Hi Vis Clothing

High visibility clothing is made from conspicuous coloured materials and its primary use is to be noticed in low light and poor visibility conditions, predominantly around moving vehicles (cars, trucks and machinery- e.g. forklifts.)

The primary role of hi-vis clothing is to make the person stand out, so they are visible from all angles during poor lighting conditions or in a potentially hazardous situation. This ensures everyone is safe and visible to prevent accidents from occurring.

Upon the garment is stitched a reflective material which causes light to reflect from the wearer back to the light source, therefore allowing the wearer to be noticed in low light conditions which gives more time to react thus increasing safety within the workplace. The amount of reflective material on the garments will place it into one of the three class categories.

EN ISO 20471 is the standard that defines the minimum amount of reflective material a garment should have before it is deemed safe for the wearer’s needs. Increasing visibility during the day, in the twilight and the dark. Only orange and yellow garments conform to EN ISO 20471.

EN20471 classifies hi-vis garments into 3 categories, these classifications are 1, 2 or 3 where Class 1 provides the minimal level of visibility and class 3 provides the highest level.

Certification is based on the surface area of the fluorescent fabric and reflective tape.

Class 1 Class 2 Class 3
Reflective Tape 0.10 sqm 0.13 sqm 0.20 sqm
Fluorescent Material 0.14 sqm 0.50 sqm 0.80 sqm


It offers the lowest level of visibility and is suitable for low-risk situations where collisions and accidents are at a minimum. Typically, users will only have one item of hi-vis clothing on such as hi-vis trousers.


It offers better visibility and is recommended for heavy traffic areas such as class A B roadsteads. Like class 1, hi-vis waistcoats can be worn individually and will still comply with class 2 because the garment is worn at a more visible height.


It offers the highest level of visibility. This level of protection is required for high-risk areas such as motorways, airports or when working at night in the dark. Class 3 garments are typical hi-vis jackets or hi-vis coveralls.

Class 3 visibility can also be obtained if two hi-vis garments are worn together and are jointly certified i.e., Class 2 hi-vis waistcoat and Class 1 hi-vis trousers worn together could meet Class 3 as the total area of fluorescent and reflective material that encompasses the wearers body has now increased and therefore comply to Class 3.

Rail Industry Standard: RIS-3279-TOM

The construction and maintenance of railways warrant a different and more specific standard of high visibility clothing to be worn by workers. The high visibility clothing must be of satisfactory material, colour and reflectivity to be deemed suitable for any work being taken on railways.

RIS-3279-TOM determines that high visibility clothing is an essential item of personal protective equipment  (PPE), providing drivers of rail movements with a conspicuous warning of the presence of people within view on the lineside or on or near the line. Hi-Vis clothing equally benefits those managing the health and safety of workgroups, by improving the visibility of people when needing to account for them having moved to a place of safety.

According to RIS-3279-TOM high visibility clothing worn by people on the lineside or on or near the line should be orange in colour and within the colour range specified by EN ISO 20471 5.1.2. In addition, high visibility clothing should fully conform to EN ISO 20471.

RIS-3279-TOM also strongly advises the use of words or markings that help to quickly identify a company or an individual’s roles or to support emergency services if required; for example, heat-sealed company logos and titles such as “ROI” (Rail Incident Officer).
