concentration level above TLV. Check TLV on the MSDS and with local authorities.
Section 7: Handling and Storage Precautions:
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. Avoid contact
with eyes 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.
Storage: Keep
container dry. Keep in a cool place. Ground all equipment containing material.
Keep container tightly closed. Keep in a cool, well-ventilated place.
Combustible materials should be stored away from extreme heat and away from
strong oxidizing agents.
Section 8: Exposure Controls/Personal Protection Engineering
Controls:
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 to avoid inhalation of the product.
Suggested protective clothing might not be sufficient; consult a specialist
BEFORE handling this product.
