ABC of Safety in the Biological Sciences
ALUMINIUM HYDROXIDE Al(OH)3
Alumina hydrate, alumina trihydrate, hydrated alumina, aluminum hydroxide.
Odourless, white crystals, powder or granules.
Aluminium hydroxide is incompatible with chlorinated rubber at high temperatures (216°C). Avoid strong acids and strong bases.
HEALTH HAZARD DATA
There is little data available concerning the toxicity of this compound although it is known to be an eye and respiratory tract irritant. It is an abrasive and as such can cause skin and eye irritation. Recent studies in Britain have suggested that a link exists between ingestion of aluminium and senile dementia. Introduction of aluminium compounds directly into the bloodstream may contribute to the development of neurological effects resembling senility.
HANDLING and GENERAL PRECAUTIONS
Avoid eye contact.
Avoid inhalation of the powder.
Wash hands thoroughly after handling.
Cover open sores and cuts.
Wear protective clothing to avoid eye contact and inhalation. A long sleeved laboratory coat or gown, rubber gloves, safety goggles and a face mask as a minimum standard.
Skin wash the affected area with large amounts of water until all evidence of the chemical has been removed (approximately 15 minutes). If necessary seek medical attention.
Eyes immediately wash the affected eye with large amounts of water until all evidence of the chemical has been removed (approximately 15 minutes). If irritation persists seek medical attention.
Inhalation remove from the area of exposure to fresh air. If breathing has ceased apply artificial respiration, Keep warm and allow to rest. If irritation persists seek medical advice.
Ingestion the affects of ingestion are not known, therefore wash out the mouth thoroughly with water and seek immediate medical advice. DO NOT INDUCE VOMITING.
Store in a cool, dry atmosphere.
Wear rubber gloves, safety glasses and laboratory coat.
SPILLS: Solid - collect in a beaker, dissolve in a large amount of water. Add soda ash, mix and neutralise with 6M hydrochloric acid and if local laws allow, discharge to sewer with large excess of water.
Solution - cover with soda ash, mix and scoop into a beaker of water. Neutralise with 6M hydrochloric acid and if local laws allow, discharge to sewer with a large excess of water.
PACKAGE LOTS: Add slowly to a large container of water. Stir in a slight excess of soda ash. Let stand for 24 hours. Decant or siphon into another container and neutralise with 6M hydrochloric acid. If local laws allow, discharge to sewer with a large excess of water. The sludge may be added to land fill.
