ingest. Do not breathe dust. Wear suitable protective clothing. In case of insufficient ventilation, wear suitable
respiratory equipment. If ingested, seek medical advice immediately and show the container or the label. Avoid
contact with skin and eyes. Keep away from incompatibles such as oxidizing agents, acids, alkalis.
Storage: Keep container tightly closed. Keep container in a cool, well-ventilated area.
Section 8: Exposure Controls/Personal Protection

Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below
recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to
airborne contaminants below the exposure limit.
Personal Protection:
Splash goggles. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent.
Gloves.
Personal Protection in Case of a Large Spill:
Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used
