Section 3 - Hazards Identification

EMERGENCY OVERVIEW
Appearance: white or yellow-white solid.
Caution! May cause eye, skin, and respiratory
tract irritation. Inhalation of fumes may cause metal-fume fever.
The toxicological properties of this material have not been fully
investigated.
Target Organs: No data found.
Potential Health Effects
Eye:
Dust may cause mechanical irritation.
Skin:
Prolonged and/or repeated contact may cause irritation and/or
dermatitis.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. Moderately toxic to humans by ingestion. The toxicological
properties of this substance have not been fully investigated.
Inhalation:
Effects may be delayed. May cause respiratory tract irritation.
Inhalation of fumes may cause metal fume fever, which is
characterized by flu-like symptoms with metallic taste, fever,
chills, cough, weakness, chest pain, muscle pain and increased white
blood cell count. The toxicological properties of this substance have
not been fully investigated. Can produce delayed pulmonary edema.
Zinc oxide dust is considered to be of low toxicity and is classified
as a nuisance particulate by the ACGIH. However, inhalation fumes or
very fine dust may causes "zinc fume fever", which is characterized
by flu-like symptoms with metallic taste, coughing, weakness,
fatigue, muscular pain, and nausea, followed by fever and chills.
Onset of symptoms occurs about 4-12 hours after exposure.
Chronic:
Effects may be delayed.
Section 4 - First Aid Measures
|
Eyes:
Flush eyes with plenty of water for at least 15 minutes, occasionally
lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid. 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 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. Material will not burn.

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. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
Section 7 - Handling and Storage
|
Handling:
Minimize dust generation and accumulation. Avoid contact with eyes,
skin, and clothing. Keep container tightly closed. Use with adequate
ventilation. Wash clothing before reuse. Avoid breathing dust.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
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.
