TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
Carbon dioxide, water spray, foam, powder.
EXPLOSION Above 43C explosive vapour/air mixtures may be formed.
Above 43C 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 Cough. Shortness of breath. Dizziness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
Skin Dry skin. Redness. Pain.
Protective gloves.
First rinse with plenty of water, then remove contaminated clothes and rinse again.
Eyes Redness. Pain.
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion
Do not eat, drink, or smoke during work.
Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Ventilation. Remove all ignition sources. 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. (Extra personal protection: filter respirator for organic gases and vapours.) Do NOT let this chemical enter the environment.
Marine pollutant.

2-CHLOROTOLUENE ICSC: 1458
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
On combustion, forms toxic and corrosive fumes including hydrogen chloride and phosgene. Reacts with oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 50 ppm as TWA; (ACGIH 2003).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin.
PHYSICAL PROPERTIES
Boiling point: 159.2C
Melting point: -35.1C
Relative density (water = 1): 1.08
Solubility in water, g/100 ml at 20C: 0.47
Vapour pressure, kPa at 20C: 0.35
Relative vapour density (air = 1): 4.4
Relative density of the vapour/air-mixture at 20C (air = 1): 1.01
Flash point: 43C c.c.
Explosive limits, vol% in air: 1 - 12.6
Octanol/water partition coefficient as log Pow: 3.4
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms. This substance may be hazardous in the environment; special attention should be given to crustacea and fish.
