TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Highly flammable.  NO open flames, NO sparks and NO smoking.  Use powder, foam, carbon dioxide. 
EXPLOSION Vapour/air mixtures are explosive.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). 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   STRICT HYGIENE!   
Inhalation Confusion. Cough. Dizziness. Drowsiness. Headache. Laboured breathing. Nausea. Sore throat. Unconciousness.  Use ventilation.  Fresh air, rest. Refer for medical attention. 
Skin Dry skin. Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Vomiting. See Inhalation.  Do not eat, drink, or smoke during work.  Do NOT induce vomiting. Give nothing to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Evacuate danger area! Ventilation. 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. Do NOT wash away into sewer. Do NOT let this chemical enter the environment. Personal protection: self-contained breathing apparatus.   
EC Classification
Symbol: F, Xn, N; R: 11-38-50/53-65-67; S: (2)-9-16-29-33-60-61-62; Note: C 
UN Classification

GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-30S1262.
NFPA Code: H0; F3; R0. 
Fireproof. Separated from strong oxidants. Cool. Ventilation along the floor. 

IMPORTANT DATA
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. As a result of flow, agitation, etc., electrostatic charges can be generated. 

Chemical dangers
Reacts with strong oxidants. This generates fire and explosion hazard. Attacks some forms of plastic, rubber and coatings. 

Occupational exposure limits
TLV: 300ppm as TWA; (ACGIH 2004).
MAK: 500 ppm, 2400 mg/m³; Peak limitation category: II(2); Pregnancy risk group: D; (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 will be reached rather slowly on evaporation of this substance at 20°C. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. Exposure to high concentrations of vapour could cause lowering of consciousness. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The liquid defats the skin.
