PREVENTATIVE MEASURES
========================================================================
Ventilation: Use general or local exhaust ventilation to meet TLV requirements.
Respiratory Protection:
None required where adequate ventilation conditions exist. If airborne concentration exceeds TLV, a
self-contained breathing apparatus is advised.
Eye/Skin Protection: Safety goggles, uniform, apron, rubber gloves are recommended.
Storage Requirements:
Keep container tightly closed. Store away from water or locations where water may be used to
extinguish fire.

========================================================================
Steps To Be Taken In The Event Of A Spill Or Discharge:
Wear self-contained breathing apparatus and full protective clothing. With clean shovel, carefully place
material into clean, dry container and cover; remove from area. Flush spill area with water. Do not get
water inside container.
