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

Inhalation Dizziness. Drowsiness. Dullness. Headache. Sore throat.
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.
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
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 PACKAGING & LABELLING
Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Personal protection: self-contained breathing apparatus.
Marine pollutant.

2-VINYL TOLUENE ICSC: 0733
IMPORTANT DATA
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 with fire or explosion hazard. Reacts with strong oxidants and strong acids.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 50 ppm as TWA, 100 ppm as STEL; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: 100 ppm, 490 mg/m; Peak limitation category: I(2); (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and by ingestion.

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the nervous system.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. The liquid defats the skin. The substance may have effects on the liver and kidneys, resulting in tissue lesions.
PHYSICAL PROPERTIES
Boiling point: 170C
Melting point: -69C
Relative density (water = 1): 0.91
Vapour pressure, Pa at 25C: 240
Relative vapour density (air = 1): 4.1
Flash point: 60C o.c.
Auto-ignition temperature: 494C
Explosive limits, vol% in air: 1.9-6.1
Octanol/water partition coefficient as log Pow: 3.580
