                   Precautions for Safe Handling and Use

===========================================================================

Steps If Matl Released/Spill: AVOID USING COMPRESSED AIR TO MANEUVER

SPILLS/LEAKS OF FINE MATERIAL. FINE MATERIAL SHOULD BE SWEPT UP/VACUUMED.

NO PROBLEM IS ASSOCIATED WITH SPILLS/LEAKS OF LUMP MATERIAL. KEEP WET

MATERIAL SEPARATED FROM DRY MATERIAL. *

Neutralizing Agent: NONE SPECIFIED BY MANUFACTURER. *

Waste Disposal Method: AVOID REPACKING WET MATERIAL IN SEALED CONTAINERS.

DISPOSE OF I/A/W APPLICABLE FEDERAL, STATE, AND LOCAL REGULATIONS. *

Precautions-Handling/Storing: EXCLUDE CONT W/MOISTURE & ACIDS AS MUCH AS

POSS. CALCIUM-SILICON ALLOYS SHOULD BE KEPT AWAY FROM SPARKS, HEAT & OPEN

FLAMES IN A WELL VENTD AREA. *

Other Precautions: MILLING: SPECIAL PREC, SUCH AS USE OF INERT ATMOSPHERE,

SHOULD BE USED WHEN SIZING TO MINUS 8 MESH. MINIMIZE AND CONTROL DUSTY

OPERATIONS. GRINDING WET MATL MAY BE HAZ DUE TO THE POSSIBILITY OF HYDROGEN

EVOLUTION. *

===========================================================================

                             Control Measures

===========================================================================

Respiratory Protection: IN DUSTY AREAS, USE NIOSH/MSHA APPROVED SCHEDULE

21C RESPIRATOR. *

Ventilation: LOCAL FOR DUSTY AREAS. PROVIDE VENTILATION DURING STORAGE OR

HANDLING OF MOIST MATERIAL. *

Protective Gloves: IMPERVIOUS GLOVES (FP N). * 

Eye Protection: ANSI APVD CHEMICAL SAFETY GOGGLES (FP N) * 

Other Protective Equipment: AS WITH OTHER METAL DUSTS AVOID CONTAMINATION

OF WORK CLOTHING. *

Work Hygienic Practices: NONE SPECIFIED BY MANUFACTURER. *

Suppl. Safety & Health Data: MP:>1292F,>700C. EXTING MEDIA: BURN ITSELF

OUT. DO NOT DISTURB METAL WHILE EXTING FIRE. EXPLO HAZ: READILY, GENERATE
