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., H332: Gesundheitsschädlich bei Einatmen., P301+P310: Bei Verschlucken: Sofort Giftinformationszentrum, Arzt oder … anrufen.
