Section 2 Physical Data:
Boiling Point: 4442°F
Specific Gravity: 2.7
Solubility in water: Insoluble in water
Appearance and Odor: Solid under normal conditions, Silvery ductile metal with no odor.

Section 3 Hazardous Ingredients Data:

Base metal, alloying elements: and metallic coatings	% Composition by weight (1)	ACGIH TLV (mg/m3) (2)
Aluminum	100.0	10 mg/m3
Alloying Elements:
Silicon	12.0	10 mg/m3

(1) % Alloying material varies with grade of material.
(2) 1985-1986 ACGIH threshold limit value

Section 4 Fire and Explosion Hazard Data:
Fire and Explosion Hazards: Unless otherwise noted, none. Product is a solid metal.
Fire Extinguishing Media: Do not use water. Use suitable dry powders or sand.
Special Fire Fighting Procedures: Use fire fighting methods and materials that are appropriate for surrounding fire.
Unusual Fire and Explosion Hazards: Dust or powder aluminum forms explosive mixtures in air. Bulk dust when damp may heat spontaneously. Hazard greater as fineness increases. Reacts with some acids and caustic solutions to produce hydrogen.

Section 5 Health Hazard Data:
Routes of Entry: Inhalation, ingestion and skin contact.
Effects of Overexposure: Metal dust and oxide is generally considered a "nuisance" particulate. May cause irritation of eyes, nose, and throat in excessive concentrations.
Acute Health Effects: Aluminum is not generally regarded as an industrial poison.
Chronic Health Effects: Inhalation of finely divided aluminum powder has been reported as a cause of pulmonary fibrosis.
Medical Conditions Aggravated by Exposure: May be implicated in Alzheimers disease.

Section 6 Emergency First Aid Procedures:
Inhalation: Remove to fresh air. Get medical attention.
Eye (s): Flush well with running water. Get medical attention.
Skin: Wash with soap and water.
Ingestion: Seek medical attention.

Section 7 Reactivity Data:
Stability: Stable.
Incompatibilities (materials to avoid): Halocarbons, Hg(amalgam) C12, I, (Fe + SiO2 + Al), (Al foil + Hg), (Al + Ba NO3 + KNO3+ S + organic material can explode).
Conditions to Avoid: None
Hazardous Decomposition Products: Reaction with water at high temperature and acids may emit H2. Nitric acid in some mixtures may emit Nitrogen Oxide.

Section 8 Protective Equipment:
Ventilation: If your process causes a release of dust or fume, use local and general exhaust ventilation to keep airborne concentrations of dust of fumes below the TLV.
Respiratory: If your process causes a release of dust or fume in excess of the permissible exposure limit, NIOSH approved respirators for protection against airborne dust or fumes should be worn. Respirators should be used in accordance with 29 CFR 1910.134.
Eyes: If your process involves grinding or any other action that causes the release of dust or fumes, approved safety glasses or goggles should be worn.
Skin: Gloves and barrier creams may be necessary to prevent skin sensitization and dermatitis.
Other: Avoid wearing contact lens if working around dust or powders.
Other Engineering Controls: Use special vacuum cleaners and dust collectors with high efficiency filters to collect dust or powders.
Work Practices: Operations which generate dust or powder should be done inside a fume hood or process enclosure.
Hygienic Practices: Wash thoroughly after handling and before eating, drinking, or smoking.

Section 9 Spill or Leak Procedures:
Product is a solid metal as shipped. No potential for spill or leak

Section 10 Waste Disposal:
Dispose of in accordance with local, state and federal regulations. In case material is released or spilled - Use normal housekeeping procedures. Avoid flames and sparks if fine aluminum powder is being cleaned up.

Section 11 Special Precautions:
Handling and storing: Fine powders should be treated as a flammable solid. Keep dry and isolate from the "materials to avoid" . Separate from oxidizing materials (see Section 7). Avoid storage near combustible materials.
Maintenance Personnel: Should follow same "hygienic practices" (see Section 8).
Other Precautions: Use with adequate ventilation, protection and good general hygiene.
