IV       FIRE AND EXPLOSION HAZARDS DATA



Flash Point (Method used): Not Flammable                                     Flammable Limits: UFL: N/A Lower: N/A

Firefighting Media: Dry chemical, carbon dioxide, water spray of foam. For larger fires, use water spray, fog or alcohol foam (1984

emergency response guidebook, DOT P 5800.3)



Fire and Explosion Hazard: Negligible fire and Negligible explosion hazard in dust form when exposed to heat or flame.

Special Fire Fighting Procedures: No acute hazard. Move container from fire area if possible. Avoid breathing vapors or dusts,

keep upwind.





V        HEALTH HAZARD INFORMATION



CERCLA Ratings (Scale 0-3): Health=U                  Fire=O             Reactivity=O               Persistence=3

Threshold Limit Value: 0.01 mg/m3



Effects of Over Exposure: As solid no known effects

Toxicity: Carcinogen status - none insoluble silver salts are considered non-irritating and relatively non-toxic.



EMERGENCY AND FIRST AID PROCEDURES:



EYES: Wash eyes immediately with large amounts of water, occasionally lifting upper and lower lids, until no evidence of chemical

remains (approximately 15-21 minutes). Get medical attention immediately.

SKIN: Remove contaminated clothing and shoes immediately. Wash affected area with soap or mild detergent and large amounts of

water until no evidence of chemical remains (approximately 10- 20 minutes). Get medical attention immediately.

INHALATION: Remove from exposure area to fresh air immediately. If breathing has stopped, perform artificial respiration. Keep

affected person warm and at rest. Get medical attention immediately.

INGESTION: If victim is conscious, immediately give 2 to 4 glasses of water and induce vomiting by touching finger to back of

throat. Get medical attention immediately.

VI       REACTIVITY DATA



Stability: Stable under normal temperatures and pressures.



Incompatibility (Material to Avoid): Silver Iodide forms impact sensitive systems with Sodium and Potassium. Silver salts and

acetylene form acetylides from ammoniacal solutions. The dried acetylides are extremely sensitive and violent. Silver salts form

explosive materials spontaneously with nitromethane. They darken on exposure to light.



Hazardous Decomposition Products: Thermal decomposition products may be corrosive fumes of hydrogen iodide.

Hazardous Polymerization: Hazardous polymerization has not been reported to occur under normal temperatures and pressures.





VII      SPILL OR LEAK PROCEDURES



Steps to Be Taken If Spilled or Released: Ventilate confined spaces. sweep up, avoiding dispersion of dust, and collect in suitable

container.



Waste Disposal Method: In accordance with governmental regulations.





VIII     SPECIAL PROTECTION INFORMATION



Respiratory Protection (Specify Type):



Ventilation: Process enclosure, local exhaust, or general dilution ventilation system.

Respirator: High Levels - High efficiency particulate respirator with a full facepiece. Supplied air respirator with a full facepiece,

helmet or hood. Self-contained breathing apparatus with a full facepiece. Firefighting- Self contained breathing apparatus with a full

facepiece, operated in pressure demand or other positive pressure mode.



Protective Gloves: Are not required but recommended.

Eye Protection: Employee must wear splash-proof or dust-resistant safety goggles to prevent eye contact with this substance.



Clothing: Protective clothing not required. Avoid repeated or prolonged contact with this substance.

Other Protective Equipment: Lab coat and apron





IX       SPECIAL PRECAUTIONS



Conditions to Avoid: Heating to decomposition and contact with incompatible substances.
