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. Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.

6.3 Methods and materials for containment and cleaning up

Pick up and arrange disposal. Sweep up and shovel. Keep in suitable, closed containers for disposal.

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.

10.3 Possibility of hazardous reactions

MODERATE FIRE RISK.The vapour is heavier than air and may travel along the ground; distant ignition possible.METHYL ISOBUTYL CARBINOL 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 compound is incompatible with strong oxidizers (NIOSH, 2016).

12.1 Toxicity

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

A percent theoretical BOD of 84% was observed after 5 days in screening tests using the standard dilution technique and effluent from a biological sanitary waste treatment plant as inoculum(1). A percent theoretical BOD of 43% was observed after 5 days in screening tests using the standard dilution technique and acclimated sewage as inoculum(2). Tests using acclimated mixed microbial cultures as inoculum gave a percent theoretical BOD of 56% after 5 days(3). In screening tests using filtered, settled domestic wastewater as inoculum, the observed percent theoretical BOD of 50%, 72%, 90% and 94% were observed after 5, 10, 15, 20 days, respectively(4). In screening tests using activated sludge in a medium containing 100 ppm urea and approximately 16,000 ppm ethyl alcohol, the observed rate constant of disappearance of 4-methyl-2-pentanol was 0.432/hr which corresponds to a half-life of 17 hr(5). The results of these laboratory screening tests indicate that 4-methyl-2-pentanol is readily biodegradable under the conditions used in the experiments(SRC). No information regarding biodegradation in natural media was found(SRC).

12.3 Bioaccumulative potential

Based upon an experimental log Kow of 1.43(1), a BCF of 7.2 has been estimated using a recommended regression equation(2). Based upon an experimental water solubility of 1.64X10+4 mg/kg(3), a BCF of 2.6 has been estimated using a recommended regression equation(2). Based upon these estimated BCF, 4-methyl-2-pentanol will not be expected to bioconcentrate in aquatic organisms(SRC).

12.4 Mobility in soil

Based upon an experimental log Kow of 1.43(1), a Koc of 143 has been estimated using a recommended regression equation(2). Based upon an experimental water solubility of 1.64X10+4 mg/kg(3), a Koc of 21 has been estimated using a recommended regression equation(2). Based upon these estimated Koc, 4-methyl-2-pentanol will be expected to exhibit high to very high mobility in soil(4). 4-Methyl-2-pentanol, therefore, may leach through soil to groundwater if it does not volatilize or biodegrade first(SRC).

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. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
