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.
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.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN Redness. Pain.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
•EYES Redness. Pain.
Safety goggles, 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 Burning sensation.
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

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 wash away into sewer. (Extra personal protection: filter respirator for organic gases and vapours.)
Fireproof. Separated from acids, bases and oxidants . Cool. Keep in the dark. Store only if stabilized.

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

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible.

CHEMICAL DANGERS:
The substance can presumably form explosive peroxides. The substance may polymerize under the influence of acid(s) , base(s) , amines and oxidants with fire or explosion hazard. The substance decomposes on burning producing toxic gases and irritating fumes .

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 20 ppm as TWA; (ACGIH 2003).


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

INHALATION RISK:
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The vapour of the substance is irritating to the eyes and the respiratory tract. The substance is severely irritating to the eyes and the skin.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: 49°C
Melting point: -81°C
Relative density (water = 1): 0.8
Solubility in water, g/100 ml: 20
Vapour pressure, kPa at 20°C: 31.3
Relative vapour density (air = 1): 2.0
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.3
Flash point: -30°C c.c.
Auto-ignition temperature: 207°C
Explosive limits, vol% in air: 2.6-17.0
Octanol/water partition coefficient as log Pow: 0.59

ENVIRONMENTAL
DATA


N O T E S

Check for peroxides prior to distillation; eliminate if found. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
