IC1967:
We have a customer who wants to dispose of IBCs of waste Sodium Nitrite solution of varying concentrations -what is the concentration threshold that the Sodium Nitrite needs to be where it has to be consigned as UN 3219 NITRITES, INORGANIC, AQUEOUS SOLUTION, N.O.S., Class 5.1 oxidizing?
Hi IC1967,
There is no “concentration threshold” for this substance.
Correctly written for your paperwork, the word “WASTE” needs to be inserted in between the UN number and the Proper Shipping Name :
UN 1500 WASTE SODIUM NITRATE SOLUTION, 5.1 (6.1), PGIII (E)
UN 1500 does not turn into the substance you mentioned because of its concentration.
The only time that its UN number (and name) changes is if there are any other substances added in to the solution.
From the info you’ve given, it looks like you’re good to go, but it is UN 1500.
