When it comes to workplace safety, high-visibility (hi-vis) clothing is essential for ensuring workers remain visible in hazardous environments. Whether you're on a construction site, directing traffic, or operating in low-light conditions, hi-vis safety apparel plays a vital role in accident prevention. However, not all hi-vis garments are the same. Understanding their key features and essential safety ratings is crucial when selecting the right apparel for your needs.
At Alex Direct, we stock a comprehensive range of hi-vis workwear, including vests, jackets, trousers, and coveralls, all compliant with UK safety standards. This guide will help you choose the best hi-vis clothing by explaining safety classifications, key features, and industry requirements.
Why Hi-Vis Safety Matters
Accidents often happen due to poor visibility, especially in industries where workers are exposed to moving vehicles, machinery, or low-light conditions. Hi-vis safety clothing increases visibility by using fluorescent materials and retroreflective strips that reflect light, making the wearer noticeable.
Industries that require hi-vis workwear include:
-
Construction sites
-
Roadside and traffic management
-
Warehouses and factories
-
Railway and airport workers
-
Emergency responders and security personnel
For official workplace safety guidance on protective clothing, refer to the HSE guide on protective clothing.

Essential Safety Ratings for Hi-Vis Workwear
In the UK, hi-vis clothing must comply with BS EN ISO 20471, which replaced the older EN 471 standard. Here’s what you need to know:
1. BS EN ISO 20471:2013 – The Industry Standard
This standard classifies hi-vis garments into three categories based on visibility level:
-
Class 1: Minimal visibility – Suitable for warehouse operatives and off-road workers.
-
Class 2: Moderate visibility – Recommended for roadside workers and construction site staff.
-
Class 3: Maximum visibility – Required for high-risk environments, such as highways or night shifts.
A Class 3 hi-vis jacket provides more reflective material than a Class 1 vest, making it the best choice for high-risk work environments.
2. RIS-3279-TOM – Railway Standard
For those working in the rail sector, hi-vis clothing must comply with RIS-3279-TOM, ensuring workers wear orange hi-vis clothing to contrast with the railway environment.
3. EN 343 – Waterproof and Breathability Ratings
Workers in outdoor environments need protection from rain and harsh weather conditions. EN 343-rated hi-vis jackets and trousers provide water resistance and breathability, ensuring comfort and durability.

4. EN 14116 – Flame-Retardant Properties
For jobs involving fire hazards, EN 14116-rated flame-retardant hi-vis clothing provides extra protection against heat and flames, making it ideal for electricians, welders, and offshore workers.
Key Features to Look for in Hi-Vis Clothing
1. Fluorescent Fabric for Daytime Visibility
Hi-vis garments are available in fluorescent yellow, orange, and red, which are the most visible colours in daylight.
2. Reflective Tape for Night Visibility
Retroreflective strips enhance visibility in low-light conditions, such as night shifts, tunnels, or poorly lit work areas.
3. Waterproof & Breathable Materials
For outdoor workers, EN 343-rated waterproof hi-vis jackets keep wearers dry and comfortable in wet conditions.
4. Multiple Pockets & Tool Holders
Practical hi-vis workwear includes secure pockets, tool loops, and pen holders, allowing workers to keep essential tools accessible.
5. Durability & Reinforced Stitching
Workwear should be hard-wearing, especially in physically demanding jobs. Look for triple-stitched seams, rip-stop fabrics, and reinforced knee panels.
6. Adjustable & Comfortable Fit
Features such as elasticated cuffs, adjustable waists, and breathable linings improve comfort and mobility, reducing worker fatigue.
