| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire.
|
NO open flames, NO sparks, and NO smoking. NO contact with strong oxidants. NO contact with hot surfaces.
|
Powder, alcohol-resistant foam, water spray, carbon dioxide
|
| EXPLOSION |
Vapour/air mixtures are explosive. Risk of fire and explosion on contact with incompatible materials: see Chemical Dangers.
|
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 |
|
PREVENT GENERATION OF MISTS!
|
|
| Inhalation |
Cough. Sore throat. Nausea. Dizziness. Headache. Drowsiness. Vomiting. Unconsciousness. Abdominal pain.
|
Ventilation (not if powder), local exhaust, or breathing protection.
|
Fresh air, rest. Refer for medical attention immediately.
|
| Skin |
MAY BE ABSORBED!
|
Protective gloves. Protective clothing.
|
Remove contaminated clothes. Rinse skin with plenty of water or shower.
|
| Eyes |
Redness. Pain.
|
Face shield or eye protection in combination with breathing protection.
|
Rinse with plenty of water (remove contact lenses if easily possible).
|
| Ingestion |
(See Inhalation).
|
Do not eat, drink, or smoke during work.
|
Rinse mouth. Do NOT induce vomiting. Seek medical attention if you feel unwell

| 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. CHEMICAL DANGERS: The substance can form explosive peroxides on contact with air. Reacts with oxidants and strong acids. Reacts violently with some catalysts. OCCUPATIONAL EXPOSURE LIMITS: TLV: 20 ppm as TWA; (skin) A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2008). MAK: 20 ppm, 73 mg/m³; Peak limitation category: I(2); skin absorption (H); Carcinogen category: 4; Pregnancy risk group: C; (DFG 2008). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour and through the skin. INHALATION RISK: A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C ; on spraying or dispersing, however, much faster. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes and the respiratory tract. If swallowed the substance may cause vomiting, and could result in aspiration pneumonitis. Exposure at high levels could cause lowering of consciousness. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The liquid defats the skin. The substance may have effects on the central nervous system, kidneys, and liver. This substance is possibly carcinogenic to humans. | ||
