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).

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.

Four performance levels are defined. The tests for the performance levels are described in 4 of

prEN 14404-1:2019:

— level 0: knee protectors suitable for use on flat floor surfaces and providing no protection against

penetration.

— level 1: knee protectors suitable for use on flat floor surfaces and providing protection against

penetration at a force of at least 100 N

— level 1U: knee protectors suitable for use on even or uneven surfaces providing protection against

penetration at a force of at least 100 N.
