Description of first aid measures
If inhaledFresh air, rest. Seek medical attention if you feel unwell.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Rinse with plenty of water for several minutes (remove contact lenses if easily possible).
Rinse mouth. Rest. Do NOT induce vomiting. Seek medical attention if you feel unwell.
Most important symptoms and effects, both acute and delayed
Liquid will cause burning of the eyes and may irritate skin. (USCG, 1999)
Indication of any immediate medical attention and special treatment needed
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. Higher alcohols (>3 carbons) and related compounds
Extinguishing media
Wear self contained breathing apparatus for fire fighting if necessary.

Possibility of hazardous reactions
Combustible when it is exposed to heat or flame.DODECANOL is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

Persistence and degradability
AEROBIC: A 5-day theoretical BOD of 20% was observed for 1-dodecanol in an aerobic screening test using a sewage inoculum(1). A 5-day theoretical BOD of 23.2% was observed for 1-dodecanol in a standard BOD dilution test using a mixed microbial inoculum(2-3). A 5-day theoretical BOD of 27-29.7% was observed for 1-dodecanol in a standard BOD aerobic screening test using a sewage inoculum or an acclimated activated sludge inoculum(4); using a Warburg respirometer technique and a sewage inoculum, a 6-hr theoretical BOD of 15.2% was observed(4). Using a Warburg respirometer technique and various activated sludge inoculum, respective 6-hr, 12-hr and 24-hr theoretical BODs of 4.5, 10.1 and 13.4% were observed(5). 1-Dodecanol was found to be readily biodegraded(6).
Bioaccumulative potential
An estimated BCF of 48 was calculated in fish for 1-dodecanol(SRC), using a log Kow of 5.13(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).
Mobility in soil
Koc values of 2042-3388 were reported for 1-dodecanol in humic acid(1). According to a classification scheme(2), this Koc range suggests that 1-dodecanol is expected to have slight mobility in soil. Koc values of 2570-6574, 2337-11,184, 7700 and 16,700-17,981 were reported for 1-dodecanol in activated sludge, sediment, suspended solids and suspended solids with activated sludge, respectively(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.
