TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use foam, dry powder, carbon dioxide. 
EXPLOSION Above 56°C explosive vapour/air mixtures may be formed.  Above 56°C use a closed system and ventilation.   
 
EXPOSURE      
Inhalation Burning sensation. Cough. Chest tightness. Nausea. Vomiting.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin Burning sensation. Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain. Watering of the eyes.  Wear 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 refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.   

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: chemical protection suit including self-contained breathing apparatus. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.   
EC Classification
 
UN Classification
UN Hazard Class: 3; UN Pack Group: III 
GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-30GF1-III.  Separated from oxidants. 

IMPORTANT DATA
Physical State; Appearance
PALE YELLOW LIQUID WITH PUNGENT ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces sulfur oxides. Reacts with oxidants. 

Occupational exposure limits
TLV: 0.5ppm as TWA; (SEN); (ACGIH 2008).
MAK: 2 ppm, 12 mg/m³; Peak limitation category: I(1); (DFG 2008). 

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion. 

Inhalation risk
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. 

Effects of long-term or repeated exposure
