FURFURAL ICSC: 0276
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOW LIQUID, WITH CHARACTERISTIC ODOUR. TURNS RED-BROWN ON EXPOSURE TO AIR AND LIGHT.

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
The substance polymerizes under the influence of acid(s) or base(s) with fire or explosion hazard. Reacts violently with oxidants. Attacks many plastics.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 2 ppm as TWA; (skin) A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: skin absorption (H); Carcinogen category: 3B; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin. The substance may have effects on the liver.
