Eye: Immediately flush with fresh water for 15 minutes.
External: Wash continuously with fresh water for 15 minutes.
Internal: Rinse out mouth, give 1 to 2 cups of water or milk, induce vomiting. Call a physician or poison control at once.
Section 5 鈥? Fire Fighting Measures
Non-flammable, noncombustible solid. NFPA CODE
When heated to decomposition, emits toxic fumes of iodide and various iodine compounds. None Established
Fire Fighting Instructions: Use triclass, dry chemical fire extinguisher. Firefighters should wear PPE
and SCBA with full facepiece operated in positive pressure mode.
Section 6 鈥? Accidental Release Measures
Restrict unprotected personnel from area. Sweep up, place in sealed bag or container and dispose. Ventilate area and wash spill site
after material pickup is complete. See Sections 8 and 13 for further information.
Section 7 鈥? Handling and Storage
Flinn Suggested Chemical Storage Pattern: Inorganic #2. Store with acetates, halides, sulfates, sulfites, thiosulfates and
phosphates. Store in a cool dry place. Store in a Flinn Chem-Saf bag; the substance sublimes. Frequently oxidizes metal shelves or
metal containers in proximity to the iodine. Use and dispense in a hood.
Section 8 鈥? Exposure Controls , Personal Protection
Avoid contact with eyes, skin and clothing. Wear chemical splash goggles, chemical-resistant gloves and chemical-resistant apron.
Use ventilation to keep airborne concentrations below exposure limits. Always wear a NIOSH-approved respirator with proper
cartridges or a positive pressure, air-supplied respirator when handling this material in emergency situations (spill or fire).
Exposure guidelines: ceiling 0.1 ppm (OSHA)
