It applies to the design and manufacture of all parts of the equipment including hoods, ducting, filter units, air movers, systems that inform of unsafe operation and workplace practices to ensure safe working with regard to exposure.
Significant hazards are listed in Clause 4. It does not cover electrical, mechanical and pneumatic hazards.
ISO 15012-4:2016 is applicable to the following:
- local exhaust ventilation systems (LEV);
- mobile and stationary equipment.
It is not applicable to the following:
- general ventilation, air make up or air movement systems;
- air conditioning systems;
- separation of gases generated by or used by welding and allied processes;
- LEV used for welding and allied processes that generate reactive potentially explosive particles and atmospheres;
- grinding dust.
ISO 15012-4:2016 applies to systems designed and manufactured after its publication.

Arbeits- und Gesundheitsschutz beim Schweißen und bei verwandten Verfahren - Einrichtungen zum Erfassen und Abscheiden von Schweißrauch - Teil 4: Allgemeine Anforderungen (ISO 15012-4:2016)

Einrichtungen zum Erfassen und Abscheiden von Schweißrauch, wie z. B. Punktabsaugsysteme (LEV) oder Umhausungen zum Absaugen von Schweißrauch, sind Sicherheitsteile. Funktionsfehler können Gesundheitsschäden bei den Schweißern hervorrufen.
Einrichtungen zum Erfassen und Abscheiden von Schweißrauch bestehen aus Erfassungseinrichtungen, Rohrleitungen, Filtereinheiten und Gebläsen Die Dimensionierung dieser Bauteile hat Einfluss auf die Funktion des gesamten Systems. Dies ist vom Konstrukteur zu berücksichtigen.
Diese Internationale Norm legt zur Erfüllung der Sicherheitsfunktionen die Anforderungen an Einrichtungen zum Erfassen und Abscheiden von Schweißrauch fest. Eine derartige Einrichtung kann ein Punktabsaugsystem oder ein Umhausung sein. Diese Norm behandelt keine grundlegenden Sicherheitsaspekte für die Einrichtung als Maschine, wie elektrische, mechanische und pneumatische Gefährdungen.
Diese Norm gilt für:
   LEV (Punktabsaugsystemen);
   Umhausungen, die für Personen unzugänglich sind, wenn sie in Betrieb sind;
   mobile und stationäre Systeme.
Diese Norm gilt nicht für:
   Anlagen zur allgemeinen Belüftung, Luftaufbereitung oder Luftumwälzsysteme;
   Klimaanlagen;
   Abscheidung von Gasen, die beim Schweißen entstehen oder verwendet werden;
   Punktabsaugsysteme die für die Beseitigung von reaktiven, potentiell explosiven Partikeln und/oder Gasen verwendet werden, die beim Schweißen und den verwandten Verfahren auftreten können.
Diese Norm gilt für Einrichtungen, die nach Veröffentlichung dieser Norm konstruiert wurden.

Les phénomènes dangereux significatifs sont énumérés dans l'Article 4. La présente norme ne traite pas des phénomènes dangereux électriques, mécaniques et pneumatiques.
L'ISO 15012-4 :2016 est applicable:
- aux systèmes de ventilation par aspiration localisée (LEV);
- aux équipements mobiles et fixes.
Elle ne s'applique pas:
- aux systèmes de ventilation générale, d'air d'appoint ou de déplacement d'air;
- aux systèmes de conditionnement d'air;
- à la filtration des gaz produits par ou utilisés pour les procédés de soudage et les techniques connexes;
- aux LEV utilisés pour le soudage et les techniques connexes qui produisent des particules et atmosphères réactives, potentiellement explosives;
- à la poussière de meulage.
L'ISO 15012-4 :2016 s'applique aux systèmes conçus et fabriqués après sa publication.
