|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Highly flammable. Vapour/air mixtures are explosive. Risk of fire and explosion. See Chemical Dangers.||NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools. Prevent build-up of electrostatic charges (e.g., by grounding).||Use foam, water spray, carbon dioxide, powder. In case of fire: keep drums, etc., cool by spraying with water.|
|AVOID ALL CONTACT!|
|SYMPTOMS||ACUTE HAZARDS||FIRST AID|
|Inhalation||Dizziness. Drowsiness. Headache. Nausea. Shortness of breath. Convulsions. Unconsciousness.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Refer for medical attention.|
|Skin||MAY BE ABSORBED! Dry skin. Redness. Pain. Further see Inhalation.||Protective gloves. Protective clothing.||Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .|
|Eyes||Redness. Pain.||Wear face shield 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||Abdominal pain. Sore throat. Vomiting. Further see Inhalation.||Do not eat, drink, or smoke during work.||Rinse mouth. Do NOT induce vomiting. Refer for medical attention .|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT wash away into sewer. Do NOT let this chemical enter the environment. 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.||

|PHYSICAL & CHEMICAL INFORMATION|
Physical State; Appearance
|EXPOSURE & HEALTH EFFECTS|
Routes of exposure
Effects of short-term exposure
Effects of long-term or repeated exposure
|Occupational exposure limits|
TLV: 0.5 ppm as TWA; 2.5 ppm as STEL; (skin); A1 (confirmed human carcinogen); BEI issued.
MAK: carcinogen category: 1; germ cell mutagen group: 3A; skin absorption (H).
EU-OEL: 3.25 mg/m3, 1 ppm as TWA.
|The substance is toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment.|
|Use of alcoholic beverages enhances the harmful effect.
Depending on the degree of exposure, periodic medical examination is suggested.
The odour warning when the exposure limit value is exceeded is insufficient.
Benzene causes acute myeloid leukaemia/acute non-lymphocytic leukaemia. Also, a positive association has been observed between exposure to benzene and acute lymphocytic leukaemia, chronic lymphocytic leukaemia, multiple myeloma, and non-Hodgkin lymphoma.
