Protective clothing against dangerous solid, liquid and gaseous chemicals, including liquid and solid aerosols - Part 2: Performance requirements for Type 1 (gas-tight) chemical protective suits for emergency teams (ET)

This European Standard specifies the minimum requirements, test methods, marking and information supplied by the manufacturer, for ventilated and non-ventilated gas-tight chemical protective suits for use by emergency teams (ET).
It specifies full body personal protective ensembles to be worn for protection against solid, liquid and gaseous chemicals, including liquid and solid aerosols. Chemicals such as violently air sensitive reagents, unstable explosives and cryogenic liquids have not been considered since protection against these additional hazards is beyond the scope of this standard.
This standard does not establish minimum criteria for protection for non-chemical hazards, e. g. radiological, fire, heat, explosive hazards, infective agents.. This type of equipment is not intended for total immersion in liquids.
The seams, joins and assemblages attaching the accessories are included within the scope of this standard. The performance criteria for the accessories, gloves, boots or respiratory protective equipment are given in other standards.
Particulate protection is limited to physical penetration of the particulates only.

Schutzkleidung gegen gefährliche feste, flüssige und gasförmige Chemikalien, einschließlich Flüssigkeitsaerosole und feste Partikel - Teil 2: Leistungsanforderungen für Typ 1 (gasdichte) Chemikalienschutzkleidung für Notfallteams (ET)

Diese Europäische Norm legt die Mindestanforderungen, Prüfverfahren, Kennzeichnung und vom Hersteller zur Verfügung gestellten Informationen für belüftete und unbelüftete gasdichte Chemikalienschutzanzüge zur Benutzung durch Notfallteams (ET) fest.
Sie legt persönliche Ganzkörper-Schutzkleidungssysteme fest, die zum Schutz gegen feste, flüssige und gasförmige Chemikalien, einschließlich Flüssigkeitsaerosole und feste Partikel, zu tragen sind. Chemikalien, wie stark luftempfindliche Reagenzien, instabile Explosivstoffe und kryogene Flüssigkeiten, wurden nicht berücksichtigt, da der Schutz gegen diese zusätzlichen Gefahren außerhalb des Anwendungsbereichs dieser Norm liegt.
Diese Norm legt keine Mindestanforderungen an den Schutz vor nicht-chemischen Gefahren, z. B. Strahlung, Feuer, Hitze, explosive Gefahren, Infektionserreger, fest. Diese Art der Ausrüstung ist nicht für das vollständige Eintauchen in Flüssigkeiten vorgesehen.
Die Nähte, Verbindungen und Verbünde zum Anbringen der Zubehörteile liegen innerhalb des Anwendungsbereichs dieser Norm. Die Leistungsanforderungen für Zubehörteile, Handschuhe, Schutzschuhe oder Atemschutzgeräte sind in anderen Normen angegeben.
Der Schutz vor Partikeln ist auf das physische Durchdringen der Partikel begrenzt.

Vêtements de protection contre les produits chimiques dangereux solides, liquides et gazeux, y compris les aérosols liquides et les particules solides - Partie 2: Exigences de performance des combinaisons des protections chimiques étanches aux gaz (Type 1) destinés aux équipes de secours (ET)

La présente Norme européenne définit les exigences minimales, les méthodes d’essai, le marquage ainsi que les informations fournies par le fabricant concernant les combinaisons de protection chimique ventilées et non ventilées étanches aux gaz, destinées à être utilisées par des équipes de secours (ET).
Elle décrit les combinaisons individuelles protégeant tout le corps, destinées à être portées pour se prémunir contre les produits chimiques solides, liquides et gazeux, y compris les aérosols liquides et les particules solides. Les produits chimiques tels que les réactifs ultra-sensibles à l'air, les explosifs instables et les liquides cryogéniques n'ont pas été pris en compte, car la protection contre les dangers supplémentaires qu'ils présentent sort du domaine d'application de la présente norme.
La présente norme n'établit pas de critères minimaux de protection contre les risques non chimiques, par exemple les risques radiologiques, d’incendie, d’explosion ou liés à la chaleur et les agents infectieux. Ce type d’équipement n’est pas prévu pour une immersion totale dans des liquides.
Les coutures, les jonctions et les assemblages servant à fixer les accessoires sont inclus dans le domaine d’application de la présente norme. Les critères de performance pour les accessoires, les gants, les bottes ou l’équipement de protection respiratoire sont mentionnés dans d’autres normes.
La protection contre les particules se limite exclusivement à la pénétration physique des particules.

Varovalna obleka pred nevarnimi trdnimi, tekočimi in plinskimi kemikalijami, vključno s tekočimi in trdnimi aerosoli - 2. del: Varnostne zahteve za kemijsko varovalno obleko, neprepustno za plin (tip 1), za intervencijske enote

Ta evropski standard določa minimalne zahteve, preskusne metode, označevanje in informacije, ki jih mora zagotoviti proizvajalec, za prezračevano in neprezračevano kemijsko varovalno obleko, neprepustno za plin, ki jo uporabljajo intervencijske enote.
Določa komplete osebnih varovalnih oblačil za celotno telo, ki se nosijo za zaščito pred trdnimi, tekočimi in plinskimi kemikalijami, vključno s tekočimi in trdnimi aerosoli. Kemikalije, kot so reagenti, ki so zelo občutljivi na zrak, nestabilen eksplozivni material in kriogene tekočine, niso obravnavane, ker zaščita pred temi dodatnimi nevarnostmi presega področje uporabe tega standarda.
Ta standard ne vzpostavlja minimalnih meril za zaščito pred nekemičnimi nevarnostmi, kot je radiološka nevarnost, nevarnost nastanka požara, nevarnost zaradi vročine, nevarnost eksplozije in nevarnost povzročiteljev infekcije. Ta vrsta opreme ni namenjena popolni potopitvi v tekočine.
Šivi, spoji in sestavi, s katerimi je pritrjena dodatna oprema, spadajo na področje uporabe tega standarda. Merila učinkovitosti za dodatno opremo, rokavice, škornje ali dihalno varovalno opremo so podana v drugih standardih.
Zaščita pred delci je omejena samo na fizično penetracijo delcev.
