|Hazards and Protection.|
Must be completely sealed off from atmosphere.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear safety goggles, face shield, gas mask and protective rubber clothing. Protective clothing and high standard of training in necessary precautionary measures are essential for handling of materials.
Wear positive pressure self-contained breathing apparatus (SCBA).
Use a fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire. ELIMINATE all ignition sources and prevent all contact with spilled material. Stop leak if you can do it without risk. Cover with DRY earth, DRY sand, or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain. Use clean non-sparking tools to collect material and place it into loosley covered plastic containers for later disposal.
Explodes violently in water. Violent reactions can occur if exposed to halogenated hydrocarbons. Highly reactive.
Reacts violently with water, alcohols, phenols, amines, carbon dioxide, sulfur oxides, nitrogen oxides, halogens, and halogenated hydrocarbons, causing fire and explosion hazards.
Decomposition to Al(OH)3 + C2H6 when heated to decomposition, it emits acrid smoke and irritating fumes.
Corrosive to living tissue.
Fire Extinguishing Agents Not to Be Used: Water, foam, halogenated extinguishing agents.Fire Extinguishing Agents: Inert powders (sand, limestone), dry chemical
Extreme. Very flammable. Ignites spontaneously in air.
May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. May react vigorously or explosively on contact with water. May decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished.
Intense smoke may cause metal-fume fever.

|Exposure effects||Headache, myalgias, weakness, and paresthesias in both feet have been reported. Aluminum in drinking water has been linked to central nervous system birth defects. Some aluminum compounds have proven teratogenic in laboratory animals; however, overall, aluminum is not considered teratogenic.|
Burns of the esophagus and less commonly the stomach may occur after caustic ingestion; the absence of oral mucosal injury does not reliably exclude esophageal burns. Patients with stridor, drooling or vomiting are more likely to have esophageal burns.
Stridor, dyspnea, upper airway injury, and pulmonary edema, especially following inhalation of vaporized caustics, may occur.
Severe skin irritation and/or burns may occur.
|First aid|| |
Mucosal if no respiratory compromise is present, dilute immediately with milk or water; no more than 8 ounces in adults and 4 ounces in children. Gastric ipecac contraindicated. Consider insertion of a small, flexible nasogastric or orogastric tube to suction gastric contents after recent large ingestions; the risk of further mucosal injury must be weighed against potential benefits.
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
Remove contaminated clothes. Irrigate exposed skin with copious amounts of water for at least 15 minutes or longer, depending on concentration, amount and duration of exposure to the chemical. A physician may need to examine the area if irritation or pain persist.
