SECTION 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW: Aluminum alloys in their solid state present no inhalation, ingestion or contact health hazard. However, inhaling dusts,
fumes or mists which may be generated during certain manufacturing procedures (melting, welding, sawing. brazing. grinding and machining) may be
hazardous to your health. Particulates / dusts may also be irritating to the unprotected skin or eyes.
ACUTE EFFECTS: Excessive exposure to dusts / fumes may cause irritation of eyes, nose or throat. Inhalation of dusts / fumes may result in metal
fume fever (metallic taste in mouth, dryness and irritation of throat, chills and fever).
CHRONIC EFFECTS: Prolonged inhalation of fumes or dusts may cause a variety of adverse health effects to the respiratory system, including (but not
necessarily limited to) lesions of the mucous membrane, bronchitis, pneumonia and cancers fo the nasal cavity and respiratory tract.
POTENTIAL HEALTH EFFECTS/MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
Any pre-existing chronic respiratory condition (asthma, chronic bronchitis, emphysema).
ROUTES OF ENTRY: Inhalation (dusts / fumes / mists), Contact with Skin and Eyes (dusts / mists), Ingestion (dusts).
SECTION 4 - FIRST AID MEASURES
INHALATION: Immediately remove victim to fresh air. If condition persists, consult physician.
EYE CONTACT: Immediatly flush with running water to remove particulates, consult physician.
SKIN CONTACT: If irritation develops, remove clothing and wash with soap and water. If condition persists, consult physician.
INGESTION: Consult physician.
NOTE TO PHYSICIAN: None.
SECTION 5 - FIRE FIGHTING MEASURES
FLASH POINT: Nonflammable at low temperatures, but will burn at high temperatures.
SPECIAL FIRE FIGHTING INSTRUCTIONS AND EQUIPMENT: None required.
AUTOIGNITION TEMPERATURE: NA
FLAMMABLE LIMITS: Nonflammable.
EXTINGUISHING MEDIA: Do not use water. Use carbon dioxide or dry chemical extinguishing agents.
