The main risks
- thermal risks (cold, heat, wind, flame, metal projections …)
- risks related to poor visibility (building sites, roads…)
- chemical risks (dust, gas…)
- mechanical risks (cuts, shocks, tears, perforations…)
- biological risks (contamination by viruses, bacteria…)
- electric and electrostatic risks

Clothing will be selected according to its ability to protect against the risk encountered but also depending on its
comfort, its aestheticism, its functionality (adjustment methods, pockets, fastenings…)

General requirements
(This standard cannot be used alone but ony in association with a specific norm)

Protective clothing for use in welding and allied processes.


Protective clothing against
cold. Temperatures lower than -5°C

Protective clothing against foul weather
resistance to water penetration
class 1 to 3, class 1 is the lowest level
- resistance to water vapour resistance
class 1 to 3, class 1 is the lowest level

High visibility warning clothing for professional use
* Minimum area: 3 classes
The minimum surface of each visible material in m2 will determine the class of the garment

Minimum area in m2 Class 3 garments Class 2 garments Class 1 garments
0.80 0.50 0.14
Retroreflective material 0.20 0.13 0.10
Combined performance material     0.20

* Minimum values of retroreflexion (cd/(lx.m2) according to the entrance angle and observation angle: 2 classes.

en471The first figure (a) will indicate the category of the garment according to the necessary material
and the second number (b) will refer to the performance level of the retroreflective material (class 1 to 2).


   EN ISO20471 : 2013

High visibility clothing - Test methods and requirements
Risks associated with movements on the road and the presence of building site machinery and road vehicles are important regardless of the weather conditions, night or day.
EN ISO20471 is designed to facilitate the detection of people by wearing high visibility clothing which must be suitable and efficient .
Also, this standard specifies, among other things, the requirements of materials, color, retroflexion, minimum material surfaces, and their positions on protective clothing to achieve this purpose.
3 classes are defined according to the mandatory minimum visible surfaces in square meters.
Class 1 being the lowest and 3 the highest.
Classes of the retroreflective material of the old standard have been removed and the only remaining is the class 2.
To improve the detection of the carrier on all sides (360 °) , all parts of the product must contain fluorescent materials and reflective bands around the torso , legs for pants and sleeves for jackets (2 bands spaced by 50 mm ) .

Background fluorescent coloured material, for the day
Fluorescence is the ability of a material to reflect more light than it receives.
Consequently fluorescent colors seem more vivid than those which does not have this property.

Retroreflective material for night
A retro-reflector is a device capable of reflecting the light it receives back in directions close to the source Thus the driver
who light a pedestrian in the night with the headlights of his vehicle, can identifies very quickly the garment which features
a retroreflective material..

Protective clothing for industrial workers exposed to
heat (excluding firefighter’ and welders’ clothing).

en943EN943, EN14605, EN ISO13982, EN13034
Protective chlothing for use against chemicals
Type 1: gaz tight.
Type 2: non gaz tight.
Type 3: liquid tight.
Type 4: spray-tight
Type 5: protection to the full body against airborne solid particulates.
Type 6: limited protection against liquid chemicals.
