4.First-aid measures
4.1 Description of necessary first-aid measures
General advice
Consult a physician. Show this safety data sheet to the doctor in attendance.
If inhaled
Fresh air, rest.
In case of skin contact
Remove contaminated clothes. Rinse skin with plenty of water or shower.
In case of eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
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
Contact with eyes is extremely irritating and may cause burns. Breathing vapors will be irritating to the nose and throat. In high concentrations, may cause nausea, dizziness, headache, and stupor. (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/
5.Fire-fighting measures
5.1 Extinguishing media
Suitable extinguishing media
Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
5.2 Specific hazards arising from the chemical
Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / Noxious)]: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. (ERG, 2016)
5.3 Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.
6.Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures
Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.
6.2 Environmental precautions
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Wash away remainder with plenty of water.
6.3 Methods and materials for containment and cleaning up
1. Remove all ignition sources. 2. Ventilate area of spill or leak. For small quantities, absorb on paper towels. Evaporate in safe place ... allow sufficient time for evaporating vapors to completely clear hood ductwork. Burn paper in suitable location away from combustible materials. Large quantities can be collected & atomized in suitable combustion chamber.
7.Handling and storage
7.1 Precautions for safe handling
Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.
7.2 Conditions for safe storage, including any incompatibilities
Fireproof. Separated from strong oxidants and aluminium.Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carfully resealed and kept upright to prevent leakage.

10.3 Possibility of hazardous reactions
Flammable in the presence of a source of ignition when the temperature is above the flash point. Keep away from heat/sparks/open flame/ hot surface. No smoking.ISOBUTANOL 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. This chemical is incompatible with strong oxidizers.

12.2 Persistence and degradability
AEROBIC: The first-order biodegradation rate constant of isobutyl alcohol using an activated sludge inoculum was reported as 1.15X10-2 hour-1(1); this corresponds to a half-life of about 2.5 days(SRC). Isobutyl alcohol, present at 100 mg/L, reached 90% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test which classifies the cpompound as readily biodegradable(2). The biodegradation half-life of isobutyl alcohol in a basic sandy silt loam from Texas was reported as 2.4 days and the half-life of isobutyl alcohol in an acidic sandy loam from Mississippi was reported as 11.3 days(3). Isobutyl alcohol reached 63% of its theoretical BOD using a sewage sludge during a 5 day incubation period(4). In a river die-away test, isobutyl alcohol achieved 58% of its theoretical BOD in 5 days(5), suggesting biodegradation will be an important fate process. OECD 301D Closed Bottle test yielded 14% degradation at day 5, 74% degradation at day 15 and 74% degradation at day 28(6). A second OECD 301D Closed Bottle test yielded 55% degradation on day 5, 73% degradation on day 15, and 75% degradation on day 30(6). The potential for biodegradation in a simulated wastewater treatment plant was examined using the OECD method 303A Coupled Units Test(6); over the course of 35 days, the DOC reduction averaged 97% suggesting that isobutyl alcohol is easily degraded in wastewater treatment plants(6).
12.3 Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for isobutyl alcohol(SRC), using a log Kow of 0.76(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 soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of isobutyl alcohol can be estimated to be 2.9(SRC). According to a classification scheme(2), this estimated Koc value suggests that isobutyl alcohol is expected to have very high mobility in soil.
12.5 Other adverse effects
no data available
13.Disposal considerations
13.1 Disposal methods
Product
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.
Contaminated packaging
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.
