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).

FUMARIC ACID ICSC: 1173
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.
