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/

Extremely reactive with air, moisture and compounds containing active hydrogen and therefore must be kept under a blanket of inert gas. /Aluminum alkyls/

All possibility of contact with water must be avoided. Solution containing not more than 20% of these compounds in non-reactive solvents, however, can be handled without risk of spontaneous ignition. /Aluminum alkyls/

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 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.

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.

In the gut, antacids form insoluble compounds with numerous substances. Interactions are especially prominent with aluminum-containing antacids. Aluminum forms insoluble aluminum phosphate, which decreases the bioavailability of phosphate. Although aluminum fluoride is somewhat soluble, aluminum-containing antacids interfere with the absorption of fluoride, probably through the formation of more complex compounds, such as fluoroapatite. Aluminum-containing antacids adsorb bile acids, lysolecithin, and various proteins. /Aluminum-Containing antacids/

/SIGNS AND SYMPTOMS/ /Anhydrous aluminum fluoride is a/ strong irritant to tissue.

/SIGNS AND SYMPTOMS/ Symptoms Following Exposure /to aluminum fluoride/: Acute: respiratory irritation, possible nose bleeding or vomiting: Chronic: aggravates bronchitis/ asthma; increased bone density.

/SIGNS AND SYMPTOMS/ Fluorosis. Inhalation of fluoride poses a potential hazard in workers in primary aluminium production, but the majority of workers are clinically unaffected. Clinical fluorosis, which is rare, commences with stiffness in the lower back followed by pain and then limitation of rotation of the trunk. Later, the spine becomes rigid and stiff, with restriction of chest movement and of the large joints, particularly the hip, that is accompanied by osteosclerosis. /Aluminum fluorides/

/SIGNS AND SYMPTOMS/ Variable degrees of bony fluorosis have been seen. The first stage of this condition consists simply of an increase in bone density, particularly marked in the vertebral bodies and pelvis. As fluoride is further absorbed into bone, calcification of the ligaments of the pelvis may be seen ... In the event of extreme and protracted exposure to fluoride, calcification of the paraspinal and other ligamentous structures as well as about joints are noted. /Aluminum fluorides/

/LABORATORY ANIMALS: Acute Exposure/ /Acute poisoning/ if sufficient fluoride is absorbed ... Fluoride ion increases capillary permeability and also produces a coagulation defect. These actions lead to hemorrhagic gastroenteritis and hemorrhages, congestion, and edema in various organs including the brain. Clinical manifestations include excitability, muscle tremors, weakness, urination, defecation, salivation, emesis, sudden collapse, clonic convulsions, coma, and death due to respiratory and cardiac failure. Cyanosis and early rigor mortis ... /Fluoride/

/LABORATORY ANIMALS: Acute Exposure/ After intraperitoneal administration of a single large dose of fluoride (sodium fluoride, 35 mg/kg body weight), the calcium contents of the renal cortex and medulla of fluoride intoxicated rats were increased by 33 and 10 times, respectively. /Sodium Fluoride/

/LABORATORY ANIMALS: Acute Exposure/ The ionic fluoride levels in plasma following intraperitoneal administration of 15, 20, or 25 mg of fluoride per kg body weight to 200 g rats /was studied/. In animals given 25 mg/kg, the mean ionic fluoride level in plasma was 38 mg/liter after 10 min and the animals invariably died within 1 hr. All animals receiving 15 or 20 mg/kg survived, despite mean ionic fluoride levels in plasma of 22.9 and 29.2 mg/l, respectively. /Sodium Fluoride/

/LABORATORY ANIMALS: Acute Exposure/ The acute and subacute physiological and pathological effects of fluoride (as sodium fluoride) administered intravenously and orally to male and female dogs /were described/. When fluoride was infused intravenously in four dogs at the rate of 5.4 mg Fluoride/min, the mean acute lethal dose was 36.0 + or - 0.5 mg Fluoride/kg with death occurring after 59 to 64 minutes of infusion. The principal effects observed were a progressive decline in blood pressure, heart rate, central nervous system activity (pupil size, response to light, tendon reflexes) with vomiting and defecation. /Sodium Fluoride/

Chronic fluorosis generally develops after prolonged (10-20 years) exposure to industrial dusts, insecticides, or water where fluorides exceed 3 to 4 ppm. This is especially true in workers involved in the production of aluminum, steel, or glass. /Aluminum fluorides/

Production of aluminum sulfate and aluminum fluoride is associated with exposure to several irritant substances. Such production has been connected with reversible bronchial obstruction or asthma. In an aluminum plant in Sweden, 6 cases of asthma occurred in 1975, and 7 in 1976. The number of exposed workers was 35-40. The levels of aluminum fluoride (personal sampling) were measured during these two years, and the mean concentrations were 3-6 mg/cu m. In 1977, improvements were made at this plant thereby reducing the mean levels of aluminum fluoride to 0.4-1.0 mg/cu m. During the years 1978-1980, only two cases of asthma occurred. /Aluminum fluorides/

Electrolytic production of aluminum can lead to a substantial exposure to fluorides and carcinogenic tar oils, including polyaromatic hydrocarbons. /Aluminum fluorides/

Primary aluminum production plants are located in about 40 countries. The two main methods used for aluminum production are Soderberg and prebake, which encompass a number of processes and job categories. Substantial exposures to airborne polynuclear aromatic compounds have been measured in certain occupational settings in this industry. Exposures have been higher in potrooms of plants using the Soderberg process than in those using the prebake process; some workers may have exposed to both process. Exposures to fluorides and a variety of other contaminants also occur in potrooms. /Aluminum fluorides/
