Hazards and Protection.
Protect against physical damage. Storage should be isolated; outside or detached storage is preferable. Separate from combustible or reactive materials. Inside storage should be in a standard flammable liquid storage room or cabinet. Alkylaluminums aluminum alkyls. In undiluted condition. Must be kept under inert gas like nitrogen or argon, and all possibility of contact with water must be avoided. Solution containing not more than 20% of these compd in non-reactive solvents, however, can be handled without risk of spontaneous ignition.
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.
Protective clothing & high standard of training in necessary precautionary measures are essential for handling of materials. Aluminum alkyls.
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.
Less sensitive to oxidation in air than trialkylaluminums aluminum alkyls.
Strong oxidizing agents.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.
Alkylaluminums decompose at temperatures above 350 to 450 F to form corresponding flammable, unsaturated hydrocarbon gases (ethylene, propylene and butylene). Alkylaluminums certain polymerization catalysts, such as aluminum alkyls, react and burn violently on contact with water. Aluminum alkyls aluminum alkyls are organic aluminum compounds that are highly reactive and dangerous because of spontaneous burning in air. Ignite spontaneously on exposure to air. React violently with water, oxidizing agents, halogenated hydrocarbons, alcohols and other compounds containing oxygen in their structure. Decompose at temperatures above 350 deg to 450 F to form the corresponding flammable, unsaturated hydrocarbon gases (ethylene, propylene and butylene).
OSHA: PEL (8 h TWA): 15 mg/m3.
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.
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.
Home irrigation - exposed eyes should be irrigated with copious amounts of water for at least 30 minutes. An examination should always be performed. Ophthalmologic consultation should be obtained. Medical facility: irrigate with sterile 0.9% Saline for at least an hour or until the cul-de-sacs are free of particulate matter and returned to neutrality (confirm with pH paper).
