TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Extremely 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. Use non-sparking handtools.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

 •INHALATION Cough. Sore throat.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
 •SKIN Redness.

Remove contaminated clothes. Rinse skin with plenty of water or shower.
 •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.

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. (Extra personal protection: self-contained breathing apparatus).
Fireproof. Separated from strong oxidants, acids. Cool. Well closed. Store only if stabilized.
Airtight.

PHYSICAL STATE; APPEARANCE:
CLEAR COLOURLESS LIQUID, TURNING BROWN UPON STANDING , WITH CHARACTERISTIC ODOUR.

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

CHEMICAL DANGERS:
The substance can form explosive peroxides upon contact with air. Reacts violently with oxidants and acids causing fire and explosion hazard. Fire hazard upon exposure to heat or flame.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: skin absorption (H);
Carcinogen category: 2
(DFG 2008).


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

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 irritates the respiratory tract. Inhalation of the vapour may cause lung oedema (see Notes).

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: 31.3°C
Melting point: -85.6°C
Relative density (water = 1): 0.94
Solubility in water: poor
Relative vapour density (air = 1): 2.3
Flash point: -35°C
Explosive limits, vol% in air: 2.3-14.3
Octanol/water partition coefficient as log Pow: 1.34

ENVIRONMENTAL
DATA


N O T E S

The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. 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.
Transport Emergency Card: TEC (R)-30G30

NFPA Code: H1; F4; R1;
Card has been partially updated in February 2009: see Occupational Exposure Limits,
