Odour Threshold:
Odourless (30)

Warning Properties:
NONE - aluminum sulfate is odourless.

Composition/Purity:
The main impurity is ferric oxide. Aluminum sulfate is commercially available as the anhydrous salt (Al2(SO4)3) (CAS 10043-01-3), the octadecahydrate (Al2(SO4)3.18H2O) (CAS 7784-31-8), tetradecahydrate (Al2(SO4)3.14H2O) (CAS 16828-12-9) and the hexadecahydrate (Al2(SO4)3.16H2O) (CAS 16828-11-8). Several other hydrated forms are also commercially available, however there is very little specific information available for these compounds. This review presents information for solid anhydrous aluminum sulfate. For information on the octadecahydrate, refer to CHEMINFO review of aluminum sulfate octadecahydrate. Information in the octadecahydrate record may also be applicable to the other hydrated forms. Aluminum sulfate, in various chemical forms, is also available as a solution in water (typically 33-50% by weight). Some commercial aluminum sulfate solutions contain excess sulfuric acid. This record does not apply to aluminum sulfate solutions. For information on solutions, consult your material safety data sheet or contact the manufacturer/supplier for advice. For additional information on sulfuric acid, refer to the CHEMINFO review of this chemical.

Uses and Occurrences:
Used mainly in the pulp and paper industry and as a flocculating agent or coagulant in water and waste treatment; for clarifying and/or purifying sewage and water; for clarifying fats, oils and petroleum products; as a leather tanning agent, a pH stabilizer, a cement hardening accelerator, a mordant in dyeing, an anticaking agent, a fire extinguisher, a flame retardant additive, and a foaming agent in firefighting foams; for wood and cellulose treatment; as a chemical intermediate for aluminum compounds; in the preparation of antiperspirants, agricultural pesticides, pigments and viscose rayon; as a catalyst, a fixing agent, and a food additive; for pickling of seeds and waterproofing concrete and cloth; as an absorbent for odour and gases; and in the decontamination of radiocontaminated metal surfaces.(14,30,32,33)


SECTION 3. HAZARDS IDENTIFICATION

EMERGENCY OVERVIEW:
Odourless, white lustrous to grayish white crystals, granules, pieces or powder. Hygroscopic. Will not burn. Can decompose at high temperatures forming corrosive and toxic sulfur dioxide and/or sulfur trioxide gases. EYE IRRITANT. Causes severe eye irritation. May be irritating to the skin, in the presence of moisture.



POTENTIAL HEALTH EFFECTS

Effects of Short-Term (Acute) Exposure

Inhalation:
Dusts of anhydrous aluminum sulfate probably cause varying degrees of irritation of the nose and throat, based on pH. The dust becomes acidic following contact with moisture in the air or respiratory tract tissues. Anhydrous aluminum sulfate does not form a vapour. There is no human information available.

Skin Contact:
The dust becomes acidic following contact with moisture on the skin and mild irritation may result. However, no irritation was observed in animal studies with aluminum sulfate. There is no human information available.
It has generally been considered that aluminum is very poorly absorbed through the skin.(1) Animal toxicity values for another water soluble aluminum salt indicates that toxic effects would not be expected following short-term skin contact.

Eye Contact:
Aluminum sulfate anhydrous is a severe eye irritant based on animal information. The dust becomes acidic following contact with moisture in the eye and moderate to severe irritation can result. One report, which provides no details about the type of exposure, indicates that a case of corneal injury has occurred following occupational exposure to aluminum sulfate (form and concentration unspecified). Healing occurred within 48 hours.(2)

Ingestion:
Ingestion of large amounts can probably cause irritation of the lining of the stomach. There is no human or animal information available. Ingestion is not a typical route of occupational exposure.

