SECTION 3: Hazards Identification
Emergency Overview:	Inhalation of zinc oxide fume produced from this compound in a fire may cause metal fume fever or zinc shakes consisting of chills, fever, muscular pain, nausea, and vomiting. May cause thermal burns.
Primary Routes of Exposure:	Eyes, skin, and inhalation of combustion products.
Eye Contact:	Direct contact of liquid with the eyes will cause thermal burns and possible blindness.
Skin Contact:	Liquid bursts in to flame in air, causing thermal burns to skin.
Inhalation:	Fume cause burns to the nose, mucous membranes and respiratory tract causing metallic taste, dry throat, and chills.
Ingestion:	Ingestion is an unlikely mode of entry as the material is pyrophoric.
Acute Health Effects:	Cause burns to skin, eyes and respiratory tract. Inhalation may cause chills and nausea.
Chronic Health Effects:	No serious long-term chronic effects associated with zinc compounds. Prolonged inhalation may cause laryngitis. Prolonged ingestion may cause constipation.
NTP:	No
IARC:	No
OSHA:	No

SECTION 4: First Aid Measures
Eye Exposure:	Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure:	Wash the affected area with a large volume of water applied rapidly. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists.
Inhalation:	Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.
Ingestion:	Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel.

SECTION 5: Fire Fighting Measures
