TYPES OF
HAZARD/
EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Highly flammable.
NO open flames, NO sparks, and NO smoking.
Powder, AFFF, foam, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools.
In case of fire: keep drums, etc., cool by spraying with water.
 
EXPOSURE


INHALATION
Ventilation, local exhaust, or breathing protection.
Fresh air, rest.
SKIN
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
EYES
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.
Rinse mouth.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Ventilation. 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.
Fireproof. Separated from strong oxidants.

UN Hazard Class: 3
UN Packing Group: II

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:
Reacts violently with oxidants causing fire and explosion hazard. Attacks plastic.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: 500 ppm; 1760 mg/m3 (as TWA) (ACGIH 1993-1994).
TLV (as STEL): 1000 ppm; 3500 mg/m3 (ACGIH 1993-1994).


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

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:


EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
PHYSICAL

 Boiling point: 60°C
Melting point: -153°C
Relative density (water = 1): 0.65
Solubility in water: none
Vapour pressure, kPa at 20°C: 23		 Relative vapour density (air = 1): 3.0
Flash point: -32°C c.c.
Auto-ignition temperature: 264°C
Explosive limits, vol% in air: 1.0-7