Effects of Long-Term (Chronic) Exposure

Nervous System:
A link between exposure to aluminum or aluminum compounds and Alzheimer's disease or other neurological diseases has been suggested. This link was suggested because of severe neurological effects which have been observed in patients receiving dialysis treatment (with dialysis fluids containing aluminum); effects seen in animals exposed to aluminum using non-occupational routes of exposure; case reports of neurological effects in individual workers; and findings of elevated aluminum levels in the brains of patients with neurological diseases. However, at present whether or not this association is a true effect is controversial and findings are inconsistent. Based on the available information, including studies of occupationally-exposed employees, recent reviewers have concluded that the evidence is inadequate to establish a link between occupational exposure to aluminum and specific effects on the nervous system or Alzheimer's disease, in normal, healthy workers.(1,5-9) One reviewer has concluded that there is a likely connection between long-term occupational exposure to aluminum and a specific effect, impaired co-ordination, but not other toxic effects on the nervous system or Alzheimer's disease.(10)

Lungs/Respiratory System:
No significant effects on the lungs or respiratory function and no significant increase in blood aluminum concentration were observed in 25 workers exposed to airborne concentrations of aluminum (as anhydrous aluminum sulfate or aluminum hydroxide) which were described as well below 3 mg/m3 for several years.(3)
Shortness of breath and wheezing at night, associated with an increased non- specific bronchial reactivity, was observed in 3 workers exposed to airborne anhydrous aluminum sulfate dust. The authors speculate that this effect was related to inhalation of the dust.(4) No firm conclusions can be drawn based on this single case report.

Skin:
Prolonged or repeated contact with dust or irritating solutions may cause redness, dryness and itching of the skin (dermatitis).

INGESTION: Ingestion of large amounts of aluminum salts over a prolonged period may cause phosphate deficiency, based on animal and human information.(11) Prolonged ingestion of high doses (several grams per day) may result in osteomalacia (softening and bending of the bones).(12) There are no reports of these effects from occupational exposures to aluminum salts.

Carcinogenicity:

There is no animal or human information available for anhydrous aluminum sulfate. Negative results have been obtained for other aluminum salts in animal studies.(13)

The International Agency for Research on Cancer (IARC) has not evaluated the carcinogenicity of this chemical.

The American Conference of Governmental Industrial Hygienists (ACGIH) has not assigned a carcinogenicity designation to this chemical.

The US National Toxicology Program (NTP) has not listed this chemical in its report on carcinogens.

Teratogenicity and Embryotoxicity:
No conclusions can be drawn based on the limited animal information available. There is no human information available.

Reproductive Toxicity:
There is no human or animal information available.

Mutagenicity:
No reliable studies using live animal and no human studies were located. A positive result has been obtained in cultured human cells. Negative results have been obtained in cultured mammalian cells and bacterial tests.

Toxicologically Synergistic Materials:
There is no information available.

Potential for Accumulation:
Aluminum is absorbed only to a limited degree from either the gastrointestinal tract or the lungs, and is rapidly excreted in the urine. A certain amount of tissue uptake does occur and animal experiments have shown that it can accumulate in bone.(14,15) The degree of absorption of aluminum following ingestion has been shown to depend on the chemical form of the metal as well as the presence of other dietary constituents such as citrate, ascorbate and lactate.(16) Water solubility has not been found to be a good indicator of the degree of aluminum absorption for different aluminum compounds.(17)


SECTION 4. FIRST AID MEASURES

Inhalation:
If irritation occurs, remove source of contamination or have victim move to fresh air. If irritation persists, obtain medical attention immediately.

Skin Contact:
Immediately flush contaminated area with lukewarm, gently flowing water for at least 20 minutes, or until the chemical is removed. Under running water, remove contaminated clothing, shoes and leather goods (e.g. watchbands, belts). If irritation persists, repeat flushing and obtain medical advice. Completely decontaminate clothing, shoes and leather goods before re-use or discard.

Eye Contact:
Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for 20 minutes or until the chemical is removed, holding the eyelid(s) open. Take care not to rinse contaminated water into the unaffected eye or onto the face. If irritation persists, obtain medical attention immediately.

Ingestion:
If irritation or discomfort occur, obtain medical advice immediately.

First Aid Comments:
Consult a doctor and/or the nearest Poison Control Centre for all exposures except minor instances of inhalation or skin contact.
All first aid procedures should be periodically reviewed by a doctor familiar with the material and its conditions of use in the workplace.



SECTION 5. FIRE FIGHTING MEASURES

Flash Point:
Not combustible (will not burn).

