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, thyroid, skin.

Potential Health Effects
Eye: Causes severe eye irritation. May cause eye burns. Vapors cause eye irritation.
Skin: 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 been recorded.
Ingestion: 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 GI tract.
Inhalation: 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: 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 thyroid gland.

Section 4 - First Aid Measures

Eyes: In case of contact, immediately flush eyes with plenty of water for a t least 15 minutes. Get medical aid immediately.
Skin: 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.
Ingestion: 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.
Inhalation: 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

General Information: 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

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: 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. Provide ventilation.

Section 7 - Handling and Storage

Handling: 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.
Storage: Store in a cool, dry place. Store in a tightly closed container.

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: 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.
