Hazard Information

Chemical Properties

Yellow crystals containing 30% silver, soluble in water. Slightly soluble in alcohol and acetone; insoluble in ether and chloroform.

General Description

A white to light colored solid paste. Contains about 35% water, which reduces its tendency toward rapid decomposition or explosion. Considered safe for storage, handling and shipping, but should be treated as an explosive. Contact may cause irritation to skin, eyes, and mucous membranes. May be toxic by ingestion.

Air & Water Reactions

Water soluble [Hawley].

Reactivity Profile

silver picrate may be ignited by heat, sparks or flames. The DRIED OUT material may explode if exposed to heat, flame, friction or shock.

Health Hazard

Some are toxic and may be fatal if inhaled, swallowed or absorbed through skin. Contact may cause burns to skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.

Hazard

Severe explosion risk. Very toxic.

Potential Exposure

Used in antibacterial medicines.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

Shipping

UN1347 Silver picrate, wetted with not ,30 % water, by mass, Hazard Class: 4.1; Labels: 4.1-Flammable solid.

Incompatibilities

Organics or other oxidizable materials. Dried out material is unstable and a severe explosion risk; protect from shock, light, and vibration.
