Hazards and Protection.
Separate from air, water, halocarbons, alcohols store in a cool, dry, well-ventilated location. Outside or detached storage is preferred. Inside storage should be in a standard flammable liquid storage warehouse, room, or cabinet. Aluminum alkyls 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. Aluminum alkyls in general, toxic materials or that can decompose into toxic components should be stored in cool ventilated place, out of sun, away from fire hazard. Substance must be periodically inspected and monitored. Incompatible materials should be isolated.
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.
Full protective clothing, preferably of aluminized glass cloth; goggles, face shield, gloves wear all purpose canister or self-contained breathing apparatus. 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).
Do not use water. Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Keep material dry.
Less sensitive to oxidation in air than trialkylaluminums aluminum alkyls.
Incompatible with acids and bases Incompatible with oxidizing agents.
When heated to decomposition, it emits acrid smoke and irritating fumes. Decomposition begins at 350 F, releasing alkenes and aluminum by-products.
Do not extinguish fire unless flow can be stopped. Do not use water. Use graphite, soda ash or powdered sodium chloride. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Ignites spontaneously in air reacts violently with water to form. Flammable ethane gas. Decomposition begins at 350 F (177 C), releasing alkenes and aluminum by-products. Aluminum alkyls 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. Aluminum alkyls pyrophoric material in flammable solvent. Vapors are heavier than air and may travel to a source of ignition and flash back. Aluminum alkyls
Contact with water from adjacent fires will cause formation of irritating smoke containing aluminum oxide and hydrogen chloride.
Intense smoke may cause metal-fume fever.
OSHA: PEL (8 h TWA): 15 mg/m3.
Shock, rapid breathing and pulse, circulatory collapse and other changes to pulse, blood pressure, and respirations may occur. Headache, myalgias, weakness, and paresthesias in both feet have been reported. Fetotoxicity, developmental abnormalities, and possible resistance to hydrogen chloride by inhalation during pregnancy have been noted. <br>No data were available on the possible effects of hydrogen chloride exposure during lactation. <br>No information about possible male reproductive effects was found in available references.
Gastritis, burns, gastric hemorrhage, dilation, edema, necrosis, and strictures may occur.
Changes in breathing pattern, irritation, changes in pulmonary function, corrosion and edema of the respiratory tract, chronic bronchitis and noncardiogenic pulmonary edema have been observed.
Burns, ulceration, scarring, blanching, and irritation may occur.
Dental discoloration or erosion, bleeding gums, corneal necrosis, inflammation of the eye, eye and nasal irritation, nasal ulceration, nose bleeds, throat irritation and ulceration have been observed.
The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
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 clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. Treat dermal irritation or burns with standard topical therapy. Patients developing dermal hypersensitivity reactions may require treatment with systemic or topical corticosteroids or antihistamines.
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
