HEALTH HAZARD DATA
Eye and skin irritant. Prolonged exposure to the dust can cause upper respiratory tract irritation. TLV (Worksafe Australia) 10mg/m3.
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 (approximately 15 minutes). If irritation persists seek medical advice.
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 or pain persists 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 advice.
Ingestion - Never give anything by mouth if the victim is losing consciousness, is unconscious or convulsing. Rinse the mouth thoroughly with water. Induce vomiting using Ipecac syrup. Seek medical advice.
Absorbs atmospheric moisture, keep lid tightly closed. Store in a cool, dry atmosphere away from heat and incompatible substances.
Wear protective clothing. A long sleeved laboratory coat or gown with elasticised wrist bands, rubber gloves and safety goggles as a minimum standard.
Dispose of by high temperature incineration.
The environmental effects of this compound have not been studied. Boric oxide will hydrolyse slowly in aqueous solution to form boric acid. This chemical has a low potential to effect aquatic organisms but may have a moderate potential to cause effects on secondary waste treatment plants. A moderate quantity of boric oxide released into the environment is not expected to have a significant adverse impact.
