Personal protective equipment - Knee protectors for work in the kneeling position – Part 3: Requirements for the combination of knee pads and garments (type 2)

This part of EN 14404 specifies the requirements for individual knee pads combined with garments (type 2) for use by work in kneeling position.

Persönliche Schutzausrüstung - Knieschutz für Arbeiten in kniender Haltung - Teil 3: Anforderungen an die Kombination von Kniepolstern und Bekleidung (Typ 2)

Dieses Dokument legt die Anforderungen an einzelne Kniepolster in Kombination mit Bekleidung (Typ 2) für Arbeiten in kniender Haltung fest.
WICHTIG — Als Kombination aus Bekleidung und Polster unterliegen diese Formen des Knieschutzes somit einer gemeinsamen Untersuchungspflicht.
Eine besondere Kombination von Bekleidung und Polstern, die auf Interoperabilität basieren, ist in prEN 14404-4 beschrieben und sind von diesem Teil ausgeschlossen.
Die Position von Knieschutz des Typs 2 in oder an der Hose kann fest oder justierbar sein. Die Polster bestehen aus Schaumstoff oder anderen Materialien, die in Knietaschen der Bekleidung angeordnet oder dauerhaft in oder an der Bekleidung befestigt sind.

Équipements de protection individuelle - Protection des genoux pour le travail à genoux - Partie 3 : Exigences relatives à la combinaison de genouillères et de vêtements (type 2)

Le présent document spécifie les exigences relatives aux plaques de genouillères individuelles associées à des vêtements (type 2) utilisées pour le travail à genoux.
IMPORTANT - En tant que combinaison de vêtement et de plaque de genouillère, ces formes de protections des genoux sont donc soumises à une obligation d’examen conjoint.
Une combinaison spécifique de vêtement et de plaque de genouillère fondée sur l’interopérabilité est décrite dans le prEN 14404-4 et est exclue de la présente partie.
La position des protections des genoux de type 2 dans ou sur les pantalons peut être fixe ou réglable. Les plaques de genouillères sont constituées de mousse de plastique ou d’autres matériaux positionnés dans les poches de genoux des vêtements ou fixés de façon permanente dans ou sur les vêtements.

European foreword

This document (prEN 14404-3:2019) has been prepared by Technical Committee CEN/TC 162

“Protective clothing including hand and arm protection and life jackets”, the secretariat of which is held

by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 14404:2004+A1:2010.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this

document.

This standard “Personal protective equipment - Knee protectors for work in the kneeling position” is

split into 6 parts:
— Part 1: Test methods
— Part 2: Requirements for wearable knee protectors (type 1)
— Part 3: Requirements for the combination of knee pads and garments (type 2)

— Part 4: Requirements for the combination of interoperable knee pads and garments (type 2)

— Part 5: Requirements for knee mats (type 3)
— Part 6: Requirements for kneeling systems (type 4)

Introduction

Kneeling is a frequently occurring working position, but one which is problematic from an occupational

health viewpoint. Without knee protectors, workers may suffer immediate injuries from hard surfaces

and small stones and similar objects lying on the surfaces. However, no knee protector can ensure that

workers will not suffer medical complications if they are required to kneel for long periods.

It is important that knee protectors do not compromise venous drainage in the leg while kneeling or

standing up. Therefore, it is important that it is easy for workers to change position and to stand up to

re-establish a normal blood circulation at frequent intervals while wearing knee protectors.

Work in a kneeling position involves the risk of chronic diseases such as prepatellar bursitis and

cartilage injuries caused by continuous pressure on the knees. Knee protection is therefore

recommended for all work in the kneeling position. The protection should distribute forces evenly and

prevent small hard objects on the ground causing injuries. Many workers have pre-existing damage to

their knees, particularly to their cartilages from sports injuries and from previous work. These injuries

will be made worse by further kneeling. Wearing knee protectors cannot correct existing damage, but

should slow down further damaging effects.

Work in a kneeling position may expose the skin of the shins, knees and thighs to toxic and corrosive

materials normally kept off the body while walking and standing by waterproof or water-resistant

footwear. Knee protectors and trousers for use with such wet materials and particularly wet cement,

should take this into account and provide adequate protection, as does footwear.
For working in kneeling position exist 4 types of knee protectors:
— wearable knee protectors (type 1),
— knee pads in combination with garments (type 2),
— knee mats (type 3) and
— kneeling systems (type 4)

This document describes test methods, specifies requirements for knee protectors and defines

performance levels. Requirements for the marking of knee protectors and the information to be

supplied by the manufacturer are given. Where protection against additional hazards is claimed,

performance requirements from other applicable standards may also be applied.

This document does not apply to knee protectors that are medical devices or are intended for sports

and motorcycles.

It should be reminded that the EU regulation requires an examination on combined products when

protective insert is included. But it should be mentioned that the product diffusion on the market can be

based on different retailing circuits, providing that the marking mentions to use the combination to get

the full foreseen protection.

1 Scope

This document specifies the requirements for individual knee pads combined with garments (type 2)

for use by work in kneeling position.

IMPORTANT - As a combination of garment and pad, these forms of knee protection are thus

subject to a joint examination obligation.

A specific combination of garment and pad based on interoperability is described in prEN 14404-4 and

are excluded of this part.

The position of type 2 knee protectors in or on trousers can be fixed or adjustable. The pads consist of

foam plastic or other materials that are positioned in knee pockets of the garments or permanently

fastened in or on the garments.
