SECTION 5: Fire-fighting measures
5.1 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
Use alcohol-resistant foam. Use dry powder. Use carbon dioxide.
SECTION 6: Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures
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.
6.2 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 deg 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).
SECTION 7: Handling and storage

SECTION 10: Stability and reactivity
10.1 Reactivity
Reacts with oxidants and strong acids.
10.2 Chemical stability
no data available
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.

no data available
10.5 Incompatible materials
Can react with oxidizing materials.
10.6 Hazardous decomposition products
When heated to decomposition it emits acrid smoke and fumes.

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 deg 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
SECTION 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.
