EXPOSURE


INHALATION Confusion. Dizziness. Headache. Nausea. Unconsciousness. Weakness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
SKIN Redness.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
EYES Redness.
Safety goggles.
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.
Rinse mouth.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Evacuate danger area! 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. Carefully collect remainder (extra personal protection: self-contained breathing apparatus).
Separated from strong oxidants, strong bases.

UN Hazard Class: 3
UN Subsidiary Risks: 6.1

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

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on burning producing highly toxic gases including sulfur dioxide (see ICSC # 0074). Reacts with strong oxidants and strong bases.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV not established.
MAK not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin, and by ingestion.

INHALATION RISK:
No indication can be given about the rate in which a harmful concentration in the air is 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 , resulting in respiratory failure.

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

ENVIRONMENTAL
DATA
N O T E S
Flash point and auto-ignition temperature are unknown in literature. Explosive limits are unknown in literature, although the substance is combustible and has a flash point 55°C. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
