| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Highly flammable.
|
NO open flames, NO sparks, and NO smoking.
|
Powder, AFFF, foam, carbon dioxide.
|
| EXPLOSION |
Vapour/air mixtures are explosive.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.
|
In case of fire: keep drums, etc., cool by spraying with water.
|
| EXPOSURE |
|
PREVENT GENERATION OF MISTS!
|
|
| Inhalation |
Cough. Diarrhoea. Dizziness. Headache. Nausea. Sore throat. Unconsciousness. Vomiting. Weakness. Loss of appetite.
|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest. Refer for medical attention.
|
| Skin |
Dry skin. Redness. Pain.
|
Protective gloves. Protective clothing.
|
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
|
| Eyes |
Redness. Pain.
|
Safety spectacles.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
|
| Ingestion |
Abdominal pain. (Further see Inhalation).
|
Do not eat, drink, or smoke during work.
|
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: The vapour mixes well with air, explosive mixtures are easily formed. CHEMICAL DANGERS: The substance can form explosive peroxides upon exposure to air. Reacts violently with strong oxidants and strong reducing agents. OCCUPATIONAL EXPOSURE LIMITS: TLV: 50 ppm as TWA; 75 ppm as STEL; BEI issued; (ACGIH 2004). MAK: 20 ppm, 83 mg/m³; H; Peak limitation category: I(2); Pregnancy risk group: C; (DFG 2004). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour 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 and the vapour is irritating to the eyes, the skin and the respiratory tract. Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis. The substance may cause effects on the central nervous system at high concentrations, resulting in narcosis. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. | ||
