| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Combustible.
|
NO open flames.
|
Powder, water spray, foam, carbon dioxide.
|
| EXPLOSION |
Finely dispersed particles form explosive mixtures in air.
|
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding).
|
|
| EXPOSURE |
|
PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF (PREGNANT) WOMEN!
|
|
| Inhalation |
|
Ventilation, local exhaust, or breathing protection.
|
|
| Skin |
|
Protective gloves.
|
Rinse skin with plenty of water or shower.
|
| Eyes |
|
Safety spectacles.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
|
| Ingestion |
Confusion. Headache. Nausea. Vomiting.
|
Do not eat, drink, or smoke during work.
|
Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: WHITE TO GREY POWDER, WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc. CHEMICAL DANGERS: The substance decomposes on burning producing toxic and corrosive fumes including nitrogen oxides, sulfur oxides. Reacts violently with strong oxidants. Attacks copper. OCCUPATIONAL EXPOSURE LIMITS: TLV: 2 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004). MAK: (Inhalable fraction) 2 mg/m³; sensitization of skin (Sh); Peak limitation category: II(8); Pregnancy risk group: D; (DFG 2004). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of dust and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the endocrine system, liver, nervous system and thyroid, resulting in impaired functions. Animal tests show that this substance possibly causes toxicity to human reproduction or development. | ||

|
Boiling point at 2.3kPa: 117°C Melting point: 71°C Density: 1.3 g/cm³ Solubility in water, g/100 ml: 0.02 |
Octanol/water partition coefficient as log Pow: 3.9 | ||
| ENVIRONMENTAL DATA | |||
|
The substance is toxic to aquatic organisms.
| |||
| NOTES | |||
|
In combination with alcohol the substance causes effects on cardiovascular and central nervous systems resulting in palpitation, hypotension and hyperventilation. The effects may be delayed. Do NOT take working clothes home. Antabuse and Rosulfiram are trade names. Card has been partly updated in April 2005. See section Occupational Exposure Limits. | |||
