FIRE FIGHTING
FIRE Combustible.
NO open flames.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Above 96°C explosive vapour/air mixtures may be formed.
Above 96°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. Cough. Burning sensation.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
SKIN Dry skin. Redness.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
EYES Redness. Pain.
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 covered containers. Wash away spilled liquid with plenty of water (extra personal protection: filter A).
Separated from strong oxidants.

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

PHYSICAL DANGERS:


CHEMICAL DANGERS:
Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: 25 ppm; 121 mg/m3 ceiling (ACGIH 1995-1996).


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

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system. Exposure at high concentrations could cause lowering of consciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis.
