Safety storage, transportation and operation specifications

Storage requirements: Refrigerant R404A should be stored in a cool and ventilated place, away from direct sunlight, and the ambient temperature should not exceed 40 ℃; Keep away from sources of fire and heat, and store in isolation from oxidants and flammable materials;

Transporthinweise: Stahlzylinder mit dem Kältemittel R404A sind Druckbehälter und sollten beim Transport mit Vorsicht behandelt werden, um Beschädigungen der Ventile zu vermeiden; die Transportvorschriften für Hochdruckbehälter sind unbedingt einzuhalten;

Arbeitsschutz: Schutzbrille, kältebeständige Handschuhe und Schutzkleidung tragen; direkten Hautkontakt mit Flüssigkeiten vermeiden (da dies zu Erfrierungen führen kann);

Notfallmaßnahmen:

Bei Inhalationsüberdosis: Begeben Sie sich an einen Ort mit frischer Luft, achten Sie auf ungehinderte Atmung und suchen Sie gegebenenfalls ärztliche Hilfe auf;

Hautkontakt: Sofort 15 Minuten lang mit warmem Wasser abspülen. Bei Erfrierungen umgehend einen Arzt aufsuchen;

Maßnahmen bei Leckagen: Nicht beteiligtes Personal evakuieren, belüften und Behälter mit Sprühwasser kühlen, um eine Explosion zu verhindern.
