Safety Instructions

Industrial chemicals are often present in powder form and therefore often contain much higher dangers than natural, crystalline substances. These hazard statements refer to the classification of industrially used chemical compounds that may also occur in this natural mineral. The hazard classification makes no claim to completeness.




Safety classes: H301: Giftig bei Verschlucken., H315: Verursacht Hautreizungen., H317: Kann allergische Hautreaktionen verursachen., H319: Verursacht schwere Augenreizung., H330: Lebensgefahr bei Einatmen., H335: Kann die Atemwege reizen., H350i: Kann bei Einatmen Krebs erzeugen., H372: Schädigt die Organe bei längerer oder wiederholter Exposition., H411: Giftig für Wasserorganismen, mit langfristiger Wirkung.
