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.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Above 27C explosive vapour/air mixtures may be formed.
Above 27C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


Inhalation Drowsiness. Headache. Nausea. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
Skin Redness. Dry skin.
Protective gloves.
Refer for medical attention.
Eyes Redness. Pain.
Safety goggles, or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Abdominal pain. (See Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. 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. Do NOT let this chemical enter the environment. (Extra personal protection: filter respirator for organic gases and vapours.)

CHLOROBENZENE ICSC: 0642
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on heating, on contact with hot surfaces or flames producing toxic and corrosive fumes. Reacts violently with strong oxidants causing fire and explosion hazard. Attacks rubber and some plastic.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 10 ppm as TWA; A3; BEI issued; (ACGIH 2003).
MAK: 10 ppm, 47 mg/m; Peak limitation category: II(2); Pregnancy risk group: C; (DFG 2003).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the skin. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. The substance may cause effects on the central nervous system, resulting in lowering of consciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin. The substance may have effects on the liver and kidneys.
PHYSICAL PROPERTIES
Boiling point: 132C
Melting point: -45C
Relative density (water = 1): 1.11
Solubility in water, g/100 ml at 20C: 0.05
Vapour pressure, kPa at 20C: 1.17
Relative vapour density (air = 1): 3.88
Relative density of the vapour/air-mixture at 20C (air = 1): 1.03
Flash point: 27C c.c.
Auto-ignition temperature: 590C
Explosive limits, vol% in air: 1.3-11
Octanol/water partition coefficient as log Pow: 2.18-2.84
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms. It is strongly advised that this substance does not enter the environment.
NOTES
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
