Section 3 - Hazards Identification
Appearance: black-violet solid.
Danger! Causes burns by all exposure routes.
Harmful if swallowed, inhaled, or absorbed through the skin. May
cause allergic skin reaction. At ordinary temperatures, iodine
sublimes to a violet gas with a characteristic, irritating odor.
Target Organs: Respiratory system, eyes,
Potential Health Effects
Causes severe eye irritation. May cause eye burns. Vapors cause
Harmful if absorbed through the skin. May cause severe irritation
and possible burns. Rare instances of allergic reactions to topical
iodine solutions characterized by fever and generalized skin
eruptions have lead to death. At least one death after topical
application of a strong iodine tincture to one-third of the body has
Harmful if swallowed. May cause burns to the digestive tract.
Iodine is an easily oxidizable substance. Food that is present in the
GI tract will oxidize iodine to iodide which is not corrosive to the
Harmful if inhaled. Causes severe respiratory tract irritation.
Extreme exposures could result in a build-up of fluid in the lungs
(pulmonary edema) that might be fatal in severe cases.
Readily sublimed having a violet vapor (Hawley's Condensed Chemical
Dictionary). Inhalation of iodine vapor is intensely irritating to
mucous membranes and adversely affects both the upper and lower
portions of the pulmonary tract (Doc of TLV).
Chronic exposure can lead to iodism characterized by headache,
excess salivation, nasal discharge, conjunctivitis, laryngitis,
bronchitis, stomatitis, enlarged submaxillary glands, and skin
rashes. Chronic ingestion of iodides during pregnancy has resulted
in fetal death, severe goiter, and cretinoid appearance of the
newborn. Chronic exposure can affect thyroid function. Some
references (e.g. Dreisbach's Handbook) say that iodine and iodine
compounds are potent sensitizers and that repeated contact may cause
sensitivity dermatitis, laryngeal edema, serum sickness with lymph
node enlargement, and joint pain and swelling.
Iodine in very small quantities is critical for proper function of
the thyroid. If deficient, can cause goiter, an enlargement of the
Section 4 - First Aid Measures
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid immediately.
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
POISON material. If swallowed, get medical aid immediately. Only
induce vomiting if directed to do so by medical personnel. Never give
anything by mouth to an unconscious person.
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Substance is noncombustible. Vapors may accumulate
in confined spaces
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire.

Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated
in Section 8.
Vacuum or sweep up material and place into a suitable disposal
container. Avoid runoff into storm sewers and ditches which lead to
waterways. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Section 7 - Handling and Storage
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Do not get in eyes, on skin, or on
clothing. Keep container tightly closed. Do not ingest or inhale.
Store in a cool, dry place. Store in a tightly closed container.
Section 8 - Exposure Controls, Personal Protection
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower.
