|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Flammable. Above 40°C explosive vapour/air mixtures may be formed. Risk of fire and explosion on contact with many materials.||NO open flames, NO sparks and NO smoking. Above 40°C use a closed system, ventilation and explosion-proof electrical equipment.||Use alcohol-resistant foam, foam, water spray, dry powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.|
|AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!|
|Inhalation||Cough. Burning sensation. Headache. Confusion. Drowsiness. Nausea. Shortness of breath. Convulsions. Unconsciousness.||Use closed system and ventilation.||Fresh air, rest. Half-upright position. Refer immediately for medical attention.|
|Skin||MAY BE ABSORBED! Redness. Pain. Skin burns.||Protective gloves. Protective clothing.||First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. See Notes. Refer immediately for medical attention.|
|Eyes||Redness. Pain. Blurred vision. Severe burns.||Wear face shield or eye protection in combination with breathing protection.||Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.|
|Ingestion||Burns in mouth and throat. Abdominal pain. Diarrhoea. Vomiting. Shock or collapse. Further see Inhalation.||Do not eat, drink, or smoke during work. Wash hands before eating.||Rinse mouth. Give nothing to drink. Do NOT induce vomiting. Refer immediately for medical attention.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect leaking liquid in sealable non-metallic containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT absorb in saw-dust or other combustible absorbents.||

|EXPOSURE & HEALTH EFFECTS|
Routes of exposure
Effects of short-term exposure
Effects of long-term or repeated exposure
|OCCUPATIONAL EXPOSURE LIMITS|
TLV: 0.01 ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans).
EU-OEL: 0.013 mg/m3, 0.01 ppm as TWA; (skin).
MAK: skin absorption (H); sensitization of skin (SH); carcinogen category: 2
|The substance is very toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment.|
|Auto-ignition temperature varies from 24°C on a rusty iron surface to 270°C on glass surface.
The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
The odour warning when the exposure limit value is exceeded is insufficient.
Rinse contaminated clothing with plenty of water because of fire hazard.
Do NOT take working clothes home.
