Potential Health Effects
----------------------------------
Inhalation: May cause irritation to the respiratory tract. Symptoms may include coughing and shortness of
breath.
REAGENTS, INC.--MSDS鈥擯OTASSIUM IODIDE PAGE 2 OF 5
Ingestion: Large oral doses may cause irritation to the gastrointestinal tract.
Skin Contact: May cause irritation with redness and pain.
Eye Contact: May cause irritation, redness and pain.
Chronic Exposure: Chronic ingestion of iodides may produce "iodism," which may be manifested by skin rash,
running nose, headache and irritation of mucous membranes. Weakness, anemia, loss of weight, and general
depression may also occur.
Aggravation of Pre-existing Conditions: No information found.
4. First Aid Measures
Inhalation: Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion: Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an
unconscious person.
Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated
clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention if
irritation develops.
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids
occasionally. Get medical attention if irritation persists.
5. Fire Fighting Measures
Fire: Not considered to be a fire hazard.
Explosion: Not considered to be an explosion hazard.
Fire Extinguishing Media: Use any means suitable for extinguishing surrounding fire.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained
breathing apparatus with full-facepiece operated in the pressure demand or other positive pressure mode.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills:
Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust
dispersal.
7. Handling and Storage
Keep in a tightly closed light-resistant container, stored in a cool, dry, ventilated area. Protect against physical
damage. Isolate from incompatible substances. Prolonged storage is not recommended because of possible
degradation problems, including yellowing of the potassium iodide product. Always inspect the potassium
iodide's color and overall quality before use. Containers of this material may be hazardous when empty since
they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits: None established.
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. Please refer to the ACGIH
REAGENTS, INC.--MSDS鈥擯OTASSIUM IODIDE PAGE 3 OF 5
document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
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 (NIOSH type N95 or better filters) may be
worn. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P filter.
For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-
supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient
atmospheres.
Skin Protection: Gloves and lab coat, apron or coveralls.
Eye Protection: Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work
area.
9. Physical and Chemical Properties
Appearance: White crystals.
Odor: Odorless.
Solubility: 140 grams/100 gm in water.
Density: 3.1
pH: 7-9
% Volatiles by volume @ 21C (70F): 0
Boiling Point: 1330C (2426F)
Melting Point: 680C (1256F)
Vapor Density (Air=1): No information found.
Vapor Pressure (mm Hg): 1 @ 745C (1373F)
Evaporation Rate (BuAc=1): No information found.
10. Stability and Reactivity
Stability: Stable under ordinary conditions of use and storage. On long exposure to air becomes yellow due to
release of iodine.
Hazardous Decomposition Products: Oxides of the contained metal and halogen, possibly also free, or ionic
halogen.
Hazardous Polymerization: Will not occur.
Incompatibilities: Diazonium salts; diisopropyl peroxydicarbonate; oxidants; bromine and chlorine
trifluorides; fluorine perchlorate; calomel (mercurous chloride); potassium chlorate; metallic salts; tartaric
and other acids.
Conditions to Avoid: Air, moisture, light and incompatibles.
