SECTION 5: Firefighting measures
Suitable extinguishing media
Extinguish with dry chemical, alcohol foam, or carbon dioxide. Water may be ineffective on fire. Cool exposed containers with water.
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 alcohol-resistant foam, powder, 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
Remove all ignition sources. Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
Environmental precautions

Persistence and degradability
AEROBIC: In 5-day BOD tests with sewage as microbial inoculum, the oxygen consumption of n-pentyl alcohol ranged from 59 to 86.9% of the theoretical BOD(1,4-7). In a Warburg test with activated sludge as inoculum, the oxygen consumption at 1 day of incubation was 28% of the theoretical value(3). At concentrations above 300 mg/L, n-pentyl alcohol may have an inhibitory effect on the oxidative respiratory rate in the presence of activated sludge(8). The first order rate constants (at a constant microorganism concn) for biodegradation of n-pentyl alcohol in non-adapted activated sludge was 0.0285 per hr(2) corresponding to an aerobic biodegradation half-life of 1 day.
Bioaccumulative potential
An estimated BCF of 3 was calculated for n-pentyl alcohol(SRC) using a log Kow of 1.51(1) and a regression derived equation(2). Based on a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of n-pentyl alcohol is estimated as 160(SRC), using a log Kow of 1.51(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that n-pentyl alcohol is expected to have moderate 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.
