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.
