TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Water spray, powder , foam carbon dioxide .
EXPLOSION Above 43C explosive vapour/air mixtures may be formed.
Above 43C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep cylinder cool by spraying with water.
EXPOSURE


 •INHALATION Cough. Dizziness. Headache. Nausea. Sore throat.
Ventilation, local exhaust, and 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 Vomiting. (Further see Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Ventilation. 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. Personal protection: filter respirator for organic gases and vapours.
Fireproof. Separated from strong oxidants, strong bases, strong reducing agents . Well closed.

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.

CHEMICAL DANGERS:
Reacts with oxidants and strong reducing agents and strong bases causing fire hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 10 ppm as TWA; (ACGIH 2008).
EU OEL: 10 ppm, 53 mg/m as TWA; 20 ppm, 107 mg/m as STEL. (EU 2000).
OSHA PEL: TWA 25 ppm (130 mg/m3)
NIOSH REL: TWA 25 ppm (130 mg/m3)
NIOSH IDLH: 100 ppm See: 541855


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

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes , the skin and the respiratory tract . The substance may cause effects on the central nervous system . Exposure far above the OEL may result in unconsciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin.

ENVIRONMENTAL
DATA

N O T E S
Explosive limits are unknown in literature, although the substance is flammable and has a flash point <61C. The odour warning when the exposure limit value is exceeded is insufficient.
