HEALTH HAZARD DATA
Sodium citrate is an eye and respiratory tract irritant and large quantities may cause abdominal discomfort and pain. It is mildly corrosive.
Skin immediately remove contaminated clothing and 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). Wash contaminated clothing before reuse.
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 persist 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 or develops seek medical attention.
Ingestion wash out the mouth thoroughly with water and give water or milk to drink. If discomfort or pain persist seek medical attention.
Store in a cool, dry atmosphere.
Wear protective clothing. A long sleeved laboratory coat or gown, rubber gloves, safety goggles and a face mask as a minimum standard.
Rubber gloves, safety glasses and laboratory coat.
Solid: collect in a beaker, dissolve in a large amount of water. Add soda ash, mix and neutralise with 6M hydrochloric acid and 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 discharge to sewer with a large excess of water. If a spill contains a fluoride, add slaked lime in addition to the above treatment.
Add slowly to a large container of water. Stir in a slight excess of soda ash. If fluoride is present add slaked lime. Let stand for 24 hours. Decant or siphon into another container and neutralise with 6M hydrochloric acid. Discharge to sewer with a large excess of water. The sludge may be added to land fill.
