Eliminate all ignition sources (no smoking, flares, sparks or flame) within at least 15m. Do NOT touch or walk through this product. Stop leak if safe to do so. Prevent entry into waterways, drains, confined areas. Prevent dust cloud. Use clean non-sparking tools to collect material and place it into loosely-covered plastic containers for later disposal.
SEEK EXPERT ADVICE ON HANDLING AND DISPOSAL.

Not available.

Sweep up (avoid generating dust) and using clean non-sparking tools transfer to a clean, suitable, clearly labelled container for disposal in accordance with local regulations.
Most organisations using silver compounds collect all silver residues for subsequent recovery. Any solids spilt may be swept up for eventual recovery or disposal. Solutions could be washed to drain with a large volume of water, or alternatively treated with a salt solution and the resulting silver chloride collected for subsequent recovery.

Avoid substance contact. Avoid generation of dusts: do not inhale dusts. Ensure supply of fresh air in enclosed rooms.
Wear protective clothing specified for normal operations (see Section 8)
Avoid ingestion and inhalation of vapour or dust. Avoid contact with eyes, skin, clothing and other combustible materials. Avoid prolonged or repeated exposure. If ingested, seek medical advice immediately and show the container or the label. Minimise dust generation and accumulation. Ensure good ventilation at the workplace. Use with adequate ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. This substance is an oxidiser and its heat of reaction with reducing agents or combustibles may cause ignition. Heat, shock, friction, or contact with other materials may cause fire or explosion. Keep away from heat and all sources of ignition - No smoking. Keep container dry. Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Discard contaminated shoes.

Maintain eyewash fountain and safety shower in work area.
In industrial situations maintain the concentrations values below the TWA. This may be achieved by process modification, use of local exhaust ventilation, capturing substances at the source, or other methods.

The use of a face shield, chemical goggles or safety glasses with side shield protection as appropriate.
Must comply with Australian Standards AS 1337 and be selected and used in accordance with AS 1336.

Hand protection should comply with AS 2161, Occupational protective gloves - Selection, use and maintenance.
Recommendation: Excellent: NR latex, vinyl and neoprene. Good: Nitrile rubber gloves

Final choice of personal protective equipment will depend on individual circumstances and/or according to risk assessments undertaken.
Flame retardant protective clothing. Clean clothing or protective clothing should be worn, preferably with an apron. Clothing for protection against chemicals should comply with AS 3765 Clothing for Protection Against Hazardous Chemicals.

Where ventilation is not adequate, respiratory protection may be required. Avoid breathing dust, vapours or mists. Respiratory protection should comply with AS 1716 - Respiratory Protective Devices and be selected in accordance with AS 1715 - Selection, Use and Maintenance of Respiratory Protective Devices. Filter capacity and respirator type depends on exposure levels. In event of emergency or planned entry into unknown concentrations a positive pressure, full-face piece SCBA should be used. If respiratory protection is required, institute a complete respiratory protection program including selection, fit testing, training, maintenance and inspection.

Many reactions may cause explosion.
Reacts with ammonia to form compounds that are sensitive to mechanical shock.
Silver nitrate mixed with dry powdered magnesium may ignite explosively on contact with a drop of water.

AgNO₃

No further relevant information available.

Stable at room temperature in closed containers under normal storage and handling conditions. Light sensitive. Darkens on exposure to light.

Reacts with acetylene in presence of ammonia to form silver acetylide, a sensitive powerful detonator when dry. In the absence of ammonia, or when calcium acetylide is added to a silver nitrate soln, explosive double salts of silver acetylide and silver nitrate are produced. Mercurous acetylide precipitates silver acetylide from aqueous nitrate. Reaction with chlorosulfonic acid is violent with nitrosulfonic acid being formed. Reduced by hydrogen sulfide in the dark. Easily reduced to metallic silver by ferrous salts, arsenites, hypophosphites, tartrates, sugars, tannins, volatile oils. Dry powdered magnesium and silver nitrate may ignite explosively on contact with a drop of water. Reaction with ammonium hydroxide, sodium hydroxide and stirring may be explosive. Reaction with phosphorus, or sulphur, and shock may be violently explosive. Reaction with charcoal and shock may result in ignition. Highly sensitive explosive is formed when calcium carbide is added to silver nitrate solution. Reaction with alcohols may form an explosive fulminate. When purified phosphine was passed rapidly into a concentrated solution of silver nitrate an explosion occurred.

Heat, flame, sources of ignition, light, contamination and incompatible materials.

Corrosive. Can cause blurred vision, redness, pain, severe tissue burns and eye damage.

Corrosive. Symptoms of redness, pain, and severe burn can occur.

Corrosive. Swallowing can cause severe burns of the mouth, throat, stomach and gastrointestinal tract.Can cause sore throat, vomiting, diarrhoea. Poison. Symptoms include pain and burning in the mouth, blackening of the skin and mucous membranes, throat, and abdomen, salivation, vomiting of black material, diarrhoea, collapse, shock, coma and death. Ingestion of soluble silver salts may cause argyria, characterised by permanent blue-gray pigmentation of the skin, mucous membranes, and eyes. Lethal dose for humans is 2 grams, or about 28.6 mg/kg.

Extremely destructive to tissues of the mucous membranes and upper respiratory tract. Symptoms may include severe irritation, burning sensation, coughing, wheezing, laryngitis, shortness of breath, breathing difficulty, headache, nausea, vomiting and possible coma. May be absorbed into the body following inhalation with symptoms paralleling those from ingestion exposure. Dust deposits in the lungs may resemble a form of pneumoconiosis. Inhalation of silver metal dust and fume or of soluble silver compounds may eventually cause argyria, an unsightly blue-gray discolouration of the skin and mucous membranes, including gum tissue and conjunctiva of the eyes.

Highly toxic for aquatic organisms. May cause long-term adverse effects in the aquatic environment. Forms corrosive mixtures with water even if diluted.

Methods for the determination of biodegradability are not applicable to inorganic substances.

BCF: 200; Highly bioaccumulative (Biological Concentration Factor 100-1000). Do not allow to enter waters, waste water, or soil!
