ICSC 0733 - 2-VINYL TOLUENE

2-VINYL TOLUENE	ICSC: 0733 (July 1997)
o-Methyl styrene 1-Ethenyl-2-methylbenzene o-Vinyl toluene

CAS #: 611-15-4

UN #: 2618

EC Number: 210-256-7

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Flammable. Heating will cause rise in pressure with risk of bursting. Above 60°C explosive vapour/air mixtures may be formed.	NO open flames. Above 60°C use a closed system, ventilation and explosion-proof electrical equipment.	Use water spray, foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

PREVENT GENERATION OF MISTS!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Dizziness. Drowsiness. Lethargy. Headache. Sore throat.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin	Dry skin. Redness.	Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness.	Wear safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Abdominal pain. Nausea. Vomiting.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Rest. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: self-contained breathing apparatus. Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 3; UN Pack Group: III
STORAGE
Separated from strong oxidants and strong acids. Well closed. Keep in a well-ventilated room. Store only if stabilized.
PACKAGING
Marine pollutant.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. Physical dangers The vapour is heavier than air and may travel along the ground; distant ignition possible. Chemical dangers The substance may polymerize due to warming. This generates fire or explosion hazard. Reacts with strong oxidants and strong acids.	Formula: CH₃C₆H₄CH=CH₂ / C₉H₁₀ Molecular mass: 118.2 Boiling point: 170°C Melting point: -69°C Relative density (water = 1): 0.91 Vapour pressure, Pa at 25°C: 240 Relative vapour density (air = 1): 4.1 Flash point: 60°C o.c. Auto-ignition temperature: 494°C Explosive limits, vol% in air: 1.9-6.1 Octanol/water partition coefficient as log Pow: 3.580

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation and by ingestion. Effects of short-term exposure The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the nervous system.	Inhalation risk A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure Repeated or prolonged contact with skin may cause dermatitis. The substance defats the skin, which may cause dryness or cracking. The substance may have effects on the liver and kidneys. This may result in tissue lesions.
