Hazards and Protection.
Storage
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area.
Handling
Wash thoroughly after handling. Use with adequate ventilation. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid contact with heat, sparks and flame. Avoid ingestion and inhalation. Do not allow contact with water. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Protection
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Respirators
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Small spills/leaks
Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation. A vapor suppressing foam may be used to reduce vapors.
Stability
Stable under normal temperatures and pressures.
Incompatibilities
Oxidizing agents.
Decomposition
Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, aluminum oxide.

Fire.
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Dusts at sufficient concentrations can form explosive mixtures with air. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Will burn if involved in a fire. Water Reactive. Material will react with water and may release a flammable and/or toxic gas. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. Flammable solid. Extinguishing media: Use water spray to cool fire-exposed containers. Use carbon dioxide or dry chemical. DO NOT USE WATER! Do NOT get water inside containers. Do NOT use straight streams of water.
Fire potential
Flammable/combustible material. May be ignited by friction, heat, sparks or flames.
Combustion products
Fire may produce irritating and/or toxic gases.

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
May cause irritation of the digestive tract. May cause gastrointestinal irritation with nausea, vomiting and diarrhea. Hydrolyzes in the presence of water and body fluids to propan-2-ol, which can cause headache, nausea, narcosis, and mental depresssion.
   Inhalation
May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. Inhalation of dusts cause severe irritation of the upper respiratory tract, gastrointestinal disturbances, albuminuria, gradual loss of weight, and increasing weakness.
   Skin
May cause skin irritation. The toxicological properties of this material have not been fully investigated.
   Eyes
May cause eye irritation. The toxicological properties of this material have not been fully investigated.

First aid
 
   Ingestion
Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
   Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
   Skin
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists. Wash clothing before reuse.
   Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
