Material Safety Data Sheet
Zinc iodide, 98+%
Section 1 - Hazards Identification
EMERGENCY OVERVIEW
Appearance: almost white crystalline powder.
Danger! Causes eye and skin burns. Causes digestive and respiratory tract burns. Air
sensitive. Light sensitive. Hygroscopic (absorbs moisture from the air). The toxicological
properties of this material have not been fully investigated.
Target Organs: Eyes, skin, mucous membranes.
Potential Health Effects
Eye: Causes eye burns.
Skin: Causes skin burns.
Ingestion: Causes gastrointestinal tract burns. The toxicological properties of this
substance have not been fully investigated.
Inhalation: Causes chemical burns to the respiratory tract. The toxicological properties of
this substance have not been fully investigated.
Chronic: Prolonged exposure to iodides may produce iodism in sensitive individuals.
Symptoms could include skin rash, running nose and headache. Chronic exposure may
cause effects similar to those of acute exposure.
Section 2 - First Aid Measures
Eyes: In case of contact, immediately flush eyes with plenty of water for a t least 15
minutes. Get medical aid.
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: If swallowed, do NOT induce vomiting. Get medical aid immediately. If victim is
fully conscious, give a cupful of water. Never give anything by mouth to an unconscious
person.
Inhalation: Get medical aid immediately. Remove from exposure and move to fresh air
immediately. If breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable
mechanical device such as a bag and a mask.
Notes to Physician: Treat symptomatically and supportively.
Section 3 - Personal Protection
Personal Protective Equipment
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by
OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard
EN166.
Skin: Wear appropriate protective gloves to prevent skin exposure.
Clothing: Wear appropriate protective clothing to minimize contact with skin.
Respirators: A respiratory protection program that meets OSHA's 29 CFR 1910.134 and
ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever
workplace conditions warrant respirator use.
