Potassium iodide is a chemical compound, medication, and dietary supplement. As a medication it is used to treat hyperthyroidism, in radiation emergencies, and to protect the thyroid gland when certain types of radiopharmaceuticals are used. As a supplement it is used in those who have low intake of iodine in the diet. It is on the World Health Organization's List of Essential Medicines, the safest and most effective medicines needed in a health system. Potassium iodide is also used for the iodization of salt. Potassium iodide is used as a nutritional supplement in animal feeds and also in the human diet.

Procedure
Sample solution: Dissolve 500 mg of Potassium Iodide in 10 mL of water.
Analysis: Add 35 mL of hydrochloric acid to the Sample solution, and titrate with 0.05 M potassium iodate until the dark brown solution that is produced becomes pale brown. Add 2–3 drops of amaranth and continue the titration slowly until the red color just changes to yellow. Each mL of 0.05 M potassium iodate is equivalent to 16.60 mg of KI.
Acceptance criteria: 99.0% to 101.5% on the dried basis.
Iodate solution: Dilute 1 mL of potassium iodate solution (1 in 2500) with water to 100 mL.
Standard solution: Dissolve 100 mg of Potassium Iodide in ammonia- and carbon dioxide-free water and add 1 mL of Iodate solution to obtain 10 mL of solution. Transfer to a color-comparison tube, add 1 mL of starch and 0.25 mL of 1.0 N sulfuric acid, and mix.
Sample solution: Dissolve 1.1 g in sufficient ammonia- and carbon dioxide-free water to obtain 10 mL of solution. Transfer to a color-comparison tube, add 1 mL of starch TS and 0.25 mL of 1.0 N sulfuric acid, and mix.
Acceptance criteria: Any color produced in the Sample solution does not exceed that produced in the Standard solution (NMT 4 µg/g).
Limit of Nitrate, Nitrite, and Ammonia:
Sample solution: Dissolve 1 g in 5 mL of water.
Analysis: To the Sample solution contained in a test tube of 40-mL capacity add 5 mL of 1 N sodium hydroxide and 200 mg of aluminum wire. Insert a pledget of purified cotton in the upper portion of the test tube and place a piece of moistened red litmus paper over the mouth of the tube. Heat the test tube and its contents in a steam bath for 15 min.
Acceptance criteria: No blue coloration of the paper is discernible.
Thiosulfate and Barium:
Sample solution: Dissolve 0.5 g in 10 mL of ammonia- and carbon dioxide-free water.
Analysis: Add 2 drops of 2 N sulfuric acid.
Acceptance criteria: No turbidity develops within 1 min.
Alkalinity:
Sample solution: Dissolve 1.0 g of Potassium Iodide in 10 mL of water.
Analysis: Add 0.1 mL of 0.1 N sulfuric acid and 1 drop of phenolphthalein to the Sample solution.
Acceptance criteria: No color is produced.
Loss on Drying: Dry a sample at 105C for 4 h: it loses NMT 1.0% of its weight.
Packaging and Storage: Preserve in well-closed containers.

5. Fire Fighting Measures
Flammability of the Product: Non-flammable.
Products of Combustion: Hydrogen Iodide, Iodine, Oxides of Potassium etc..
Fire: Not considered to be a fire hazard.
Explosion: Not an Explosive item.
Fire Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide. Use any means suitable for extinguishing surrounding fire.
Extinguishing Media Not recommended: None specified.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures under fire conditions, it may produce toxic or irritating fumes. Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place. On decomposition it may emit hydrogen iodide. Containers may explode on heating.
6. Accidental Release Measures
Personal precautions, protective equipment, and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind. Do not touch the spilled material.
Environmental precautions: Do not let the product enter drains, soil, or water sources.
Methods and materials used for containment cleanup procedures and Storage: Contain spilled material. Do not let the product enter drains. Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow evacuating as per law.
7. Handling and Storage
Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. Wash thoroughly after handling. Do not drink, eat, or smoke while handling. Avoid contact with skin, eyes, and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Prevent any contact with hot surfaces.
Conditions for safe storage, including any incompatibilities: Store in cool, dry, and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like strong oxidizing agents, chlorinated compounds, metals & acids.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits: USA ACGIH, ACGIH TWA (ppm): 0.01 ppm Inhalable fraction
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full-face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Dust deposits on floors and other surfaces may pick up moisture and cause the surfaces to become slippery and present safety hazards. Handle in accordance with good industrial hygiene and safety practice. Wash hands after handling.
