In case of eye contactFirst rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
If swallowedRinse mouth. Refer for medical attention .
4.2 Most important symptoms/effects, acute and delayedInhalation of vapor may cause irritation of upper respiratory tract. Prolonged or excessive inhalation may result in headache, nausea, vomiting, and diarrhea. In severe cases, respiratory stimulation followed by respiratory and muscular paralysis, convulsions, narcosis and death may result. Ingestion may produce severe irritation of the gastrointestinal tract, followed by nausea, vomiting, cramps and diarrhea; tissue ulceration may result. Contact with eyes causes local irritation. Material can be absorbed through skin with anesthetic or irritant effect. (USCG, 1999)
4.3 Indication of immediate medical attention and special treatment needed, if necessaryEnhancement of elimination: Hemodialysis may enhance the elimination of benzyl alcohol and its metabolites and may also be useful to help correct severe metabolic acidosis. However, more cases involve prolonged repeated infusion, and the usefulness of dialysis in unknown.

10.2 Chemical stabilityOxidizes slowly, therefore remains stable for long time
10.3 Possibility of hazardous reactionsSlight, when exposed to heat or flame ...Attacks plastics. [Handling Chemicals Safely 1980. p. 236]. Acetyl bromide reacts violently with alcohols or water [Merck 11th ed. 1989]. Mixtures of alcohols with concentrated sulfuric acid and strong hydrogen peroxide can cause explosions. Example: an explosion will occur if dimethylbenzylcarbinol is added to 90% hydrogen peroxide then acidified with concentrated sulfuric acid. Mixtures of ethyl alcohol with concentrated hydrogen peroxide form powerful explosives. Mixtures of hydrogen peroxide and 1-phenyl-2-methyl propyl alcohol tend to explode if acidified with 70% sulfuric acid [Chem. Eng. News 45(43):73 1967; J, Org. Chem. 28:1893 1963]. Alkyl hypochlorites are violently explosive. They are readily obtained by reacting hypochlorous acid and alcohols either in aqueous solution or mixed aqueous-carbon tetrachloride solutions. Chlorine plus alcohols would similarly yield alkyl hypochlorites. They decompose in the cold and explode on exposure to sunlight or heat. Tertiary hypochlorites are less unstable than secondary or primary hypochlorites [NFPA 491 M 1991]. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence [Wischmeyer 1969].

AEROBIC: Benzyl alcohol underwent 70% of theoretical biological oxygen demand in 5 days under aerobic conditions using an acclimated mixed microbial culture(1). At an initial concentration of 250 ppm, benzyl alcohol achieved 29% of the theoretical BOD after 12 hours in a sewage sludge acclimated to this compound, and 31% oxidation in a sludge acclimated to mandelic acid(2). At an initial concentration of 500 ppm, it achieved 52%, 42%, and 43% of the theoretical BOD in 12 hours using a settled sewage sludge acclimated to phenol, benzoic acid, and catechol, respectively(2). It is listed as a synthetic organic chemical easily biodegradable by biological sewage treatment(3). Benzyl alcohol at an initial concentration of 500 mg/L was shown to undergo rapid oxygen uptake under aerobic conditions when inoculated with municipal sewage sludge(4,5). Benzyl alcohol achieved 48% of the theoretical BOD in 5 days using a sewage sludge seed(6). Benzyl alcohol underwent 60.8% degradation using an industrial sludge inoculum under aerobic conditions in 5 days(7). Benzyl alcohol, present at 100 mg/L, reached 94% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(8). An experimentally-derived first-order aerobic biodegradation rate constant of 0.05 days was reported(9), corresponding to a half-life of about 13 days(SRC).
12.3 Bioaccumulative potentialAn estimated BCF of 1.4 was calculated in fish for benzyl alcohol(SRC), using a log Kow of 1.10(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 soilExperimental Koc values for benzyl alcohol were <5 for three different soils; Apison (0.11% organic carbon), Fullerton (0.06% organic carbon), and Dormont (1.2% organic carbon)(1). An experimental Koc of 15 was determined for benzyl alcohol on a red-brown Australian soil (1.09% organic carbon)(2,3). A log Koc of 1.43 has also been reported(4). According to a classification scheme(5), these Koc values suggest that benzyl alcohol is expected to have very high mobility in soil.

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.
