TRIETHANOLAMINE ICSC: 1034
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS VISCOUS HYGROSCOPIC LIQUID OR CRYSTALS, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance is a weak base. Reacts with oxidants. The substance decomposes on burning producing toxic and corrosive fumes including nitrogen oxides.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 5 mg/m as TWA; (ACGIH 2003).
MAK: Sh; (DFG 2002).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization.
