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: H302: Gesundheitsschädlich bei Verschlucken., H332: Gesundheitsschädlich bei Einatmen., H360Df: Kann das Kind im Mutterleib schädigen. Kann vermutlich die Fruchtbarkeit beeinträchtigen., H373: Kann die Organe schädigen 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., P308+P313: Bei Exposition oder falls betroffen: Ärztlichen Rat einholen / ärztliche Hilfe hinzuziehen., P501: Inhalt / Behälter … zuführen.
