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, alcohol-resistant foam, water spray, carbon dioxide.
|
|
Explosion
|
Vapour/air mixtures are explosive.
Risk of fire and explosion on contact with incompatible materials (see Chemical Dangers and Notes).
|
Above 35°C use a closed system, ventilation, and explosion-proof electrical equipment.
Do NOT expose to friction or shock.
|
In case of fire: keep drums, etc., cool by spraying with water.
Combat fire from a sheltered position.
|

|
Exposure
|
|
PREVENT GENERATION OF MISTS!
|
|
|
•Inhalation
|
Cough.
Drowsiness.
Headache.
Nausea.
Sore throat.
Unconsciousness.
Vomiting.
|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest.
Half-upright position.
Artificial respiration if indicated.
Refer for medical attention.
See Notes.
|
|
•Skin
|
Dry skin.
Redness.
|
Protective gloves.
|
Rinse skin with plenty of water or shower.
|
|
•Eyes
|
Redness.
|
Safety goggles.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
|
|
•Ingestion
|
(See Inhalation).
|
Do not eat, drink, or smoke during work.
|
Refer for medical attention.
|
|
Spillage Disposal
|
Storage
|
Packaging & Labelling
|
Evacuate danger area!
Consult an expert!
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 absorb in saw-dust or other combustible absorbents.
(Extra personal protection: A/P2 filter respirator for organic vapour and harmful dust).
|
Fireproof.
Separated from
incompatible materials (see Chemical Dangers and Notes).

Important Data
|
Physical State; Appearance:
COLOURLESS VISCOUS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour is heavier than air
and may travel along the ground; distant ignition possible.
Chemical Dangers:
May explosively decompose on shock, friction, or concussion.
May explode on heating.
The substance decomposes
on burning
producing nitrogen oxides.
Reacts with alkalis.
Reacts violently with strong oxidants and strong reducing agents
causing fire and explosion hazard.
Forms shock sensitive mixture with amines.
Occupational Exposure Limits:
TLV: 20 ppm, 50 mg/m3 A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2006).
MAK: skin absorption (H);
Carcinogen category: 3B
(DFG 2006).
OSHA PEL: TWA 100 ppm (250 mg/m3)
NIOSH REL: See Appendix D
NIOSH IDLH: 750 ppm See: 75525
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation and
by ingestion.
Inhalation Risk:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
irritates
the eyes,
the skin and
the respiratory tract.
The substance may cause effects on the central nervous system
, resulting in central nervous system depression.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.
The substance may have effects on the peripheral nervous system, kidneys and liver
, resulting in impaired functions.

Will turn shock-sensitive if contaminated with acids, bases, metal oxides, hydrocarbons and other combustible materials.
Combustion in a confined space may turn into detonation.
The odour warning when the exposure limit value is exceeded is insufficient.
