Potential Health Effects
----------------------------------
Inhalation: Corrosive. Vapors severely irritate and can burn the mucous membranes and respiratory
REAGENTS, INC.--MSDS--IODINE PAGE -2-
tract. Excessive tears, rhinitis, tightness in the chest, sore throat, headache and delayed pulmonary
edema can result. Inhalation of concentrated vapors may be fatal.
Ingestion: Corrosive. Can cause severe burns of the mouth, throat and stomach. Causes abdominal
pain, diarrhea, fever, vomiting, stupor and shock. Probable lethal dose is 2 to 4 gm of free iodine.
Skin Contact: Corrosive. Liquid contact may cause blistering burns, irritation, and pain. Vapors may
be severely irritating to the skin.
Eye Contact: Corrosive! Vapors are severely irritating and may cause damage to the eyes. Contact may
cause severe burns and permanent eye damage.
Chronic Exposure: Chronic exposure to iodine may cause insomnia, conjunctivitis, inflammation of the
nasal mucous, bronchitis, tremor, rapid heart beat, diarrhea and weight loss. Allergic sensitization may
occur.
Aggravation of Pre-existing Conditions: Persons with pre-existing skin disorders, eye problems,
impaired respiratory function, or disease of the thyroid, lungs, or kidney may be more susceptible to the
effects of the substance.
4. First Aid Measures
Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention immediately. Observe for the development of pulmonary edema.
Ingestion: Induce vomiting immediately as directed by medical personnel. Never give anything by mouth
to an unconscious person. Get medical attention immediately.
Skin Contact: Wipe off excess material from skin then immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes. Get medical attention immediately.
Wash clothing before reuse. Thoroughly clean shoes before reuse. Iodine stains can be removed by
immediately washing skin with 5% sodium thiosulfate solution.
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper
eyelids occasionally. Get medical attention immediately.
5. Fire Fighting Measures
Fire: Not combustible, but substance is a strong oxidizer and its heat of reaction with reducing agents
or combustibles may cause ignition.
Explosion: Contact with oxidizable substances and incompatibles may cause extremely violent
combustion.
Fire Extinguishing Media: Use any means suitable for extinguishing surrounding fire. Water spray
may be used to keep fire-exposed containers cool.
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.
6. Accidental Release Measures
Notify safety personnel of iodine spill or leaks. Ventilate area of leak or spill. Wear protective equipment
as specified in Sect. 8. Isolate hazard area. Keep unnecessary and unprotected personnel from entering.
Collect and containerize as much solid iodine as possible. Cover the spill area with an excess of
REAGENTS, INC.--MSDS--IODINE PAGE -3-
reducing agent (sodium thiosulfate, bisulfate, or ferrous salts in 3M sulfuric acid) and then neutralize
with soda ash. Collect slurry into approved containers.
7. Handling and Storage
Keep in a tightly closed container. Store in a cool, dry, ventilated area away from sources of heat or
ignition. Protect against physical damage. Store separately from reactive or combustible materials, and
out of direct sunlight. 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:
-OSHA Permissible Exposure Limit (PEL):
0.1 ppm Ceiling
-ACGIH Threshold Limit Value (TLV):
0.1 ppm (STEL) ceiling
Ventilation System: A system of local and/or general exhaust is recommended to keep employee
exposures below the Airborne Exposure Limits. 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 document, Industrial Ventilation, A Manual of Recommended
Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved): If the exposure limit is exceeded, wear a supplied air, full
face-piece respirator, air-lined hood, or full face-piece self-contained breathing apparatus. This
substance has unknown warning properties.
Skin Protection: Wear impervious protective clothing, including boots, gloves, lab coat, apron or
coveralls, as appropriate, to prevent skin contact.
Eye Protection: Use chemical safety goggles and/or a full face shield where splashing is possible.
Maintain eye wash fountain and quick-drench facilities in work area.
9. Physical and Chemical Properties
