| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Flammable.
|
NO open flames, NO sparks, and NO smoking.
|
Powder, AFFF, foam, carbon dioxide.
|
| EXPLOSION |
Above 31°C explosive vapour/air mixtures may be formed.
|
Above 31°C use a closed system, ventilation, and explosion-proof electrical equipment. Prevent build-up of electrostatic charges (e.g., by grounding).
|
In case of fire: keep drums, etc., cool by spraying with water.
|
| EXPOSURE |
|
PREVENT GENERATION OF MISTS!
|
|
| Inhalation |
Dizziness. Ataxia. Drowsiness. Headache. Unconsciousness.
|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest. Refer for medical attention.
|
| Skin |
Dry skin.
|
Protective gloves. Protective clothing.
|
Remove contaminated clothes. Rinse and then wash skin with water and soap.
|
| 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 |
(See Inhalation).
|
Do not eat, drink, or smoke during work.
|
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
|
| SPILLAGE DISPOSAL | PACKAGING & LABELLING | |||||||
|
Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment. Personal protection: filter respirator for organic gases and vapours.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: As a result of flow, agitation, etc., electrostatic charges can be generated. CHEMICAL DANGERS: Reacts violently with acids and strong oxidants causing fire and explosion hazard. The substance can form explosive peroxides. OCCUPATIONAL EXPOSURE LIMITS: TLV: 50 ppm as TWA; (ACGIH 2004). MAK: 50 ppm, 250 mg/m³; Peak limitation category: II(4); skin absorption (H); Pregnancy risk group: C; (DFG 2004). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and through the skin. 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 and the skin. 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. Exposure far above the OEL may result in unconsciousness. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. | ||
