TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Highly flammable.
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 acid(s) or oxidants.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools. Prevent build-up of electrostatic charges (e.g., by grounding).
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


Inhalation Cough. Drowsiness. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
Skin Dry skin. Redness. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes Redness. Pain.
Face shield, 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 Dullness. Nausea. Drowsiness. Unconsciousness.
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Ventilation. Remove all ignition sources. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Personal protection: filter respirator for organic gases and vapours.

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. As a result of flow, agitation, etc., electrostatic charges can be generated.

CHEMICAL DANGERS:
The substance can form explosive peroxides. Reacts violently with acids and oxidants causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The vapour is irritating to the eyes, the skin and the respiratory tract. 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.
PHYSICAL PROPERTIES
Boiling point: 94 C
Melting point: -6 C
Relative density (water = 1): 0.8
Solubility in water: none
Vapour pressure, kPa at 20C: 5.79
Relative vapour density (air = 1): 3.4
Relative density of the vapour/air-mixture at 20C (air = 1): 1.1
Flash point: -6 C
Octanol/water partition coefficient as log Pow: 0.7 (calculated)
ENVIRONMENTAL DATA

NOTES
Check for peroxides prior to distillation; eliminate if found. The relation between odour and the occupational exposure limit cannot be indicated. Environmental effects from the substance have not been investigated. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
