=====================  Hazards Identification  =====================

LD50 LC50 Mixture:NO DATA PROVIDED BY MANUFACTURER
Routes of Entry: Inhalation:NO	Skin:YES  Ingestion:NO
Health Hazards Acute and Chronic:EXPOSURE TO MAGNESIUM METAL OR OXIDE
    DUST SHOULD BE A LOW HEALTH RISK BY INHALATION AND SHOULD BE
    TREATED AS A NUISANCE DUST. EXPOSURE TO MAGNESIUM OXIDE FUME AND
    SUBSEQUENT BURNING CAN RESULT IN META L FUME FEVER. THE TEMPORARY
    SYMPTOMS CANINCLUDE FEVER, CHILLS, NAUSEA, VOMITING AND MUSCULAR
    PAIN. ONSET OF SYMPTOMS OCCURS 4-12 HOURS AFTER EXPOSURE. EYES: MAY
    CAUSE BURNS AND CORNEAL ABRASIONS. SKIN : PARTICLES OF MAGNESIUM
    EMBEDDED IN THE SKIN MAY PRODUCE LESSIONS THAT RESIST HEALING.
    INGESTION: NO PROBLEM BECAUSE OF PHYSICAL PROPERTIES.
Explanation of Carcinogenicity:NO DATA PROVIDED BY MANUFACTURER
Effects of Overexposure:EXPOSURE TO MAGNESIUM METAL OR OXIDE DUST
    SHOULD BE A LOW HEALTH RISK BY INHALATION AND SHOULD BE TREATED AS
    A NUISANCE DUST. EXPOSURE TO MAGNESIUM OXIDE FUME AND SUBSEQUENT
    BURNING CAN RESULT IN META L FUME FEVER. THE TEMPORARY SYMPTOMS
    CANINCLUDE FEVER, CHILLS, NAUSEA, VOMITING AND MUSCULAR PAIN. ONSET
    OF SYMPTOMS OCCURS 4-12 HOURS AFTER EXPOSURE. EYES: MAY CAUSE BURNS
    AND CORNEAL ABRASIONS. SKIN : PARTICLES OF MAGNESIUM EMBEDDED IN
    THE SKIN MAY PRODUCE LESSIONS THAT RESIST HEALING. INGESTION: NO
    PROBLEM BECAUSE OF PHYSICAL PROPERTIES.
Medical Cond Aggravated by Exposure:NO DATA PROVIDED BY MANUFACTURER.

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

First Aid:EYE CONTACT: DO NOT FLUSH WITH WATER. REMOVE PARTICALS WITH
    COTTON TIP APPLICATOR. CORNEAL ABRASIONS ARE A POSSIBILITY. GET
    IMMEDIATE MEDICAL ATTENTION. INHALATION: REMOVE TO FRESH AIR. IF
    ILL EFFECTS  DEVELOP, GET MEDICAL ATTENTION.  SKIN: FLUSH
    THOROUGHLY WITH WATER, NO EFFECT EXPECTED.	INGESTION: IF
    SWALLOWED, IF CONSCIOUS, INDUCE VOMITING AND CALL A PHYSICIAN.

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

Flash Point:=635.C, 1175.F
Autoignition Temp:=510.C, 950.F
Extinguishing Media:SMOTHER WITH DRY GRAPHITE, TALC, DRY SAND, G-1
    POWDER, PURPLE-K. DO NOT USE WATER. DO NOT USE FOAM, HYDROGENATED
    EXTINGUISHING AGENTS OR CARBON DIOXIDE.
Fire Fighting Procedures:DON'T USE FOAM, CARBON TETRACHLORIDE, OR
    CARBON DIOXIDE. MANUAL APPLICATION OF WATER SHOULD BE CONDUCTED
    WITH CARE TO PREVENT CONTACT WITH BURNING/MOLTEN MATERIAL. PROTECT
    EYES & SKIN AGAINST FLYING P ARTICLES. AVOID DIRECT VIEWING OF
    MAGNESIUM FIRES. FIREFIGHTERS SHOULD WEAR A NIOSH-APPROVED SCBA &
    PROTECTIVE CLOTHING.
Unusual Fire/Explosion Hazard:COMBUSTIBLE MEATAL. EASILY IGNITED AND
    BURNS WITH INTENSE HEAT AND BRILLANT WHITE FLAME. POWDERS FORM
    EXPLOSIVE MIXTURE WITH AIR WHICH MAY BE IGNITED BY SPARK. IN FINELY
    DIVIDED FORM, WILL REACT WITH  WATER AND ACIDS TO RELEASE HYDROGEN.

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

Spill Release Procedures:RECOVER FOR USE IF NOT CONTAMINATED. DO NOT
    USE WATER TO CLEAN UP SPILL. USE APPROPRIATE SAFETY EQUIPMENT-CLEAN
    UP USING NON-SPARKING TOOLS-NO SMOKING OR OPEN FLAMES IN THE AREA.
