§ 02 · Hazards identification
Silver nitrate harmonised EU classification
CLP Annex VI · Index 047-001-00-2. A supplier SDS may add self-classified hazards — this is the legal minimum.
Precautionary statements
Codes ending in a colon introduce the action that follows — on a label they are printed as combined statements, such as P305+P351+P338.
§ 03 · Composition and identifiers
Silver nitrate structure
Silver nitrate is an ionic compound — there is no discrete AgNO3 molecule. The diagram shows the ions the crystal lattice is built from.

§ 04 · First-aid measures
Silver nitrate first aid measures
Call your national emergency number first. These are published first-aid measures, not medical advice, and they do not replace emergency services, a poison control centre or the supplier's safety data sheet.
§4–§6 below reproduce the CAMEO Chemicals entry SILVER NITRATE. CAMEO publishes response data per product entry, so the entry can describe a solution, a refrigerated liquid or a molten form rather than the pure substance in §9 — check it matches what you are handling.
Refer to the ERG "General First Aid" instructions. Specific First Aid: Contaminated clothing may be a fire risk when dry.

Fire and explosion hazard
Behavior in Fire: Increases flammability of combustibles.
Extinguishing media and tactics
SMALL FIREUse water. Do not use dry chemicals or foams. CO2 or Halon® may provide limited control.
LARGE FIREFlood fire area with water from a distance. Do not move cargo or vehicle if cargo has been exposed to heat. If it can be done safely, move undamaged containers away from the area around the fire.
FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKSFor ammonium nitrate products: Do not fight cargo fire. Withdraw, evacuate and isolate area for at least 1600 meters (1 mile). Treat as an explosive (ERG Guide 112). Do not enter area for 24 hours or until expert advice has been provided. Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. ALWAYS stay away from tanks in direct contact with flames. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn.

§ 06 · Accidental release measures
Silver nitrate spill and leak response
Containment and clean-up
Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Do not get water inside containers.
SMALL DRY SPILLWith clean shovel, place material into clean, dry container and cover loosely; move containers from spill area.
SMALL LIQUID SPILLUse a non-combustible material like vermiculite or sand to soak up the product and place into a container for later disposal.
LARGE SPILLDike far ahead of liquid spill for later disposal.
Initial isolation and evacuation
IMMEDIATE PRECAUTIONARY MEASUREIsolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.
LARGE SPILLConsider initial downwind evacuation for at least 100 meters (330 feet).
FIREIf tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. If ammonium nitrate products are in a tank, rail car or truck and involved in a fire, ISOLATE for 1600 meters (1 mile) in all directions; also, initiate evacuation including emergency responders for 1600 meters (1 mile) in all directions.

§ 13 · Disposal considerations
Dispose of waste and residues in accordance with local and national regulations — in the EU under the Waste Framework Directive 2008/98/EC. Never discharge to drains or municipal waste; hand contaminated packaging and unused product to an authorised waste-disposal company. The supplier's SDS section 13 lists the applicable waste codes for the specific product.

MSDS vs SDS
Silver nitrate MSDS vs SDS: is there a difference?
MSDS (Material Safety Data Sheet) is the older name for the same document. In the US, OSHA's Hazard Communication Standard (2012) adopted the GHS-standardised 16-section Safety Data Sheet; in the EU the format is set by REACH Annex II. So a "silver nitrate MSDS" and a "silver nitrate SDS" refer to the same document — today it is issued as an SDS. Full breakdown of the differences →

Frequently asked questions about silver nitrate
Is an MSDS the same as an SDS?
In practice, yes. MSDS (Material Safety Data Sheet) is the older name for the same document. In the US, OSHA's Hazard Communication Standard (2012) adopted the GHS-standardised 16-section Safety Data Sheet; in the EU the SDS format is set by REACH Annex II. A document you find labelled "silver nitrate MSDS" is today issued as an SDS.
What GHS pictograms does silver nitrate require?
Under the harmonised EU classification (CLP Annex VI), silver nitrate carries GHS03 and GHS05 and GHS09 with the signal word "Danger". Hazard statements: H272, H314, H400, H410. A supplier's SDS may add self-classified hazards on top of this harmonised minimum.
What should silver nitrate never be stored with?
Based on its storage class (Oxidizers), silver nitrate must not share storage with: Cyanides & sulfides; Flammable liquids; Flammable solids; Mineral acids; Organic acids; Organic peroxides & self-reactives; Reactive metals; Water-reactives. Verify against the supplier's SDS sections 7 and 10 before finalising storage.
Where can I download an official silver nitrate SDS PDF?
From your own supplier — an SDS is issued per product and supplier, so the correct PDF for an inspection is the one matching the product you actually purchased. The supplier links on this page lead to the official SDS libraries of major distributors.
