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. 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.

Environmental precautions

Remove all ignition sources. 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.

Methods and materials for containment and cleaning up

1) Remove all ignition sources. 2) Ventilate area of spill or leak. 3) For small quantities, absorb on paper towels. Evaporate in a safe place (such as a fume hood). Allow sufficient time for evaporating vapors to completely clear ductwork. Burn the paper in a suitable location away from combustible materials. Large quantities can be collected and atomized in a suitable combustion chamber. n-Amyl acetate should not be allowed to enter confined space, such as a sewer, because of the possibility of explosion.

SECTION 7: Handling and storage

Precautions for safe handling

NO open flames, NO sparks and NO smoking. Above 25°C use a closed system, ventilation and explosion-proof electrical equipment. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

SECTION 10: Stability and reactivity

Reactivity

Reacts with oxidants. This generates fire and explosion hazard. Attacks many plastics.

Chemical stability

Stability during transport: stable

Possibility of hazardous reactions

Dangerous fire hazard when exposed to heat or flame .The vapour is heavier than air.AMYL ACETATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. This compound is incompatible with the following: Nitrates; strong oxidizers, alkalis & acids (NIOSH, 2016).

Conditions to avoid

no data available

Incompatible materials

Nitrates; strong oxidizers, alkalis and acids.

Hazardous decomposition products

Persistence and degradability

AEROBIC: Two screening tests gave 13 and 38% of theoretical BOD values after 5 days(1). The first test used sewage seed and 1.7-20 ppm of n-amyl acetate and the second test used 440 ppm of the chemical and 10% sewage seed(1). In a biodegradability screening test using non-acclimated sewage seed, the 5 day biological oxygen demand value for n-amyl acetate was 64 and 35% theoretical in fresh and salt water(2). After 20 days the respective values were 72 and 87%(2). The degradation kinetics of n-amyl acetate in Lake Superior harbor water was first order(3). When the water was coarsely filtered (suspended solids 5.6 mg/L), the biodegradation half-life was 10.0 days, when the water was finely-filtered (2.5 mg/L suspended solids), the half-life was 4.5 days(3). The increase in rate using finely-filtered water was attributed to the reduced level of suspended solids since the other water characteristics were comparable, no reason was offered for why this might increase the biodegradation rate(3). Using a standard BOD dilution technique and an acclimated mixed culture inoculum, a theoretical BOD of 31% was observed over a 5-day incubation period(4). Using the same test with an activated sludge inoculum, a theoretical BOD of 23% was observed over a 5-day incubation period(5). The theoretical BOD for n-amyl acetate in river water over a 20-day incubation period was 50%(6).

Bioaccumulative potential

An estimated BCF of 15 was calculated in fish for n-amyl acetate(SRC), using a log Kow of 2.3(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 n-amyl acetate can be estimated to be 34(SRC). According to a classification scheme(2), this estimated Koc value suggests that n-amyl acetate is expected to have very high mobility in soil.

Other adverse effects

no data available

SECTION 13: Disposal considerations

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.
