First Aid:INGEST: CALL MD IMMED . INHAL: IF SYMPS OF PULMONARY
INVOLVEMENT DEVELOP (COUGH, WHEEZ, SHORTNESS OF BREATH, ETC),
REMOVE FROM EXPOS & SEEK MED ATTN. SKIN: IF IRRIT/RASH OCCURS,
THOROUGHLY WASH AFFECTED AREA W/SOAP & WATER & ISOLATE FROM EXPOS.
IF IRRIT/RASH PERSISTS, SEEK MED ATTN. EYES: IF IRRIT OCCURS, FLUSH
W/LARGE AMOUNTS OF WATER FOR AT LEAST 15 MIN. IF IRRIT PERSISTS,
SEEK MED ATTN.

Extinguishing Media:USE A DRY POWDER EXTINGUISHER APPROPRIATE FOR USE
WITH METAL DUST FIRES.

Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

Handling and Storage Precautions:MAINTAIN GOOD HOUSEKEEPING PROCEDURES
TO PREVENT DUST ACCUMULATION DURING GRINDING. AVOID DUST INHALATION
AND DIRECT SKIN CONTACT WITH DUST.
Other Precautions:CLEAN UP USING METHODS WHICH AVOID DUST GENERATION
SUCH AS VACUUM (W/APPROP FILTER TO PVNT AIRBORNE DUST LEVELS WHICH
EXCEED PEL/TLV), WET DUST MOP OR WET CLEAN-UP. IF AIRBORNE DUST IS
GENERATED, USE AN APPROP NIOSH APPRVD RESP. (ING 6)

Respiratory Protection:USE APPROP NIOSH APPRVD RESP IF AIRBORNE DUST
CONCS EXCEED APPROP PEL OR TLV. ALL APPROP REQS AS SET FORTH IN 29
CFR 1910.134 SHOULD BE MET. PROTECTION FACTORS FOR RESPS RECOM ARE
BASED UPON THOSE AS LISTED IN 29 CFR 1910.1001(G), (ING 10)
