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. 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
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.
