High visibility

Wearing high visibility clothing prevents accidents and injuries in the workplace by ensuring that your company’s workers are clearly visible

Accidents in the workplace, although decreasing year on year, are very common and often associated with the absence of safety equipment and high visibility.

The EN ISO 20471 standard for high‐visibility professional clothing replaced the EN 471:2003 standard in 2013. Both standards specify the characteristics that a high‐visibility garment should have in order to visually signal the presence of the user in all light conditions, both day and night. However, while the previous standard focused essentially on the type of garment, the current standard attaches greater importance to the area of the body that is covered by the high‐visibility garment, namely, a) the torso only; b) torso and arms; c)legs; d) torso and legs; e)torso, arms and legs. In view of these changes, if you are responsible for your company’s high‐visibility professional clothing, make sure it complies with the current standard. Since 2013, all high‐visibility items that comply with the respective standard must be marked with CE signs.

High-visibility clothing consists mainly of three components:

  • Fluorescent elements made with special pigments that are brighter than normal colours. Fluorescent colours make the most of any existing sunlight and may be more visible in low light
    conditions, such as dusk or on cloudier days. This type of clothing also provides a strong contrast against most backgrounds/environments.

  • Reflective tapes to increase visibility in the dark as they do not provide much contrast during daylight.

  • Contrast material designed in a darker fabric to highlight fluorescent elements and reflective tapes and strategically placed in places most prone to dust and dirt accumulation (cuffs, knees and trouser bottoms).

The current standard allows the use of 3 colours for the background material and combined effect, namely fluorescent yellow, fluorescent orange and fluorescent red.

High-visibility professional clothing is distributed on a scale of 1 to 3:

Class 1: lower degree of visibility (e.g. harness straps or high visibility trousers only)

Class 2: intermediate degree of visibility (e.g. waistcoats or capes)

Class 3: higher degree of visibility (e.g. long‐sleeved jackets or ensembles covering a large body area).

Taking into account the update of the standard, a higher class than the classification of an article can be achieved when grouping parts that may be of a lower class but cover an extended body area corresponding to the minimum requirements of a higher class. However, this higher class must be specified in the instructions for use and on the labelling of both garments.

Table 1 – Minimum required areas of visible material in m2.

Material Clothing Class 3 Clothing Class 2 Clothing Class 1
Background material 0,80 0,50 0,14
Retroreflective material 0,20 0,13 0,10
Combined effect material not applicable not applicable 0,20

Note: The garment class is determined by the smallest area of visible material.

This labelling corresponds to a high visibility garment of class 2 (number on the right).

Applications:

Workers in the gas and electricity industry and in the transport industry such as road, rail and airports. Construction workers, first responders and street and public cleaning workers also benefit from this increased visibility.
