5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

/To fight fire use/ alcohol foam, carbon dioxide, dry chemical.

5.2 Specific hazards arising from the chemical

Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]: Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form. (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. Do NOT let this chemical enter the environment. Cover the spilled material with inert absorbent. Collect leaking and spilled liquid in sealable containers as far as possible.

6.3 Methods and materials for containment and cleaning up

AEROBIC: 1-Heptanol degrades fast in aerobic biodegradation screening tests(1-5). In a 5-day BOD test using acclimated mixed cultures, 56.3% of theoretical BOD was consumed(1). Other tests show 30% of theoretical BOD was expended in 5 days(2) and 28.9% of theoretical BOD was expended in 1 day using 500 ppm of 1-heptanol and an activated sludge inoculum(3). An aerobic biodegradation rate constant of 0.124 1/hr(4), which corresponds to a half-life of 0.23 days(SRC), was determined in an aerobic screening test at pH 7 and 25°C using an activated sludge inocula. In a similar screening test, the rate constant was measured to be 2.53X10-2 1/hr(5), which corresponds to a biodegradation half-life of 1.14 days(SRC).

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.

10.1 Reactivity

no data available

10.2 Chemical stability

Stable under recommended storage conditions.

10.3 Possibility of hazardous reactions

Fire hazard moderate when exposed to heat of flame; can react with oxidizing materials.HEPTANOL 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.

12.2 Persistence and degradability

AEROBIC: 1-Heptanol degrades fast in aerobic biodegradation screening tests(1-5). In a 5-day BOD test using acclimated mixed cultures, 56.3% of theoretical BOD was consumed(1). Other tests show 30% of theoretical BOD was expended in 5 days(2) and 28.9% of theoretical BOD was expended in 1 day using 500 ppm of 1-heptanol and an activated sludge inoculum(3). An aerobic biodegradation rate constant of 0.124 1/hr(4), which corresponds to a half-life of 0.23 days(SRC), was determined in an aerobic screening test at pH 7 and 25°C using an activated sludge inocula. In a similar screening test, the rate constant was measured to be 2.53X10-2 1/hr(5), which corresponds to a biodegradation half-life of 1.14 days(SRC).

12.3 Bioaccumulative potential

An estimated BCF of 21 was calculated for 1-heptanol(SRC), using a log Kow of 2.62(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

The Koc of 1-heptanol is estimated as 74(SRC), using a water solubility of 1,670 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1-heptanol is expected to have 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.
