4.2 Most important symptoms/effects, acute and delayedIrritation and burning of eyes, skin, and respiratory system. High concentration of vapor can cause asphyxiation. (USCG, 1999)
4.3 Indication of immediate medical attention and special treatment needed, if necessaryImmediate 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/

AEROBIC: Diethylamine, present at 100 mg/L, reached 69-89% of its Theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). In a screening study, diethylamine at 10 ppm degraded with both an activated sludge and freshwater/sediment inoculum, 59 and 38% of the Theoretical BOD was obtained after 12 days of incubation, respectively(2). Inhibition was noted at moderate concentrations and sizeable reductions in BOD were noted at 50 ppm(2). Diethylamine was degraded slowly by activated sludge even when acclimatized (53% of Theoretical BOD was achieved after 13 days)(3). However the concentration levels used in this study could not be ascertained. When added to stream water, the maximum rate of biodegradation of diethylamine was proportional to an initial amine concentration over a concentration range from several nanograms to several milligrams per liter(4). At the highest concentration studied, 10 mg/L, the half-life of diethylamine was 0.9 days(4).
12.3 Bioaccumulative potentialAn estimated BCF of 3 was calculated in fish for diethylamine(SRC), using a log Kow of 0.58(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soilUsing a structure estimation method based on molecular connectivity indices(1), the Koc of diethylamine can be estimated to be 27(SRC). According to a classification scheme(2), this estimated Koc value suggests that diethylamine is expected to have very high mobility in soil. The pKa of diethylamine is 11.09(3), indicating that this compound will exist entirely in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe 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.
Contaminated packagingContainers 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.
