Safety information
DOT Label：
Corrosive
First Aid：
SKIN: Remove contaminated clothing and shoes. Flush with copious amounts of water. (USCG, 1999)
Treatment：
EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.
Fire Hazards：
Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
Interactions：
Four cultivars of ryegrass (Lolium multiflorum Lam. cvs. Gulf, Marshall, Urbana, and Wilo) were grown in nutrient solution (pH 4.2 at 0 and 74 uM aluminum). Following a 30 min equilibration period after seeds were exposed to aluminum on day 10 after germination, total and monomeric aluminum concn were 78 + or - 6 and 69 + or - 5 um, respectively. Cations were desorbed from the Donnan free space of roots of 15, 23, and 35 day old plants using barium chloride, barium chloride triethanolamine, ammonium acetate, and potassium chloride. (The ability of desorbents to displace cations varied widely for the desorbent effect). Barium chloride triethanolamine showed the greatest ability to displace aluminum cations from the Donnan free space, while NH4+ did not displace detectable amounts of alum...
Safe Storage：
Separated from bases and strong oxidants. Dry. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.
Fire Fighting：

Fire Potential：
Prophoric material in flammable solvent. Vapors are heavier than air & may travel to a source of ignition & flash back. /Aluminum alkyls/
Health Effects：
Aluminum targets the nervous system and causes decreased nervous system performance and is associated with altered function of the blood-brain barrier. The accumulation of aluminum in the body may cause bone or brain diseases. High levels of aluminum have been linked to Alzheimer's disease. A small percentage of people are allergic to aluminium and experience contact dermatitis, digestive disorders, vomiting or other symptoms upon contact or ingestion of products containing aluminium. (L739, L740)
Health Hazards：
Vapor irritates eyes, nose and respiratory tract due to formation of sulfuric acid. Ingestion of large doses causes gastric irritation, nausea, vomiting, and purging. Liquid irritates eyes and skin. (USCG, 1999)

The proile summarizes data on organic and inorganic substances containing aluminum as the only metal. Each summary presents data on known and suspected health effects, the extent of worker exposure, physical and chemical properties and the industrial importance of the following aluminum compounds: aluminum metal, aluminum ammonium sulfate, aluminum chlorhydrate, aluminum chloride anhydrous, aluminum chloride hydrous, aluminum distearate, aluminum ethoxide, aluminum fluoride, aluminum...
Disposal Methods：
Aluminum sulfate: Pretreatment involves hydrolysis, followed by neutralization with sodium hydroxide.
FDA Requirements：
Drug products containing certain active ingredients offered over-the-counter (OTC) for certain uses. A number of active ingredients have been present in OTC drug products for various uses, as described below. However, based on evidence currently available, there are inadequate data to establish general recognition of the safety and effectiveness of these ingredients for the specified uses: aluminum sulfate is included in antiperspirant and topical antifungal drug products.
Toxicity Summary：
The main target organs of aluminum are the central nervous system and bone. Aluminum binds with dietary phosphorus and impairs gastrointestinal absorption of phosphorus. The decreased phosphate body burden results in osteomalacia (softening of the bones due to defective bone mineralization) and rickets. Aluminum's neurotoxicity is believed to involve several mechanisms. Changes in cytoskeletal protein functions as a results of altered phosphorylation, proteolysis, transport, and synthesis are believed to be one cause. Aluminum may induce neurobehavioral effects by affecting permeability of the blood-brain barrier, cholinergic activity, signal transduction pathways, lipid peroxidation, and impair neuronal glutamate nitric oxide-cyclic GMP pathway, as well as interfere with metabolism of...
Reactivity Alerts：
Water-Reactive
Spillage Disposal：
