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., H330: Lebensgefahr bei Einatmen., H340: Kann genetische Defekte verursachen., H350: Kann Krebs erzeugen., H360Fd: Kann die Fruchtbarkeit beeinträchtigen. Kann vermutlich das Kind im Mutterleib schädigen., H372: Schädigt die Organe bei längerer oder wiederholter Exposition., H410: Sehr giftig für Wasserorganismen mit langfristiger Wirkung., P201: Vor Gebrauch besondere Anweisungen einholen., P273: Freisetzung in die Umwelt vermeiden., P304+P340: Bei Einatmen: Die Person an die frische Luft bringen und für ungehinderte Atmung sorgen., P309+P310: Bei Exposition oder Unwohlsein: Sofort Giftinformationszentrum oder Arzt anrufen.
