11 - Toxicological Information
SIGNS AND SYMPTOMS OF EXPOSURE
Symptoms of exposure may include burning sensation, coughing,
wheezing, laryngitis, shortness of breath, headache, nausea, and
vomiting. To the best of our knowledge, the chemical, physical,
and toxicological properties have not been thoroughly
investigated.
ROUTE OF EXPOSURE
Multiple Routes: Harmful if swallowed, inhaled, or absorbed
through skin. High concentrations are extremely destructive to
tissues of the mucous membranes and upper respiratory tract,
eyes, and skin.
12 - Ecological Information
No data available.
13 - Disposal Considerations
SUBSTANCE DISPOSAL
Cautiously acidify a 3% solution or a suspension of the material
to pH 2 with sulfuric acid. Gradually add a 50% excess of aqueous
sodium bisulfite with stirring at room temperature. An increase in
temperature indicates that a reaction is taking place. If no
reaction is observed on the addition of about 10% of the sodium
bisulfite solution initiate it by cautiously adding more acid. If
manganese, chromium, or molybdenum are present adjust the pH of
the solution to 7 and treat with sulfide to precipitate for burial
as hazardous waste. Destroy excess sulfide, neutralize, and flush
the solution down the drain. Observe all federal, state, and local
