Causes burns. Very toxic to aquatic organisms, may cause long-term adverse
Main Hazards
effects in the aquatic environment.
Silver nitrate is caustic and irritating to the skin, eyes and mucous
membranes, producing a persistent black stain, with possible tissue
destruction. Absorbtion over a long period may cause"Argyria", a blue/grey
discolouration of various tissues. Industrial argyria may be local, involving
the formation of blue/grey particles in the skin and the conjunctivae, or
generalised, which appears early on the face, spreading to the hands. This is
only normally manifest after many years of gross over-exposure. Ingestion
will cause violent abdominal pain and vomiting. Wood impregnated with silver
nitrate presents a high risk of self-ignition. 聽 聽 聽
4. FIRST AID MEASURES
Symptoms of over-exposure may include the following for severe cases.
First Aid
Lower levels of exposure may produce less severe symptoms.
Inhalation- irritation of the respiratory tract with coughing and difficulty in
breathing.
Ingestion- burning sensation in the mouth and throat, violent abdominal pain,
vomiting, collapse and death.
Eyes- severe pain, blindness.
Skin- severe pain, tissue destruction, black stain.
First-aid treatment for severe cases. 聽
First Aid - Inhalation remove from exposure and allow to rest in fresh air. Seek medical attention
urgently. 聽
rinse mouth with water and give water or milk to drink. Seek medical attention
First Aid - Ingestion
urgently.
First Aid - Eyes irrigate with water or isotonic saline solution for 15 minutes. Seek medical
attention urgently. 聽

5. FIRE FIGHTING MEASURES (continued)
Although the compound is not flammable, it will assist a fire, producing irritant
and toxic fumes of oxides of nitrogen. Wear self contained breathing
apparatus and personal protective equipment. Use any extinguishing media
suitable for the surrounding fire. 聽
6. ACCIDENTAL RELEASE MEASURES
Wearing personal protective equipment (see section 8) collect up the spillage
in a suitable container and retain. Wash the site of the spillage with large
amounts of water. Do not allow wash water to enter natural water courses.
The addition of salt solution will result in a precipitate of insoluble non-
hazardous silver chloride. Any wooden articles contaminated with silver
nitrate should be treated to precipitate the inert chloride, to prevent any
possible risk of later spontaneous ignition. 聽
7. HANDLING AND STORAGE
Good industrial hygiene practices should be observed. Use only under
Handling (JM)
conditions of good local ventilation. Avoid contact with skin and eyes. Do not
eat, drink, smoke or apply cosmetics whilst using this material. 聽
Store in a sealed container in a cool, dry chemical store. Do not store on
Storage (JM)
wooden surfaces. Protect from water and direct sunlight.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Users of large amounts of silver nitrate should consider the application of
engineering control measures such as total enclosure and remote operation
where possible. The following exposure standards have been established -
U.K. Occupational Exposure Standard for silver, soluble compounds (as Ag)
- 0.01 mg/m鈥?
USA ACGIH TLV for silver, soluble compounds as Ag - 0.01 mg/m鈥?
USSR Exposure Limit Value - silver nitrate - 0.50 mg/m鈥?
(Roseman, Moss and Kon, Journal of Occupational Medecine, Vol 21, No. 6,
recommend that monitoring of the silver in air concentration and periodic slit
lamp eye examinations of the exposed workforce are helpful ways to assess
the bodily silver content.)
If a risk of inhalation exists, users should wear an appropriate filter type
respirator. When using this material, users MUST wear chemically resistant,
impervious gloves and suitable eye protection such as goggles or, preferably,
a visor. 聽 聽

10. STABILITY AND REACTIVITY
This material is supplied in a stable condition. Silver nitrate is a strong
oxidising agent. Wood and other organic materials which have become
impregnated with silver nitrate are reported as being possibly spontaneously
flammable when dry.
Contact with ammonia may produce explosive compounds. Ammoniacal
silver nitrate solutions should never be stored. Violent reactions have been
reported between silver nitrate and the following materials - acetaldehyde,
phosphorus, ammonia and ethanol, acetylene and derivatives, acrylonitrile,
ammonia and sodium carbonate, ammonia and sodium hydroxide, arsenic, 1,
3-butadiyne, buten-3-yne, chlorine trifluoride, chlorosulfonic acid, disilver
ketenide, ethanol, phosphine, phosphonium iodide.
Silver may have a catalytic effect upon the oxidation of some organic
compounds. When processing silver and its salts, care should be taken to
avoid the formation of explosive compounds such as the nitride, oxalate or
tartrate. Mixtures of silver nitrate with titanium powder are reported as being
explosive when subjected to friction or impact or upon heating. An intimate
mixture of silver nitrate and aluminium powder or magnesium powder is
reported as exploding upon the addition of water. 聽

LDLo (oral-rabbit) 800 mg/kg : LDLo (unrecorded-man) 29 mg/kg. i.e. Toxic.
Eye-rabbit; 1 to 10 mg - moderate to severe irritant
There is evidence that silver nitrate is an experimental tumerigen.
Reproductive and mutagenic effects have been observed in animals, no
human data is available.

12. ECOLOGICAL INFORMATION
The threshold concentration for fresh and salt water fish is 0.01 ppm as Ag.
The threat is ascribed to mainly to the nitrate. Silver will be precipitated by
any naturally occuring chlorides as silver chloride. 聽
13. DISPOSAL
Return accumulated waste material to the refinery for metal recovery, or
dispose of in accordance with local and national regulations. 聽
