If swallowed
Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .
4.2 Most important symptoms/effects, acute and delayed
Vapor is narcotic in action and irritating to respiratory passages. Liquid is irritating to skin and eyes. (USCG, 1999)
4.3 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. /Higher alcohols (>3 carbons) and related compounds/

10.3 Possibility of hazardous reactions
Highly flammable liquid and vapor.The vapour mixes well with air, explosive mixtures are easily formed.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].

12.2 Persistence and degradability
AEROBIC: t-Butyl alcohol, present at 100 mg/L, achieved 2.5% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). The biodegradation half-life of t-butyl alcohol was reported to range from about 28 to 180 days in aerobic water and 100 to 500 days in anaerobic water(2). t-Butyl alcohol reached 1% of its theoretical BOD using a sewage sludge during a 5 day incubation period(3). Using a river die-away test, t-butyl alcohol achieved 4% of its theoretical BOD in 12 days(4). t-Butyl alcohol, present at 50 mg/L, achieved 7% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(5). Approximately 96% dissolved organic carbon was removed over a 6 day incubation period using the Zahn-Wellens test, meant to simulate degradation at an industrial sewage treatment plant(5). Using an activated sludge in a prolonged closed bottle biodegradation test, t-butyl alcohol was degraded 10, 63 and 67% in 28, 42 and 56 days, respectively(6). Biodegradation of t-butyl alcohol in unamended soils collected at different depths had rates of <0.01 to 0.15 mg/L/day/gram dry soil(7).
12.3 Bioaccumulative potential
BCF values of <5 were reported for carp exposed to 6 ug/L of t-butyl alcohol during a 6 week incubation period(1). According to a classification scheme(2), this BCF suggests bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
The Koc of t-butyl alcohol has been reported as 37 (log Koc 1.57)(1-2). According to a classification scheme(3), this Koc value suggests that t-butyl alcohol is expected to have very high mobility in soil.
12.5 Other adverse effects
