Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water

on the contaminated surface and allow to evacuate through the sanitary system.


Section 7: Handling and Storage


Keep locked up.. Keep away from heat. Keep away from sources of ignition. Empty containers pose a fire risk,

evaporate the residue under a fume hood. Ground all equipment containing material. Do not ingest. Do not

breathe dust. Wear suitable protective clothing. If ingested, seek medical advice immediately and show the

container or the label. Keep away from incompatibles such as oxidizing agents, reducing agents, acids, alkalis.
