EN 381-11:2002 (E)3ForewordThis document (EN 381-11:2002) has been prepared by Technical Committee CEN /TC 162, "Protective clothingincluding hand and arm protection and lifejackets", the secretariat of which is held by DIN.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by May 2003, and conflicting national standards shall be withdrawn at the latest byMay 2003.This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree Trade Association, and supports essential requirements of EU Directive(s).For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.In this European Standard the Annex A is informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,Sweden, Switzerland and the United Kingdom.



EN 381-11:2002 (E)4IntroductionThis European Standard forms part of a series concerned with personal protective equipment designed to protectagainst the risks arising from the use of hand-held chainsaws.Accidents occur due to a number of complex reasons, but a common factor is incorrect use of the chainsaw. Theimportance of correct training and proper use of a chainsaw in preventing accidents cannot be underestimated.In some countries chainsaw users adopt working practices, which together with training makes the use of upperbody protectors unnecessary. These usually include the instruction to hold the chainsaw with both hands and touse the chain brake if it becomes necessary to stop cutting. It is often found that for ergonomic reasons it isimpractical to protect the upper body.All parts of the upper body have been shown to be at risk when using a chainsaw.In this European standard, specifications for the protective coverage and performance of the upper body protectorsare given. No personal protective equipment can ensure a 100% protection against cutting from a hand-heldchainsaw.Nevertheless, experience has shown that it is possible to design personal protective equipment that offers a certaindegree of protection.Different functional principles may be applied in order to give protection.These include:a) chain slipping: on contact the chain does not cut the material;b) clogging: fibres are drawn by the chain into the drive sprocket and block chain movement;c) chain braking: fibres have a high resistance to cutting and absorb rotational energy, thereby reducing the chainspeed.Often more than one principle is applied in chainsaw protective clothing. Upper body protectors meeting thisstandard are meant to be used whilst working off the ground, and where risk assessment shows that there is asignificant risk to be cut by the moving chain on the upper part of the body such as when working from a sky lift andcarrying out tree surgery.



EN 381-11:2002 (E)51 ScopeThis Part of this European Standard, specifies requirements for the protection offered by upper body protectorsagainst cutting by a hand-held chainsaw assessed by the test methods given in EN 381-10:2002. The requirementsrelating to ergonomic properties, identification, marking and information supplied by the manufacturer includingselection criteria and instructions for use are also specified.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.
