Material Safety Data Sheet
Iodine Monochloride, WIJS Solution
Ingestion:
Ingestion results in irritation/corrosion of mucous membranes, mouth, stomach with edema (severe) of the pharynx,
larynx; abdominal spasms, nausea, vomiting, colitis, hypotension, circulatory collapse, delerium, coma possible. One
ounce (30 mL) can burn holes in throat; five ounces can cause death.

coughing, choking, throat swelling, fluid in the lungs, headache and dizziness.
Chronic:
Sensitization, hypersensitivity, dental erosion, ulceration of jaw, nose, throat; throat and lung disease (bronchitis,
pneumonia, laryngitis), gastrointestinal disturbances, "iodism", tissue necrosis,skin blackening, painful joint
swelling,conjunctivitis
Section 4 - First Aid Measures
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids until
chemical is gone. Get medical aid at once.
Skin:
Get medical aid at once. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated
clothing and shoes.
Ingestion:
Do NOT induce vomiting. Get medical aid at once. Give 1 ounce of milk of magnesia. Give conscious victim large
quantities of water to dilute acid.
Inhalation:
Give artificial respiration if necessary. Get medical aid. Keep victim warm, at rest. Move victim to fresh air.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
General Information:
Vapors heavier than air, may travel considerable distance and flash back from source of ignition. Avoid breathing
corrosive vapors. Moderate fire and explosion hazard when exposed to heat or flame. Acetic acid may react
explosively with oxidizing materials or give off flammable/explosive vapors above its flash point (104F). Use flooding
quantities of water as fog (streams may spread fire), cool all containers. Flammable/explosive vapors given off above
104癋.
Extinguishing Media:
In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
Autoignition Temperature:
