Routes of Entry: Inhalation:YES  Skin:NO  Ingestion:NO
Reports of Carcinogenicity:NTP:YES    IARC:YES	  OSHA:NO
Health Hazards Acute and Chronic:ACUTE: ALUMINUM & SILICON DUSTS ARE
    CONSIDERED NUISANCE PARTICULATES WHICH HAVE LITTLE ADVERSE EFTS ON
    LUNGS WHEN EXPOS ARE KEPT UNDER REASONNABLE CTL. SKIN: CAN CAUSE
    BURNS. EYE: ALUMINUM DUST CAN IR RITATE EYES (MECH ABRASION).
    ALUMINUM FUMES GENERATED DURING WELD/MELT OPERATIONS PRESENT LOW
    HLTH (EFTS OF OVEREXP)
Explanation of Carcinogenicity:CHROMIUM:IARC MONOGRAPHS, VOL 49, PG 49,
    1990:GRP 1. NTP 6TH ANNUAL REPORT ON CARCINS, 1991: KNOWN TO BE
    CARCIN 
Effects of Overexposure:HLTH HAZ: RISKS. MIG WELD/PLASMA ARC CUTTING OF
    ALUMINUM ALLOYS CAN GENERATE OZONE, NITRIC OXIDES & ULTRAVIOLET
    RADIATION. OZONE OVEREXP MAY RSLT IN MUC MEMB IRRIT/PULM
    DISCOMFORT. UV RADIA CAN CAUSE  SKIN ERYTHEMA & WELDERS FLASH. HIGH
    CONC OF FRESHLY FORMED FUMES OF MAGNESIUM OXIDES & MANGANESE OXIDES
    & CAN (SUPDAT)

=======================  First Aid Measures  =======================

First Aid:INHAL: GO TO A VENTILATED AREA. IF DISCOMFORT PERSISTS, GET
    MED ATTN. REMOVE TO FRESH AIR. SUPPORT BRTHG (GIVE O*2/ARTF RESP) .
    SKIN: RINSE WITH PLENTY OF COLD WATER. IF BURN IS SEV, SEEK MED AT
    TN. EYE: FLUSH THORO W/WATER FOR @ LST 15 MIN. IF IRRIT PERSISTS,
    CONSULT A PHYS. INGEST: CALL MD IMMED .

=====================  Fire Fighting Measures  =====================

Extinguishing Media:IN CASE OF AN ALUMINUM FIRE, USE A CLASS D DRY
    POWDER EXTING/DRY SAND. DO NOT USE WATER/HALOGENATED EXTING MEDIA.
Fire Fighting Procedures:WEAR NIOSH/MSHA APPROVED SCBA & FULL PROT
    EQUIPMENT.
Unusual Fire/Explosion Hazard:NOT A FIRE HAZ UNLESS IN FINELY DIVIDED
    FORM. ALUMINUM DUST CAN PRESENT A SEVERE EXPLOSION HAZARD IF
    DISPERSED IN AIR.

==================  Accidental Release Measures  ==================

Spill Release Procedures:RECYCLE. FINELY-DIVIDED ALUMINUM MAY BE
    REACTIVE & ITS HAZARD CHARACTERISTIC SHOULD BE DETERMINED PRIOR TO
    DISPOSAL.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

======================	Handling and Storage  ======================

Handling and Storage Precautions:INGOTS & METAL SCRAP SHOULD BE THORO
    DRIED PRIOR TO REMELTING DUE TO EXPLO HAZ. CHECK METAL TEMP W/USUAL
    METHS BEFORE HNDLG IT.
Other Precautions:HOT ALUMINUM DOES NOT PRESENT ANY WARNING COLOR
    CHANGE; SPECIAL CAUTION SHOULD THEREFORE BE TAKEN IN CASE METAL
    WOULD BE HOT. FOR MORE INFO ON HNDLG & STOR OF ALUMINUM, REQUEST A
    COPY OF "GUIDELINES F OR HNDLG MOLTEN ALUMINUM" & (ING 6)

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:USE NIOSH/MSHA APPROVED RESPIRATOR W/DUST
    FILTER/DUST MASK, FOR CONCENTRATIONS ABOVE EXPOSURE LIMITS. MOLTEN
    METAL HNDLG REQS USE OF BOTH PRIMARY & SECONDARY PERSONAL PROT
    EQUIP. REFER TO "ALUMINUM AS SOCIATION" GUIDELINES.
Ventilation:SPECIAL VENT PROVISIONS MAY BE REQD TO AVOID EXPLO HAZS.
    SEE "NATL FIRE PROT ASSOC" CODES, NFPA 65 AND 651.
Protective Gloves:IMPERVIOUS GLOVES .
Eye Protection:ANSI APPRVD CHEM WORKERS GOGGLES .
Other Protective Equipment:NONE SPECIFIED BY MANUFACTURER.
