Hazards and Protection.
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear appropriate protective gloves, clothing and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
Keep away from combustible materials. Avoid contact unless wearing appropriate protective clothing. Stop leak if you can do it without risk. With clean shovel place material into clean, dry container and cover loosely; move containers from spill area.
Reacts explosively with alkali metals Mixture of silver iodate with finely divided aluminum, arsenic, copper, carbon, phosphorus, sulfur, hydrides of alkali and alkaline earth-metals; sulfides of antimony, arsenic, copper or zinc; metal cyanides, thiocyanates; or impure magnesium dioxide may react explosively, either spontaneously (especially in the presence of moisture).
Small Fires: Use water. Do not use dry chemicals or foams. carbon dioxide or Halon may provide limited control. Large Fires: Flood fire area with water from a distance.
These substances will accelerate burning when involved in a fire.
May explode from heat or contamination. May react explosively with hydrocarbons (fuels). May ignite combustibles.
Fire may produce irritating, corrosive and/or toxic gases.
Contact with eyes causes irritation. If continued for a long period, ingestion or inhalation of silver compounds can cause permanent discoloration of the skin (argyria).
Give large amount of water, induce vomiting.
Move to fresh air.
Flush with water, wash with soap and water.
Flush with water for at least 15 min.
