TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable.  NO open flames, NO sparks and NO smoking.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION Above 26°C explosive vapour/air mixtures may be formed.  Above 26°C use a closed system, ventilation and explosion-proof electrical equipment.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE      
Inhalation Sore throat.  Use ventilation.  Fresh air, rest. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.  Airtight. 
EC Classification
 
UN Classification
UN Hazard Class: 3; UN Pack Group: III 
GHS Classification

Transport Emergency Card: TEC (R)-30G35.  Fireproof. Separated from strong oxidants. Cool. Keep in the dark. Well closed. Store only if stabilized. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
The substance can form explosive peroxides on exposure to air. Reacts with strong oxidants. This generates fire and explosion hazard. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour. 

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

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 81°C
Melting point: -89°C
Relative density (water = 1): 0.84
Solubility in water: none
Relative vapour density (air = 1): 2.8
See Notes.
Flash point: 26°C c.c.

NOTES
Relative vapour density: calculated value.
Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 61°C.
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
Check for peroxides prior to distillation; eliminate if found.
