| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
|
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.
|
|
| EXPOSURE |
|
PREVENT DISPERSION OF DUST!
|
|
| Inhalation |
Cough. Sore throat.
|
Local exhaust or breathing protection.
|
Fresh air, rest.
|
| Skin |
Redness.
|
Protective gloves.
|
Remove contaminated clothes. Rinse skin with plenty of water or shower.
|
| Eyes |
Redness. Pain.
|
Safety goggles.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
|
| Ingestion |
Abdominal cramps. Diarrhoea. Nausea.
|
Do not eat, drink, or smoke during work.
|
Rinse mouth. Give plenty of water to drink. Rest.
|
| SPILLAGE DISPOSAL | PACKAGING & LABELLING | |||||||
|
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting, then remove to safe place (extra personal protection: P2 filter respirator for harmful particles).

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: ODOURLESS, COLOURLESS CRYSTALLINE POWDER. PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: On combustion, forms irritating fumes of maleic anhydride. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes, the skin and the respiratory tract. | ||
| PHYSICAL PROPERTIES | |||
|
Sublimation point: 200°C Relative density (water = 1): 1.63 Solubility in water: 0.63 g/100 ml at 25°C |
Auto-ignition temperature: (powder) 740°C | ||
| ENVIRONMENTAL DATA | |||
|
| |||
| NOTES | |||
|
Melting point 287°C (closed capillary, rapid heating); partial carbonization and formation of maleic anhydride occur at 230°C (open vessel). Health effects of exposure to the substance have been investigated, but none has been found.
