BS EN 14404
Arc Flash & Protective Clothing Standards
BS EN 14404 Standard relates to personal protective equipment, knee protectors for work in the kneeling position. ProGARM® produces safety garments that are certified in accordance with the BS EN 14404 Type 2 standard. This EN Standard relates to trousers and coveralls which offer kneepad pockets to protect the wearer when kneeling.
ABOUT THIS EN STANDARD
EN 14404 only applies in combination with certified knee pads and a garment that has been assessed. All ProGARM® workwear garments with knee pockets comply with EN 14404 and have been assessed accordingly by a notified body.
The measurements prescribed for kneepads depend on the size of the garment in which they are used. The ProGARM® Gel Foam kneepad is our recommended kneepad for use in our garments to ensure the pad fits the pocket and offers protection for wearers from short to long leg lengths.
There are three properties of knee protectors that are tested – these are Penetration Resistance, Force Distribution and Shock Absorption. Two levels of protection can be provided. The ProGARM® Gel Foam Knee Pad has been tested according to and meets the requirements for EN14404 Level 1.
Level 1: This level requires knee pads to provide protection on a surface on which the wearer will not generally risk injury from lying objects more than 1 cm high. Penetration resistance of at least 100 N.
Level 2: This level requires kneepads to be able to withstand use under heavy conditions, such as kneeling on stones in mines and quarries. Penetration resistance of at least 250 N. View further information about Arc Flash Clothing Standards.
BS EN 14404 | Standard Overview
Personal protective clothing. Knee protectors for work in the kneeling position.
The following is an excerpt from BS EN 14404:2004+A1:2010 EN 14404:2004+A1:2010 (E)
This British Standard is the UK implementation of EN 14404:2004+A1:2010. It supersedes BS EN 14404:2004 which is withdrawn.
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 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, but knee protectors should 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 particularly 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. Their size should ensure that they protect the knees during movement.’
