SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Give one or two glasses of water to drink.
Most important symptoms/effects, acute and delayed
Liquid may irritate eyes and skin. (USCG, 1999)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Organic bases/amines and related compounds/

SECTION 10: Stability and reactivity
Reactivity
The substance is a weak base. Reacts with oxidants. Decomposes on burning. This produces toxic and corrosive fumes including nitrogen oxides.
Chemical stability
Stable under recommended storage conditions.
Possibility of hazardous reactions
Fire hazard: Combustible liquid when exposed to heat or flame.TRIETHANOLAMINE is an aminoalcohol. Neutralize acids to form salts plus water in exothermic reactions. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides. Reacts violently with strong oxidants. [Handling Chemicals Safely 1980. p. 928].
Conditions to avoid
no data available
Incompatible materials
Incompatible materials: Acids, oxidizing agents.
Hazardous decomposition products

- Toxicity to daphnia and other aquatic invertebrates: EC50 - Ceriodaphnia dubia - 609.88 mg/L - 48 h.

Persistence and degradability
AEROBIC: Triethanolamine, present at 50 ppm, was biodegraded 70% ThOD (theoretical oxygen demand) in 10 days in a river die-away test using acclimated Kanawha River water as seed and sewage as inoculum(1). In a BOD test in water using a sewage inoculum, triethanolamine added at an initial concentration 2.5 ppm and run for 5, 10, 15 and 20 days exhibited 0, 0.8, 3.5 and 6.8% ThOD, respectively(2). Another BOD test in water using sewage inoculum incubated for 20 days resulted in 66% ThOD for triethanolamine(3). Using synthetic sea water and sewage inoculum, a 20 day run showed 69% ThOD for triethanolamine(3). Using effluent from a biological sanitary waste treatment plant as an inoculum, triethanolamine degradation was 5% ThOD (unadapted) and 28% ThOD (adapted) in a 5 day test(4). Triethanolamine, present at 500 ppm, added to BOD water with an activated sludge inoculum and acclimated for 15 days resulted in 22% ThOD after a 10 day test period(5).
Bioaccumulative potential
BCFs of <0.4 and <3.9 were reported using carp (Cyprinus carpio) which were exposed to respective concentrations of 2.5 and 25 ppm of triethanolamine over a 6-week period(1). According to a classification scheme(2), these BCFs suggest bioconcentration in aquatic organisms is low.
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of triethanolamine can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that triethanolamine is expected to have very high mobility in soil. The pKa of triethanolamine is 7.76(3), indicating that this compound will partially exist in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
