TYPES OF
HAZARD / EXPOSURE |
ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Gives off toxic fumes in a fire or explosion. Explosive.
|
NO open flames, NO sparks, and NO smoking. NO contact with hot surfaces.
|
CONSIDER EVACUATION. Water may be used on small fires. Do not attempt to extinguish large fires.
|
| EXPLOSION |
Finely dispersed particles form explosive mixtures in air. Risk of fire and explosion when shocked or exposed to heat or flame.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT expose to friction or shock. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.
|
In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.

| EXPOSURE |
|
PREVENT DISPERSION OF DUST!
|
|
| Inhalation |
Insomnia. Abdominal pain. Cough. Diarrhoea. Headache. Sore throat. Nosebleeds.
|
Local exhaust or breathing protection.
|
Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
|
| Skin |
Redness. Yellow stains of skin and hair.
|
Protective clothing.
|
Remove contaminated clothes. Rinse skin with plenty of water or shower. Wear protective gloves when administering first aid.
|
| Eyes |
Redness. Pain.
|
Safety goggles, or eye protection in combination with breathing protection if powder.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
|
| Ingestion |
Nausea. (see Inhalation).
|
Do not eat, drink, or smoke during work.
|
Refer for medical attention.
|
| SPILLAGE DISPOSAL | PACKAGING & LABELLING |
Evacuate danger area! Consult an expert! (extra personal protection: P3 filter respirator for toxic particles).

| IMPORTANT DATA | |
|
PHYSICAL STATE; APPEARANCE:
ODOURLESS, COLOURLESS TO YELLOW CRYSTALS PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: May explosively decompose on shock, friction, or concussion. The substance decomposes explosively on heating to 187°C. Reacts with some oxidants causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV: 1.5 mg/m 3 (as TWA) (ACGIH 1997). |
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on dispersion of aerosol. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the nervous system. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma. The substance may have effects on the liver, kidneys and blood. |
| PHYSICAL PROPERTIES | |
|
Melting point: 130°C
Relative density (water = 1): 1.57 Solubility in water: none Vapour pressure, kPa at 20°C: <0.1 |
Flash point: explodes in air at 187°C
