19、ectly the related work activity can be achieved by the use of personal protective equipment.Equipment when manufactured according to this standard is designed to either secure the user safely in position atthe point of work (work positioning); or, prevent the user from reaching a position where a fa

20、ll can occur (restraint).It is essential to note that such personal equipment by design does not meet the requirements necessary for thepurposes of fall arrest, it may be necessary to supplement it with collective or personal means of protection againstfalls from a height, and its safe use, in pract

21、ice, relies upon the effective training and instruction of the user.1 ScopeThis European standard applies to belts and lanyards intended for the purpose of work positioning or restraint. Itspecifies the requirements, testing, marking and information supplied by the manufacturer.2 Normative reference

27、 load bearing element provided for the connection of other components.Page 4EN 358:19993.2 ComponentA part of a system at a point of sale by the manufacturer, supplied with packaging, marking and information suppliedby the manufacturer. Body supports (including waist belts) and lanyards are examples

28、 of components of systems.(see EN 363)3.3 ElementA part of a component or a sub-system. Ropes, webbing, attachment elements, fittings and anchorage lines areexamples of elements.3.4 RestraintA technique whereby a person is prevented by means of personal protective equipment from reaching zones where

29、the risk of a fall from a height exists.3.5 Waist beltA body support that encircles the body at the waist.3.6 Work positioningA technique that enables a person to work supported by personal protective equipment in tension in such a way thata fall is prevented.3.7 Work positioning lanyardA component

30、used to connect a waist belt to an anchor point, or to a structure by encircling it, as a means ofsupport. 4 Requirements4.1 Design and construction4.1.1 Waist belt4.1.1.1 A waist belt shall be designed to enable the wearer to perform his work without undue discomfort andremain secure against the ha

31、zard of a fall from a height. Essential fastening and adjustment elements shall remainaccessible to the wearer and shall operate effectively when manipulated by hand.4.1.1.2 A waist belt shall be not less than 43 mm wide and shall be capable of adjustment to fit the wearer. Thewaist belt shall have

32、at least one attachment element intended for the connection of load bearing components. Thewaist belt shall meet the performance requirements specified in 4.2.4.1.1.3 The fastening and adjustment elements of a waist belt shall be designed and constructed so that whencorrectly fastened, involuntary r

33、elease or opening of the element cannot occur. When fastening or adjustmentelements can be secured in more than one manner, then the waist belt shall comply with the performancerequirements of this standard when the elements are secured in each available manner.4.1.1.4 It shall be possible to carry

34、out a visual inspection of the waist belt and all its attachments even when thebelt is incorporated into a garment or if it is a component in a full body harness.4.1.1.5 A waist belt not fitted with a back support and intended for work positioning purposes shall be not less than80 mm wide.4.1.1.6 A
