IMPROVED VISIBILITY EQUIPMENT FOR MEDIUM RISK SITUATIONS

This standard specifies the requirements for enhanced visibility equipment in the form of a garment, or device, capable of visually signalling the presence of the user.

Enhanced Visibility Equipment is intended to provide visibility of the wearer in low or medium risk situations in all daylight conditions and/or under the illumination of vehicle headlights or headlights in the dark. This standard does not apply to high visibility equipment in high risk situations which are covered by EN ISO 20471.

Minimum surface in m² for B1 and B2 type:

Minimum surface in m² for type A, B3 and AB type:

This standard specifies the requirements and test methods for non ventilated protective clothing against radioactive contamination in the form of particles.

Clothing of this type is designed only to protect the body, the arms and the legs of the wearer, but it may be used with accessories that protect other parts of the wearer’s body (for example, boots, gloves, respiratory protective device - APR).

The garments are classified according to their nominal protection factor (ratio between the concentration of test particles in the ambient atmosphere and the concentration of test particles inside the garment), determined in relation to the total inward leakage (ratio between the concentrations of test particles insider the garment and inside the test chamber).

The classes are as follows:

PROTECTION USED IN WELDING AND ALLIED PROCESSES

This standard specifies the performance requirements for protective clothing for use by operators in welding and allied processes with comparable risks. This type of protective clothing is intended to protect the wearer against molten metal splash, short contact with flame and UV radiation. It is intended to be worn at ambient temperature, continuously for up to 8 hours.

HIGH VISIBILITY CLOTHING

This standard specifies the requirements for protective clothing aiming to signal the presence of the wearer visually, so that he may be detected and seen in hazardous situations, in all conditions of daylight, and night under illumination of car headlights.

There are three classes of high-visibility clothing. Each class must have minimum surfaces of visible material constituting the garment; the higher the class, the more visible the garment:

Marking : 

X : Class of high visibility surface (from 1 to 3)

EN ISO 20471  

2
Max. 25x

EN ISO 20471

2 : Class of hight visibility surface (from 1 to 3)

Max. 25x : Optional marking, number of maximum washes authorized for the model. On this example: 25 washes maximum (see indication of service temperature on the garment tag).

This standard specifies the requirements and performance test methods for protective clothing against cold at temperatures lower than -5°C (cold store / extreme cold workers).

There are two types of garment :

Garments: covering part of the body, e.g. parka, jacket, coat.

Suits: covering the whole body (trunk + legs), e.g. coveralls, parka & dungarees.

X (undergarment B/C/R) : /cler of the garment

X : Class of air permeability, AP

X : Class of resistance to water penetration WP (Optional)

EN ISO 374-5 specifies the requirements and test methods for protective gloves intended to protect the user against microorganisms (mold and bacteria, potentially viruses).

Penetration of molds and bacteria (tested according to EN374-2): Test by which the water and airtightness of a glove is checked.

Penetration of viruses (tested according to method B of ISO 16604): Process that determines the resistance to penetration by blood-borne pathogens.

- Test method using Phi-X174 bacteriophage.

The glove, depending on its type, will bear the following pictogram:

Examples of application:

The field of use is decisive because, depending on the case, the glove may have to combine several properties in order to meet the necessary protection requirements. It is therefore very important to refer to the recommended areas of use and the results of the laboratory tests found in the instructions for use. However, it is recommended to check that the gloves are suitable for the intended purpose by carrying out tests beforehand, because the conditions at the workplace may differ from those of the standard test, depending on the temperature, abrasion and degradation.

Standard ISO 18889 specifies the performance requirements of protective gloves for pesticide operators and re-entry workers.

G1 gloves are suitable when the potential risk is relatively low. These gloves are not suitable for use with concentrated pesticide formulations and/or for scenarios where mechanical risks exist. G1 gloves are typically single use gloves.

G2 gloves are suitable when the potential risk is higher. These gloves are suitable for use with diluted as well as concentrated pesticides. G2 gloves also meet the minimum mechanical resistance requirements and are therefore suitable for activities that require gloves with minimum mechanical strength.

GR gloves provide protection only to the palm-side of the hand for a re-entry worker who is in contact with dry and partially dry pesticide residues that remain on the plant surface after pesticide application.

Standard EN ISO374-1, protective gloves against chemicals and micro-organisms, specifies the performance requirements required for gloves for protecting users against chemical products and/ or micro organisms and defines the terms to be used:

• Penetration (tested as per standard EN374-2): Diffusion of water or air, to check the impermeability, on a non-molecular level, of a chemical product and/or micro-organism through the porosities, seams, micro-holes or other imperfections present in the material of the protective glove.

• Degradation (tested as per standard EN374-4): Determination of the physical resistance of materials to degradation after continuous contact with hazardous chemicals.

• Permeation (tested as per standard EN374-3 or EN16523): Process by which a chemical product diffuses through the material of a protective glove, by continuous contact, on a molecular level. The EN ISO version of standard 374-1, introduces the concept of three types of protection against the permeation of chemicals:

- Type A: The glove gives a performance index to permeation at least equal to 2 for 6 chemical test substances taken from the list of chemicals specified in the standard.

- Type B : The glove gives a performance index to permeation at least equal to 2 for 3 chemical test substances taken from the list of chemicals specified in the standard.

- Type C : The glove gives a performance index to permeation at least equal to 1 for 1 chemical test substances taken from the list of chemicals specified in the standard.

The EN511 standard defines the requirements and test methods for cold protection gloves from cold transmitted by convection or conduction down to -30°C (optionally up to -50°C). This cold can be from climatic conditions or industrial activity.

The selection process of a cold protection glove must take into account several parameters such as the ambient temperature, the health of the person, the duration of exposure, and the level of activities...

Standard EN16350 provides additional requirements for protective gloves that are worn in areas where flammable or explosive areas exist or might be present.

Further electrostatic properties can be determined through EN1149-1 (surface electrostatic properties) or EN1149-3 (charge decay), but cannot be used for electrostatic dissipative protective gloves.

The EN407 standard specifies the test methods, the general requirements, the thermal performance and the labelling of gloves and cuffs to protect from heat and fire. It applies to all gloves which must protect hands from heat and/or flames in any one or several of the following forms: fire, contact heat, convective heat, radiating heat, small spray of molten metal or large spray of melting metal.

If the product claims flammability resistance, the pictogram will be                                           

If the product does not claim any resistance to flammability (0 or X), the pictogram will be      

The reference standard, cannot be used alone, but only in combination with another standard containing protection performance requirements.

• Conform to harmlessness (pH, chrome VI levels, etc…).

• Conform to the size charts (see chart on below).

• Assess the dexterity, breathability, and comfort.

• Conform to the labelling, information and identification instructions.
