SECTION 3: Hazards Identification
Emergency Overview:	Extremely flammable liquid that causes burns to skin, eyes and respiratory tract. Danger of serious damage to health by prolonged exposure through inhalation.
Primary Routes of Exposure:	Ingestion, inhalation, eyes, skin
Eye Contact:	Causes burns to the eyes. May cause severe eye damage.
Skin Contact:	Contact with skin causes thermal and chemical burns, redness and pain.
Inhalation:	Inhalation of vapors may depress the central nervous system causing nausea, headache, dizziness, unconsciousness and coma.
Ingestion:	Causes burns. Ingestion may cause lung damage, nausea, vomiting, and headaches.
Acute Health Effects:	Causes burns to skin, eyes and respiratory tract. May cause lung damage if aspirated into the lungs. Lithium salts are toxic to the central nervous system.
Chronic Health Effects:	Lithium salts are toxic to the central nervous system and on repeated ingestion may damage kidneys and act as a teratogen. Repeated skin contact with pentane may cause defatting and dermatitis.
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 15 minutes. A victim will need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure:	Wash the affected area immediately with water. Remove contaminated clothing 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.
