TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Highly flammable.
NO open flames, NO sparks, and NO smoking.
Foam, alcohol-resistant foam, dry powder, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


 •INHALATION Cough. Sore throat. Dizziness. Headache.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
 •SKIN Dry skin.
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 Nausea.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Remove all ignition sources. 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. Do NOT wash away into sewer. (Extra personal protection: filter respirator for organic gases and vapours.)
Fireproof. Separated from strong oxidants, strong bases, strong acids.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour mixes well with air, explosive mixtures are easily formed.

CHEMICAL DANGERS:
Reacts with strong oxidants , strong acids and strong bases , causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 200 ppm as TWA; (ACGIH 2003).
MAK: IIb (not established but data is available) (DFG 2008).
OSHA PEL: TWA 200 ppm (950 mg/m3)
NIOSH REL: TWA 200 ppm (950 mg/m3)
NIOSH IDLH: 1700 ppm 10%LEL See: 105464


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour.

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 vapour is mildly irritating to the eyes and the respiratory tract . The substance may cause effects on the central nervous system . Exposure far above the OEL could cause lowering of consciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin.
