SECTION 3: Hazards Identification
Emergency Overview:	For toluene: Flammable liquid and vapor. Harmful if swallowed. May be absorbed through the skin. May effect the liver, kidneys, blood system or central nervous system. May impair fertility.
Primary Routes of Exposure:	Eye, skin, ingestion and inhalation.
Eye Contact:	Causes severe irritation to the eyes with redness and pain.
Skin Contact:	Causes irritation of the skin. May be absorbed through the skin.
Inhalation:	Inhalation causes irritation of the upper respiratory tract. Symptoms of overexposure include cause confusion, headaches, dizziness, fatigue
Ingestion:	Harmful if swallowed, swallowing may cause abdominal spasms.
Acute Health Effects:	Irritating to skin, eyes and respiratory tract. Inhalation or ingestion may lead to fatigue, confusion, headache, dizziness and drowsiness. High concentrations may cause unconsciousness and death.
Chronic Health Effects:	Reports of chronic exposure to toluene include anemia, decreased blood cell count and bone marrow hypoplasia. Liver and kidney damage may occur. Prolonged contact can cause drying of the skin, redness and dermatitis. May impair fertility.
NTP:	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 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 if directed by medical personnel.
