Dies schließt sowohl die Anwendung durch Eintauchen als auch durch Sprühverfahren in ein oder mehreren Prozessschritten ein. Ein herausragendes Merkmal dieser Norm ist ihre klare Struktur, die eine Kombination mit EN 12921-1 vorsieht. Durch gemeinsame Anwendung wird sichergestellt, dass sämtliche signifikanten Gefahren, die bei der Nutzung von Reinigungsmaschinen auftreten können, abgedeckt werden. Die spezifischen Anforderungen, die in dieser Norm festgelegt sind, haben Vorrang vor den entsprechenden Anforderungen in EN 12921-1, was die Relevanz der Norm für die Sicherheitsstandards im Bereich der Industrie deutlich unterstreicht. Zusätzlich wird im Dokument die Notwendigkeit aufgeführt, EN 12921-3 zu berücksichtigen, wenn brennbare Dämpfe aus wasserbasierten Reinigungsflüssigkeiten freigesetzt werden. Dies bietet einen zusätzlichen Schutz, insbesondere in Umgebungen, in denen das Risiko explosiver Atmosphären besteht. Die Kriterien für wasserbasierte Reinigungsflüssigkeiten, die halogenierte Lösungsmittel in Mengen über 2 % des Volumens enthalten, werden als gefährlich eingestuft, was die Bedeutung dieser Norm im Hinblick auf den Arbeitsschutz weiter verstärkt. Es ist ebenso wichtig zu beachten, dass die Norm nicht auf Maschinen und zugehörige Ausrüstungen anwendbar ist, die aus dem Geltungsbereich von EN 12921-1 ausgeschlossen sind. Des Weiteren gilt sie nicht für Reinigungsmaschinen, die vor der Veröffentlichung der Norm durch CEN hergestellt wurden, was ihre Fachigkeit und Aktualität sichert. Insgesamt bietet die EN 12921-2:2005+A1:2008 eine entscheidende Richtlinie für Hersteller und Betreiber von Reinigungsmaschinen und gewährleistet durch ihre präzisen Anforderungen und Richtlinien ein hohes Maß an Sicherheit beim Umgang mit wasserbasierten Reinigungsflüssigkeiten in der Industrie.
