What is Safety Clothing?
Safety clothing is a category of personal protective equipment designed to protect workers from specific on-site hazards. High-visibility clothing improves worker visibility in environments where moving vehicles, plant, or low light conditions create risk of collision. Wet weather clothing protects against the effects of prolonged exposure to rain, wind, and cold, which in outdoor site environments present genuine health and safety risks.
Unlike standard workwear, safety clothing is specifically engineered to meet recognised safety standards. High-visibility garments are certified to EN ISO 20471, which sets minimum requirements for the area of fluorescent and retroreflective material depending on risk level. When clothing is designed to protect against safety risks rather than simply provide durability or comfort, it is classified as PPE under the PPE at Work Regulations 1992.
Hi-Vis Clothing by Garment Type
Our range covers every hi-vis and wet weather garment type required on UK construction, rail, highways, and industrial sites.
Choosing the Right Hi-Vis and Safety Clothing
The correct safety clothing depends on the visibility risk and weather conditions present in the working environment. High-visibility garments are required wherever workers are exposed to moving vehicles, plant, or low light conditions. The class of garment needed depends on the level of risk: Class 2 is sufficient for most construction and industrial environments, while Class 3 is required for higher-risk locations such as highways and rail trackside work.
Wet weather clothing protects against the productivity and health impacts of prolonged outdoor exposure, and many wet weather garments also carry EN ISO 20471 certification, combining weatherproofing with visibility compliance in a single garment. Selecting the right garment type and class ensures workers remain protected, visible, and compliant across all site conditions.
| Environment / risk | Garment required | Standard / class |
|---|---|---|
| Construction site, general | Hi-vis vest, jacket or polo shirt | EN ISO 20471 Class 2 |
| Highways and road working | Hi-vis jacket and trousers (full outfit) | EN ISO 20471 Class 3 |
| Rail trackside / lineside | Orange hi-vis jacket and trousers | EN ISO 20471 Class 3 · RIS-3279-TOM |
| Outdoor work in rain and wind | Hi-vis waterproof jacket and trousers | EN ISO 20471 · Waterproof rated |
| Cold weather site working | Hi-vis bodywarmer or insulated jacket | EN ISO 20471 · Insulated fill |
| Warm weather / indoor site use | Hi-vis polo shirt or T-shirt | EN ISO 20471 Class 2 |
Hi-Vis and Safety Clothing Supply for Construction, Rail and Industry
Hi-vis clothing is a legal requirement across construction, highways, rail, and industrial sites where workers are exposed to moving vehicles or plant. Selecting the correct EN ISO 20471 class for the environment ensures compliance and reduces the risk of incidents in high-traffic areas. From vests and polo shirts for general site use to Class 3 jackets and trousers for highways and rail trackside working, the right garment depends on the level of risk present.
At CMT Group, we support contractors, procurement teams, and site managers with scalable hi-vis and safety clothing solutions built for performance and consistency. Our range covers every garment type required on UK construction, rail, highways, and industrial sites, with bulk pricing and account management available for teams requiring ongoing supply.
Frequently asked questions
What is safety clothing?
Safety clothing is protective workwear designed to reduce worker exposure to hazards such as low visibility, weather conditions, heat, chemicals, and physical risks. Unlike standard workwear, safety clothing is engineered to meet recognised safety standards and provide measurable protection in hazardous environments.
Is safety clothing classed as PPE?
Yes. When clothing is specifically designed to protect against safety risks, it is classified as personal protective equipment (PPE) under UK regulations. Garments such as high-visibility clothing, flame-retardant clothing, and chemical-protective coveralls all fall within the scope of the PPE at Work Regulations 1992.
What safety clothing is required on construction sites?
Common requirements include high-visibility clothing (Class 2 or Class 3, EN ISO 20471) for work near moving vehicles, waterproof outerwear for prolonged outdoor exposure, and flame-retardant garments for work near heat or ignition sources. Specific requirements depend on the site risk assessment.
How do I choose the right safety clothing?
Safety clothing should be selected to match the specific hazards present in the working environment. High-visibility garments are needed where visibility is a risk, FR clothing where heat or flame is present, and waterproof outerwear for prolonged outdoor exposure. Each garment should meet the relevant EN standard for its hazard category.
Why buy safety clothing from CMT Group?
CMT Group supplies trade-quality safety clothing at scale, with fast UK delivery including same-day and next-day despatch for urgent site requirements. Our range covers every safety clothing category required on UK construction, rail, and industrial sites, with bulk pricing and account management available for procurement teams.
EN ISO 20471 Class 2 vs Class 3 Hi-Vis: Which Do You Need?
EN ISO 20471 Class 2 and Class 3 differ primarily in the total minimum area of fluorescent background material and retroreflective banding required. Class 2 sets a lower threshold and is appropriate for most construction sites, infrastructure work, and industrial environments where workers may encounter slow-moving vehicles or plant machinery. Class 3 requires a significantly greater total area of fluorescent and retroreflective material, making the wearer visible at greater distance and in more demanding conditions.
Class 3 is mandatory for higher-risk environments including highway maintenance, road working, and all rail trackside work. A single Class 3 garment — typically a jacket — achieves the required material areas on its own, while a Class 2 jacket combined with certified hi-vis trousers can also achieve Class 3 equivalent coverage. The correct class for any site should always be determined through a formal risk assessment.
