Aluminum compounds are treated under anhydrous conditions to prevent violent reactions, recover solvent, and form Al compounds suitable for landfill by reaction with anhydrous hydrolysis agent, eg calcium hydroxide. /Aluminum compounds/|SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

Anon; Information profiles on Potential Occupaional Hazards: Aluminum & Compounds, 2nd Draft (Revised); GRA & I Issue 21 NTIS/PB89-216238 (1989)> TD3: Information profiles are working papers used by the National Institute for Occupational Safety and Health to assist the Institute in establishing priorities. 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 hydride, aluminum hydroxide, aluminum nitrate, aluminum oxide, aluminum ortho-phosphate, aluminum potassium sulfate, aluminum silicate, aluminum sodium sulfate, aluminum sulfate, calcium aluminum silicate, diethylaluminum chloride, sodium aluminate, tri-n-butylaluminum, triethylaluminum, tri-n-hexylaluminum, triisobutylaluminum, tri-n-octylaluminum. Detailed literature searches are conducted to identify information to be used in the profile sumaries. Sponsored by National Inst. for Occupational Safety and Health, Rockville, MD.

Fight fire from protected location or maximum possible distance. DO NOT use water. Violent reaction may result. Use graphite powder, soda ash, or powdered sodium chloride to extinguish fire. On solvent based materials use dry chemical, foam, or carbon dioxide. Use water spray cautiously to keep fire-exposed containers cool.|Stop flow of liquid before extinguishing fire. Use dry chemical or carbon dioxide. DO NOT use water as straight stream directly on spilled material. Water fog can be used to control fire. DO NOT use halogenated extinguishing agents on spilled material. Violent reaction may result. Use water spray to keep fire-exposed containers cool. Fight fire from protected location or maximum possible distance. /Aluminum Alkyls/

Approach release from upwind. Keep water away from release. Do no use foam to blanket release or suppress vapors. Stop or control the leak, if this can be done without undue risk. control runoff and isolate discharged material for proper disposal.

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.|Work clothing that becomes wet or significantly contaminated should be removed and replaced. /Aluminum (soluble salts and alkyls, as Al)/|Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premises. /Aluminum (soluble salts and alkyls, as Al)/|The worker should immediately wash the skin when it becomes contaminated. /Aluminum (soluble salts and alkyls, as Al)/|SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
