underscores the critical role of hi-vis clothing in enhancing the visibility of workers, especially in low-light conditions or near-moving vehicles. High-visibility clothing must be highly noticeable against any background, in both daylight and in the illumination provided by vehicle headlights.

EN ISO 20471 outlines various requirements that hi-vis clothing must meet, including specifications for fluorescent fabric colour, minimum areas of reflective material, and placement of reflective tape. 

EN ISO 20471 outlines various requirements that hi-vis clothing must meet, including specifications for fluorescent fabric colour, minimum areas of reflective material, and placement of reflective tape. Fluorescent materials are designed to make the garment visible during the day, while retroreflective materials ensure visibility at night by reflecting light back towards its source, such as car headlights.

The standard also includes guidelines for the design of high-visibility clothing to ensure maximum visibility. This includes the placement of reflective strips to outline the human form and enhance recognition, as well as ensuring that the high-visibility areas are not obstructed by accessories or equipment. Furthermore, the durability of the materials is tested to ensure they maintain their visibility properties after repeated wear and washing.

What are the Different Classes of Hi-Vis?

High-visibility clothing is categorised into three classes under the EN ISO 20471 standard, each providing different levels of visibility based on the amount of fluorescent and reflective material used. Understanding these classes helps ensure that workers are appropriately protected in varying environments.

EN ISO 20471 Class 1

Class 1 is the lowest level of protection. Clothing in this class is typically used in environments with minimal risk. They must have a minimum amount of high-visibility material, including at least 0.14 square metres of fluorescent fabric and 0.10 square metres of reflective material. These garments are suitable for situations where slow-moving vehicles are present, and there is a lower risk of not being seen.

EN ISO 20471 Class 2

Class 2 provides an intermediate level of protection and is often used in environments with a moderate level of risk. These garments require at least 0.50 square metres of fluorescent fabric and 0.13 square metres of reflective material. Class 2 clothing is appropriate for workers who are exposed to traffic speeds up to 50 mph, making it suitable for road maintenance crews and delivery drivers.

EN ISO 20471 Class 3

Class 3 offers the highest level of visibility and is used in the most hazardous environments. These garments must include a minimum of 0.80 square metres of fluorescent material and 0.20 square metres of reflective material. Class 3 clothing is designed for workers who face high-risk situations, such as those working on motorways, railways or in emergency response roles, where the risk of not being seen is highest.

Maintaining Compliance with Hi-Vis Regulations

Ensuring that high-visibility clothing remains compliant with regulations is crucial for workplace safety. Here's how you can maintain compliance with hi-vis regulations:

• Proper Care and Maintenance: Hi-vis clothing should be cared for according to manufacturer instructions. This includes washing instructions and limitations on the number of washes. Typically, hi-vis clothing has a limited number of washes before its effectiveness diminishes - usually with 25 washes being the maximum. It's essential to replace hi-vis garments after reaching this limit to ensure continued visibility.
• Regular Inspections: Employers should conduct regular inspections of hi-vis clothing to check for signs of wear, damage, or fading. Any garments that no longer meet the required standards should be replaced promptly to maintain worker safety.
• Choosing Durable Options: When selecting hi-vis clothing, opt for durable options that offer long-lasting visibility. Look for garments with features designed to withstand frequent washing and extended use without compromising visibility.

Differences from Previous Regulations (EN471)

While both standards aim to improve worker visibility in hazardous conditions, EN ISO 20471 introduces several key updates and enhancements over EN471.

• International Standards: One of the primary differences is that EN ISO 20471 is an international standard, harmonised with ISO standards, ensuring greater consistency in high-visibility clothing regulations across different countries. This harmonisation helps multinational companies maintain uniform safety practices and simplifies compliance for businesses operating in various regions.
• Defined Body Sections: EN ISO 20471 defines specific body sections to simplify compliance assessment. These sections include the torso, arms, and legs, and garments must meet minimum visibility requirements for each designated area. This approach offers a clearer understanding of compliance standards for both manufacturers and wearers.
• Enhanced Class 3 Requirements: Class 3 hi-vis garments under EN ISO 20471 have stricter requirements compared to EN471. For example, the fluorescent fabric must cover either the torso and arms or the torso and legs, with reflective bands on permanent display. Any obstruction to the reflective bands, such as sleeves, necessitates additional reflective bands to maintain compliance.
• Updated Performance Standards: EN ISO 20471 includes updated performance standards for both fluorescent fabric and reflective tapes. While the colour fastness of fluorescent fabric has been upgraded, requirements for tensile, burst, and tear strength have been adjusted to reduce snagging risks. Similarly, reflective tapes must meet stringent durability standards to ensure long-term effectiveness.

How Branding Affects Hi-Visibility Clothing

Branding plays a significant role in the customisation of hi-vis clothing for businesses and organisations. However, it's essential to consider how branding impacts the compliance and effectiveness of hi-vis garments.

When adding logos or branding to hi-vis clothing, it's crucial to ensure that the branding does not compromise the visibility or compliance of the garment. Here's how branding can affect hi-vis compliance:

• Minimum Surface Area Requirements: Hi-vis standards specify minimum surface area requirements for fluorescent materials to ensure adequate visibility. When adding logos or branding, it's essential to ensure that the branding does not reduce the visibility of the fluorescent background material below the required minimum.
• Placement of Branding: The placement of logos and branding on hi-vis garments is critical. Logos should be strategically positioned to maintain the required surface area of fluorescent material visible from all angles. Placing logos in high-visibility areas, such as the front and back of the garment, can help maintain compliance.
