We have not used this for disposal, but use salt to rinse our hands with if
we think there is a possibility of silver nitrate splatter.  The chloride
binds with the silver and you get no development on your hands.

		I don't know if it neutralizes it, but I imagine it will
reduce it - we accomplish the same thing by adding our sodium thiosulfate to
the waste silver.  However, we do not put anything down the drain - it all
gets disposed of as hazardous waste.

		Dear Netters,

		I recently visited a large histology research laboratory
where they mix
		deionized salt (yes, Morton's table salt) with their Silver
		waste and dump it down the drain.  They swear that it
neutralizes the
		Silver Nitrate waste.  Is this true?  Does anyone else use
		"protocol".  I look forward to your responses.
