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 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.
PACKAGE LOTS:
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.