Lower Flammable (Explosive) Limit (LFL/LEL):
Not applicable

Upper Flammable (Explosive) Limit (UFL/UEL):
Not applicable

Autoignition (Ignition) Temperature:
Not applicable

Sensitivity to Mechanical Impact:
Not sensitive. Stable metal.

Sensitivity to Static Charge:
Not applicable. Not combustible.

Combustion and Thermal Decomposition Products:
Forms aluminum oxide, sulfur dioxide and/or sulfur trioxide at temperatures variably reported as above 650 deg C (1200 deg F) or 760 deg C (1400 deg F).(30)

Fire Hazard Summary:
Aluminum sulfate does not burn or support combustion. Heating aluminum sulfate to high temperatures may produce corrosive and toxic sulfur dioxide and/or sulfur trioxide gases. Well-sealed containers may rupture violently when exposed to fire or excessive heat for sufficient time. Aluminum sulfate dissolves in water with the evolution of heat and readily reacts to form corrosive sulfuric acid. Sulfuric acid is corrosive to some metals and gives off flammable hydrogen gas.(30)

Extinguishing Media:
Does not burn. Use fire extinguishing agents suitable for materials which are burning. Water and foam should not be used on fires involving aluminum sulfate, because corrosive liquids containing sulfuric acid may be produced. However, if it is necessary to use these extinguishing agents, proceed with due caution. Water or foam are best used for large fires or fires involving aluminum sulfate so

Fire Fighting Instructions:
Evacuate area and fight fire from a safe distance. Approach fire from upwind to avoid hazardous vapours and toxic decomposition products.
Closed containers may rupture violently when exposed to the heat of the fire. If possible, isolate materials not yet involved in the fire, and move containers from the fire area if this can be done without risk, and protect personnel. Otherwise, fire-exposed containers or tanks should be cooled by application of water spray. Application should begin as soon as possible and should concentrate on any unwetted portions of the container. Take care not to get water inside container. Apply water from the side and from a safe distance until well after the fire is out. For a massive fire under these circumstances, it may be prudent to use unmanned hose holders or monitor nozzles. In any case, stay away from the ends of tanks involved in the fire.
The decomposition products of aluminum sulfate are corrosive and hazardous to health. Do not enter without wearing specialized protective equipment suitable for the situation. Firefighter's normal protective clothing (Bunker Gear) will not provide adequate protection. Chemical resistant clothing (e.g. chemical splash suit) and positive pressure self-contained breathing apparatus (MSHA/NIOSH approved or equivalent) may be necessary.

SECTION 10. STABILITY AND REACTIVITY

Stability:
Normally stable. On exposure to air, anhydrous aluminum sulfate gradually absorbs moisture from the atmosphere. It reacts with water with the evolution of heat and forms corrosive sulfuric acid.(30)

Hazardous Polymerization:
Does not occur

Incompatibility - Materials to Avoid:

NOTE: Chemical reactions that could result in a hazardous situation (e.g. generation of flammable or toxic chemicals, fire or detonation) are listed here. Many of these reactions can be done safely if specific control measures (e.g. cooling of the reaction) are in place. Although not intended to be complete, an overview of important reactions involving common chemicals is provided to assist in the development of safe work practices.


WATER - forms sulfuric acid.(30)
STRONG OXIDIZING AGENTS (e.g. chlorine, perchlorates, peroxides) - reaction may be violent. May give off sulfur dioxide.(31)
STRONG BASES (e.g. sodium hydroxide) - may react violently.(30)

Hazardous Decomposition Products:
Sulfuric acid

Conditions to Avoid:
Generation of airborne dusts, moisture, high temperatures.

Corrosivity to Metals:
Dry aluminum sulfate is not corrosive to metals. In the presence of moisture, aluminum sulfate is corrosive to metals such as cast iron, steel, some types of stainless steel (12 Cr and 17 Cr) and aluminum at normal temperatures, and to brass at high temperatures. It is not corrosive to nickel-molybdenum, nickel-chromium-molybdenum and nickel-chromium-iron- molybdenum alloys, and to types 304, 316 and 20-25-4.5 stainless steels at normal temperatures.(35)


