Hazards and Protection.
Storage
Keep tightly closed in a cool place in a tightly closed container.
Handling
Containers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid), all hazard precautions given in the data sheet must be observed.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
ELIMINATE all ignition sources. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS.
Stability
Stable.
Incompatibilities
Reacts violently with acid and is corrosive to aluminium and zinc.

Fire.
Fire fighting
Extinguish using agent most appropriate for surrounding fire.
Fire potential
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Hazards
Contact with metals may evolve flammable hydrogen gas.
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.

Health.
Exposure limit(s)
TLV (as Al (soluble salts)): ppm; 2 mg/m3 (as TWA) (ACGIH 1992-1993).

Exposure effects
Encephalopathy has been reported in patients with renal failure. This may range from mild personality changes and speech disorders to severe obtundation, seizures, coma and death. Fatal encephalopathy with status epilepticus has occurred after the use of aluminum-containing bone cement in vestibular neurectomies. Aluminum has also been linked to the histopathology of alzheimer disease. Occupational exposure to aluminum has been associated with cognitive deficits. Aluminum in drinking water has been linked to central nervous system birth defects. Some aluminum compounds have proven teratogenic in laboratory animals; however, overall, aluminum is not considered teratogenic.
   Ingestion
Nausea, vomiting and diarrhea are possible if ingested.
   Inhalation
Cough, tachypnea, and wheezing are common after inhalation.
   Skin
Redness, swelling and pain may occur.
   Eyes
Irritants may cause swelling, redness and pain at any site, especially at mucous membranes. The mouth, nose, and eyes are susceptible to these effects.

First aid
 
   Ingestion
Seek medical assistance.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult.
   Skin
Most cases of aluminum related dermal reactions are due to chronic exposure.
   Eyes
Immediately flush with running water for at least 20 minutes.
