SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .
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)
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
SECTION 5: Firefighting measures
Suitable extinguishing media
Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
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)
Special protective actions for fire-fighters
Use water spray, powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
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.
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.
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.
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames, NO sparks and NO smoking. Above 28°C use a closed system, ventilation and explosion-proof electrical equipment. Handling in a well ventilated place. Wear suitable protective clothing.

SECTION 10: Stability and reactivity
Reactivity
Reacts with aluminium and strong oxidants such as chromium trioxide. This produces flammable/explosive gas (hydrogen - see ICSC 0001). Attacks some forms of plastic, rubber and coatings.
Chemical stability
Heat contributes to instability
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. (NTP, 1992)
Conditions to avoid
no data available
Incompatible materials
Contact with strong oxidizers may cause fires & explosions.
Hazardous decomposition products
When heated to decomposition it emits acrid smoke & fumes.

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).
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).
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.
Other adverse effects
no data available
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.
