3.Hazard Identification

4.First Aid Measures

Inhalation:

Not considered to be a health hazard as supplied.  However, if dust or hot vapour is inhaled, move the exposed person to a well-ventilated area, rinse nose and mouth with water and provide rest and warmth.  If discomfort persists, consult a physician.

Ingestion:

Not relevant

Skin Contact:

Not considered to be a health hazard as supplied.  However, if hot metal comes into contact with skin, remove the affected person from source of contamination and rinse the skin with plenty of cold water.  If burn is severe, consult a physician.

Eye contact:

Dust in the Eyes – remove any contact lenses and flush eyes thoroughly with water, taking care to rinse under eyelids.  Continue flushing for at least 15 minutes.  If discomfort persists, consult a physician.

5.Fire Fighting Measures

Extinguishing Media:

Not a fire hazard unless in particulate form.  Suspensions of aluminium dust in air may pose a severe explosion hazard.  A potential for explosion exists for a mixture of fine and coarse particles if at least 15-20% of the material is finer than 44 microns (325 mesh).  Buffing and polishing generate finer material than grinding, sawing and cutting.  In case of aluminium fires, use a class D dry powder extinguisher.  Do NOT use water or halogenated extinguishing media.

Hazardous Combustion Products:

Not relevant

6.Accidental Release Procedures

7.Handling and Storage

Handling Precautions:

Because of the risk of explosion, aluminium alloy scrap must be thoroughly dried prior to remelting.
Hot aluminium does not exhibit any warning colour change.  Exercise great caution since the metal may be hot.  Use standard techniques to check metal temperature prior to handling.
Possibility of sharp edges – use protective gloves.

Storage Conditions:

Store in dry conditions away from any of the chemicals listed in Section 10.

10.Stability and Reactivity

Stability: Stable
Conditions to avoid: In the form of particles, aluminium may explode when mixed with halogenated acids, halogenated solvents, bromates, iodates or ammonium nitrate.  Aluminium particles on contact with copper, lead or iron oxides can react vigorously with release of heat if there is a source of ignition or intense heat.
Hazardous Decomposition: Aluminium, particularly in the form of particles, reacts with halogenated acids, water and caustic alkalis producing flammable hydrogen gas.

Yes

No

Acute Effects:

  • Solid aluminium does not present an inhalation hazard.
  • Aluminium & Silicon dusts generated during use are considered nuisance particles.
  • High concentrations of freshly – formed of copper, magnesium or zinc oxides can produce symptoms of metal fume fever.
  • High concentrations of copper dust can cause irritation of the upper respiratory tract.

Not applicable

Irritation through mechanical abrasion

Contact with hot metal can cause burns

Not applicable

Chronic Effects:
Ingestion and Inhalation:
High concentrations of manganese dust can affect the central nervous system (apathy, drowsiness, weakness and other symptoms resembling Parkinson’s disease.)
Medical Conditions Aggravated
By Exposure:Not determined
Carcinogenicity/Mutagenicity/
Reproductive Toxicity: Certain alloys of this series may contain chromium or nickel.

12.Ecological Information

Aluminium and its alloys under solid form do not present any hazard for the environment because metals are not biologically available.

13.Disposal Considerations

Recycle using appropriate precautions. Aluminium in the particulate form may be reactive, and its hazardous characteristics should be determined prior to disposal
