Personal fall protection equipment - Descender devices for rescue
This European Standard specifies requirements, test methods, marking and information to be supplied by the manufacturer for descender devices, which include descent lines (hereinafter referred to as lines), intended for rescue and to protect against falls in a rescue system, which is a personal fall protection system. This European Standard does not specify requirements for descender devices that are used for descending in mountaineering, rope access or work positioning systems.
NOTE A descender device which enables the user to rescue himself and which conforms to this European Standard is personal protective equipment (PPE).
Persönliche Absturzschutzausrüstung - Abseilgeräte zum Retten
Diese Europäische Norm legt Anforderungen, Prüfverfahren, Kennzeichnung und Informationen des Herstellers für Abseilgeräte, einschließlich des Tragmittels zum Abseilen (im Folgenden kurz als Tragmittel bezeichnet), zur Rettung und zum Schutz gegen Absturz in einem Rettungssystem, das ein persönliches Absturzschutzsystem ist, fest. Diese Europäische Norm legt keine Anforderungen für Abseilgeräte fest, die im Bergsport, bei seilunterstützten Arbeiten oder bei Systemen der Arbeitsplatzpositionierung benutzt werden. ANMERKUNG Ein Abseilgerät, das es dem Benutzer ermöglicht, sich selbst zu retten, und das dieser Europäischen Norm entspricht, ist eine persönliche Schutzausrüstung (PSA).
Équipement de protection individuelle contre les chutes - Descendeurs pour sauvetage
La présente Norme européenne prescrit les exigences, les méthodes d’essai, le marquage et les informations à fournir par le fabricant (notice d’information du fabricant) relatifs aux descendeurs, lesquels comprennent les supports d’assurage pour la descente (appelés ci-après supports d’assurage), destinés au sauvetage et à assurer une protection contre les chutes dans un système de sauvetage, qui constitue un système de protection individuelle contre les chutes. La présente Norme européenne ne spécifie aucune exigence concernant les descendeurs qui sont utilisés en alpinisme/en escalade ou avec les systèmes d'accès par corde ou de maintien au poste de travail.
NOTE Un descendeur qui permet à l'utilisateur de se sauver lui-même et qui est conforme à la présente Norme européenne est un équipement de protection individuelle (EPI).
Osebna varovalna oprema za zaščito pred padci z višine - Naprave za spuščanje ob reševanju
Ta evropski standard določa zahteve, preskusne metode, označevanje in informacije, ki jih mora zagotoviti proizvajalec za naprave za spuščanje, vključno z vodom za spuščanje, namenjenim izključno za reševanje, ki se uporabljajo v povezavi z drugo opremo, npr. pasovi za celo telo (EN 361), reševalnimi pasovi (EN 1497). Ta evropski standard ne določa zahtev za naprave za spuščanje, ki se uporabljajo za druge namene kot reševanje, npr. za gorništvo, dostopanje z vrvjo in delovne namestitvene sisteme. Naprave za spuščanje so lahko namenjene uporabi za eno ali dve osebi hkrati.
