26、on Kneeling is an unnatural working position. Without knee protectors, workers may suffer discomfort and 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 a

27、re 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 inte

28、rvals 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

29、 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, but knee protectors shoul

30、d slow the process. 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 partic

31、ularly wet cement, should take this into account and provide adequate protection, as does footwear. Knee protectors incorporated into trousers or attached to trousers or worn over trousers or on the bare knees should remain in place while kneeling down, and while shuffling (walking) on the knees. Th

32、eir size should ensure that they protect the knees during movement. !deleted text“ DIN EN 14404:2010-05 EN 14404:2004+A1:2010 (E) 5 1 Scope This document specifies the requirements for knee protectors for use in a kneeling position.
