Dear Silvernitrate-ga,
Silver Nitrate (chemical compound AgNo3) is a colorless crystalline
material that is very soluble in water. The most important compound of
Silver, it is used in the preparation of Silver salts for in chemical
analysis, in silver plating, in inks and hair dyes, and to silver
mirrors. Taken internally Silver Nitrate is a poison. It is prepared
by reaction of nitric acid with Silver, and purified by
recrystallization. Silver Nitrate is a hazardous product under the
criteria of the Federal OSHA hazard communication standard 29 CFR
1910.1200. (http://frwebgate2.access.gpo.gov/cgi-bin/waisgate.cgi?waisdocid=808488114074+9+0+0&waisAction=retrieve)
In the code of Federal regulations regarding the reportable quantities
of hazardous materials pursuant to Section 311 of The Clean Water Act
[Title 40, Volume 13, Parts 87 to 135, revised as of July 1, 1998,
from the U.S. Government printing office via GPO access, Cite:
40cfr117.3, page 621-625, Silver Nitrate in an amount exceeding 0.454
must be officially reported by Federal law. Amounts below that do not
need to be reported.
Silver Nitrate must also be clearly labeled as a poison under the code
of Federal regulations, Title 16, Volume 2, revised as of January 1,
2003, from the U.S. Government printing office via GPO access, Cite:
16cfr1500.129, page 486: commercial practices-consumer product safety
commission: "the commission finds that for those substances covered by
the Federal caustic poison Act (44 stat. 1406), the requirements of
Section 2(p)(1) of the Federal hazardous substances Act (repeated in
sec. 1500.3(b)(14)(I)) are not adequate for the protection of the
public health. Labeling for those substances, in the concentrations
listed in the Federal caustic poison Act, were required to bear the
signal word "poison." the commission concludes that the lack of the
designation "poison" would indicate to the consumer a lesser hazard
and that such would not be in the interest of the public health. Under
the authority Granted in Section 3(b) of the Act, the commission
therefore finds that for the following substances, and at the
following concentrations, the word "poison" is necessary instead of
any signal word.
Silver Nitrate is listed as item "k" and is detailed as follows:
"Silver Nitrate, sometimes known as lunar caustic, and any preparation
containing Silver Nitrate must be listed as a poison in a
concentration of 5 percent or more. (Federal Caustic Poison Act:

Silver Nitrate is also permitted as a Slimicide under Federal
Regulation Title 21, Volume 3, revised as of April 1, 2003, from the
U.S. Government printing office via GPO access, Cite: 21cfr176.300,
page 226-22, Title 21--food and drugs: part 176--indirect food
additives: paper and paperboard components. Silver Nitrate can thus be
legally used in the manufacture of paper and
Paperboard that contact food.

It is also a permitted substance as a food additive (Polymers). Code
