Methods and materials for containment and cleaning up
AEROBIC: In a 5-day incubation study using an activated sludge seed from a municipal sewage treatment plant, 28.0% of initial 1-hexadecanol was mineralized (CO2 measurement)(1). A theoretical BOD of 0% was observed using the AFNOR (the French norm procedure) screening test and a 5-day incubation period(2). In standard 5-day BOD tests using emulsified 1-hexadecanol, 30-60% of initial 1-hexadecanol was oxidized(3). In studies designed to examine the biodegradability of 1-hexadecanol in thin films (monolayer) on water surfaces, it was found that biological destruction of the monolayer resulted in measurable consumption of the material with all substrates that were tested; substrates included 2% settled domestic sewage in BOD dilution water, 50% Ohio River water + 50% BOD dilution water, water from a stock pond near San Antonio, TX, and other combinations of BOD dilution water and mineral supplements; oxidation rates varied with substrates; oxidation rates varied from 6.2 to 14.3% over incubation periods of 20 to 48 days(3). In Warburg respirometer tests using activated sludge and 500 mg/L of 1-hexadecanol (well above its aqueous solubility), the theoretical oxygen demand was only 0.4% after a 12-hr incubation period(4). In static culture tests examining the disappearance of 1-hexadecanol in seeded media as compared to unseeded control media over a 10-day incubation period, almost none disappeared from the control media while nearly 20% disappeared from the seeded media; in shake flask tests using seeded media and a fine granular form of 1-hexadecanol, the initial 1-hexadecanol concn of 100 mg/L decreased to only 0.25 mg/L after 30 days of incubation; the overall results of the study concluded that given sufficient time in contact with adapted microbial species under conditions otherwise non-limiting, the complete disappearance of 1-hexadecanol as an identifiable molecular species will occur; one limiting condition is the relative insolubility of 1-hexadecanol in water; it was found that microbial growth occurs more rapidly when the 1-hexadecanol substrate is added in dissolved form (eg hexane solution)(5).
SECTION 7: Handling and storage
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
In general, materials which are toxic as stored or which can decompose into toxic components ... should be stored in a cool, well-ventilated place, out of direct rays of the sun, away from areas of high fire hazard, and should be periodically inspected ... incompatible materials should be isolated from each other.

Bioaccumulative potential
In a 3-day static exposure study using golden orfe fish (Leuciscus idus melanotus), a 1-hexadecanol bioconcentration factor (BCF) of 56 was observed(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC), provided the compound is not metabolized by the organism(SRC). A 24-hr BCF of 17000 was observed in algae (Chlorella fusca)(1).
Mobility in soil
The Koc of 1-hexadecanol is estimated as 25,000(SRC), using a water solubility of 4.122X10-2(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1-hexadecanol is expected to be immobile in soil.
Other adverse effects

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.
