ABC of Safety in the Biological Sciences
ALUMINIUM OXIDE (Al2O3)
Occurs naturally as the mineral corundum.
SYNONYMS
Alumina, alumine, alumina, alpha-alumina, aluminum oxide,
aluminum trioxide, corundum.
CHARACTERISTICS
White, odourless, crystalline solid or powder.
INCOMPATIBILITY
Incompatible with:
Hot chlorinated rubber violent reaction.
Chlorine trifluoride violent reaction with flames.
Ethylene oxide violent polymerisation may occur.
HEALTH HAZARD DATA
This substance is an abrasive and is a skin, eye and mucous
membrane irritant. Skin and eye contact may cause localised
irritation and pain. Inhalation may cause irritation, coughing
and dyspnoea. Chronic exposure may in addition cause pulmonary
fibrosis, emphysema and pneumonia. Pneumothorax has been
reported in some workers and rarely, encephalopathy. Ingestion
may cause nausea, vomiting and weakness. 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 skin and eye contact.
Avoid inhalation or ingestion of the powder.
Wash hands thoroughly after handling.
Cover open sores and cuts.
Use a fume hood to minimise exposure to this substance. Wear
protective clothing to avoid skin or eye contact, inhalation or
ingestion. A long sleeved laboratory coat or gown, rubber
gloves, safety goggles and a face mask as a minimum standard.
TREATMENTS
Skin immediately wash the affected area with soap or mild
detergent and large amounts of water until all evidence of the
chemical has been removed. If hypersensitivity develops seek
medical attention.
Eyes wash the affected eye with large amounts of water until
all evidence of the chemical has been removed (approximately 15
minutes). If irritation or pain persist seek immediate medical
attention.
Inhalation remove from the area of exposure to fresh air. Keep
warm and allow to rest. If irritation persists seek medical
attention.
Ingestion wash out the mouth thoroughly with water and give
water to drink. DO NOT INDUCE VOMITING. Never give anything by
mouth to an unconscious person. Seek immediate medical advice.
STORAGE
Store in a cool, dry atmosphere away from incompatible
substances. Keep the lid tightly closed.
DISPOSAL
Wear heavy gloves and safety glasses. The waste may be used as
fill in reclaiming low areas or may be dumped in a landfill.
