PREVENTATIVE MEASURES
========================================================================
Ventilation:
Use adequate general or local exhaust ventilation to keep fume or dust levels as low as possible.
Respiratory Protection:
None required where adequate ventilation conditions exist. If airborne concentration is high, use an
appropriate respirator or dust mask.
Eye/Skin Protection: Safety goggles, uniform, butyl rubber gloves are recommended.
Storage Requirements:
Keep container tightly closed. Store separately and away from flammable and combustible materials.
Isolate from incompatible materials.
