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+H331: Giftig bei Verschlucken oder Einatmen., H373: Kann die Organe schädigen bei längerer oder wiederholter Exposition., H410: Sehr giftig für Wasserorganismen mit langfristiger Wirkung., P260: Staub / Rauch / Gas / Nebel / Dampf / Aerosol nicht einatmen., P301+P330+P331+P310: Bei Verschlucken: Mund ausspülen. Kein Erbrechen herbeiführen. Sofort Giftinformationszentrum oder Arzt anrufen., P304+P340+P311: Bei Einatmen: Die Person an die frische Luft bringen und für ungehinderte Atmung sorgen. Giftinformationszentrum oder Arzt anrufen., P403+P233: Behälter dicht verschlossen an einem gut belüfteten Ort aufbewahren.