SECTION 11. TOXICOLOGICAL INFORMATION

LD50 (oral, rat): 1930 mg/kg (14, unconfirmed)
LD50 (oral, mouse): 980 mg Al/kg (cited as 0.98 g Al/kg, aluminum sulfate, form not specified) (19)
LD50 (oral, rat): greater than 9000 mg/kg (aluminum sulfate octadecahydrate); greater than 730 mg Al/kg (39)
LD50 (oral, mouse): greater than 9000 mg/kg (aluminum sulfate octadecahydrate); greater than 730 mg Al/kg (39)

Eye Irritation:

Application of 10 mg of aluminum sulfate hydrate produced severe eye irritation in rabbits. Corneal opacity, erythema, chemosis and discharge persisted until day 7 in some animals. Further follow-up was not reported.(38)

Skin Irritation:

No evidence of irritation was observed following application of a solution of 10% aluminum sulfate (form unspecified) in water (pH 3.0) to mice, rabbits and guinea pigs for 5 days.(20) Aluminum sulfate hydrate was applied to the skin of rabbits for 4 hours. No irritation was observed (scored 0) at 4 hours, 24 hours and 48 hours.(38)

Effects of Long-Term (Chronic) Exposure:

Inhalation:
Effects on respiratory function were observed in rats, but not in guinea pigs, following inhalation of 2.59 mg/m3 anhydrous aluminum sulfate particles (mass median aerodynamic diameter 1.4 um respectively) for 8 weeks. Significantly reduced performance on a treadmill test was also observed in rats.(21) Reversibility of the respiratory effects was not assessed.

Ingestion:
In general, no harmful effects have been observed in various experimental animals following ingestion of fairly high doses (1-2%) of anhydrous aluminum sulfate in the diet (duration of studies unspecified). Decreased growth, disturbances of calcium and phosphorus metabolism, muscle weakness and death have been observed following ingestion of doses greater than 2%.(22)

Teratogenicity, Embryotoxicity and/or Fetotoxicity:
No conclusions can be drawn from one mouse study. An increase in the activity of a specific enzyme in the brain (choline aceyltransferase), but no effect on litter size, birth weight or behavioural or developmental test results, was observed in the offspring of mice fed 0.27 mg/day (approximately 13.5 mg/kg/day) anhydrous aluminum sulfate in drinking water for 8 days during pregnancy.(26) The significance of this observation is not known and no information concerning maternal toxicity was provided.

Mutagenicity:
Positive results (chromosomal aberrations in bone marrow cells) were obtained in 5 male rats following oral administration of up to 2120 mg/kg/day aluminum sulfate octadecahydrate for up to 21 days.(27) However, evidence of severe toxicity was observed in the animals (a dose-related suppression of bone marrow cell division). Therefore, no conclusions can be drawn from this study.
A solution of aluminum sulfate in water produced positive results in cultured human cells (leukocytes) (sister chromatid exchanges, micronuclei and chromosomal aberrations).(28) Negative results have been obtained in bacteria and cultured mammalian cells.(29)

NEUROLOGICAL EFFECTS: Positive and negative results have been obtained in behavioural tests administered to rats following ingestion of anhydrous aluminum sulfate or its octadecahydrate form. However, a clear pattern of cause and effect has not been established and it is not possible to draw firm conclusions from the limited data available. No harmful effects on learning ability, activity level or body weight were observed in rats following inhalation of 2.04 mg/m3 anhydrous aluminum sulfate (mass median aerodynamic diameter 2.0 um) for 7 weeks.(21) Possible evidence of effects on the brain (decreased time to reach extinction criteria on a passive avoidance task) were observed in rats following ingestion of 0.3% aluminum (as aluminum sulfate octadecahydrate) in drinking water for 30 days. There were no effects on physical activity level or another measure of learning (acquisition of the passive avoidance task).(23) Impairment in one test designed to measure effects on the brain (cognitive function), but not in 3 other tests, was observed in rats following ingestion of 3.7% aluminum sulfate octadecahydrate in drinking water for 30 days.(24) Adverse effects on nerve cells in the brain (degeneration) were observed in rats following ingestion of 265-2120 mg/kg/day octadecahydrate for up to 21 days.(25) The statistical significance o f these results was not evaluated and, therefore, it is not possible to draw any conclusions from this study.
