Fraction By Weight: BAL.

Routes of Entry: Inhalation:YES Skin:YES Ingestion:YES
Health Hazards Acute and Chronic:EYE: MECHANICAL HAZARD. SKIN CONTACT:
MECHANICAL HAZARD. SKIN ABSORPTION: UNLIKELY. INGESTION: UNLIKELY.
INGESTION OF LARGE AMOUNTS OF DUST COULD CAUSE SERIOUS INJURY, EVEN
DEATH, BECAUSE ACUTE ORAL T OXICITY OF MAGNESIUM IS MODERATE.
INHALAITON: DUST MAY CAUSE IRRITATION TO RESPIRATORY TRACT.
SYSTEMIC AND OTHER EFFECTS-EXPOSURES INCIDENTAL TO INDUSTRIAL
HANDLING ARE NOT ANTICIPATED TO CAUSE ADVERS E EFFECTS. REPEATED
EXCESSIVE EXPOSURE TO FUMES OR DUST OF A NUMBER OF METALS,
INCLUDING ALUMINUM. MAY CAUSE CENTRAL NERVOUS SYSTEM AND
DEVELOPMENTAL EFFECTS.
Effects of Overexposure:EYE: MECHANICAL HAZARD. SKIN CONTACT:
MECHANICAL HAZARD. INGESTION: SERIOUS INJURY, EVEN DEATH.
INHALATION: DUST IRRITATION TO RESPIRATORY TRACT, SYSTEMIC AND
OTHER EFFECTS. REPEATED EXCESSIVE EXPOSUR E TO FUMES OR DUST OF A
NUMBER OF METALS, INCLUDING ALUMINUM. MAY CAUSE CENTRAL NERVOUS
SYSTEM AND DEVELOPMENTAL EFFECTS.

First Aid:EYES: IRRIGATE IMMEDIATELY WITH WATERFOR AT LEAST 5 MINUTES.
SKIN: WASH OFF DUST IN FLOWING WATER OR SHOWER. INGESTION: INDUCE
VOMITING IF LARGE AMOUNTS OF DUST ARE INGESTED. CONSULT PHYSICIAN.
INHALA TIONS: REMOVE TO FRESH AIR IF DUST INHALATION> CALL
PHYSICIAN. NOTE TO PHYSICIAN: NO SPECIFIC ANTIDOTE FOR DUST
INHALATION.

Extinguishing Media:SMOTHER BURNING MAGNESIUM BY CONVERING WITH
EXTINGUISHING POWDER APPROVED FOR USE ON MAGNESIUM FIRE (GI,
MET-L-X, ETC.). CONSULT NATIONAL FIRE PROTECTION ASSOC. FOR MORE
INFORMATION.
Fire Fighting Procedures:FIRE FIGHTING EQUIPMENT SHOULD INCLUDE WEARING
POSITIVE PRESSURE SELF-CONTAINED BREATHING APPARATUS.
Unusual Fire/Explosion Hazard:FIRE AND EXPLOSION HAZARDS WHEN HEATED IN
AIR TO TEMP NEAR ITS MELTING POINT, MAGNESIUM ALLOYS IGNITE AND
BURN WITH WHITE FLAME. WATER ON BURNING MAGNESIUM WILL PRODUCE
HYDROGEN GAS AND MAY CAUSE EXPL OSION.

Spill Release Procedures:CLEAN OFF AND USE.
