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: H335: Kann die Atemwege reizen., P261: Einatmen von Staub / Rauch / Gas / Nebel / Dampf / Aerosol vermeiden., P304+P340: Bei Einatmen: Die Person an die frische Luft bringen und für ungehinderte Atmung sorgen., P312: Bei Unwohlsein Giftinformationszentrum, Arzt oder … anrufen., P403+P233: Behälter dicht verschlossen an einem gut belüfteten Ort aufbewahren., P405: Unter Verschluss aufbewahren., P501: Inhalt / Behälter … zuführen. |
