Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .

Rinse mouth. Do NOT induce vomiting. Refer for medical attention .
Inhalation causes irritation of mucous membrane and respiratory tract; may cause nausea and vomiting. Ingestion causes irritation of mouth and stomach. Contact with eyes may cause serious injury. Contact with skin may cause burns; chemical is readily absorbed through the skin and may cause damage by this route. (USCG, 1999)
Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist respirations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary . Monitor for shock and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Activated charcoal is not effective . Do not attempt to neutralize because of exothermic reaction. Cover skin burns with dry, sterile dressings after decontamination . Organic acids and related compounds
Use water spray, dry chemical, "alcohol resistant" foam, or CO2. Use water to keep fire-exposed containers cool. On large fires, solid streams of water may not be effective.
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)
Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable containers as far as possible. Cautiously neutralize remainder with soda lime. Then wash away with plenty of water.

Land spill: Dig a pit, pond, lagoon, or holding area to contain liquid or solid material /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash or cement powder. Neutralize with agricultural lime (slaked lime), crushed limestone, or sodium bicarbonate.
NO open flames. Above 72°C use a closed system and ventilation. 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.
Separated from strong oxidants, strong bases and food and feedstuffs.Store in cool, dry, well-ventilated location, away from any area where fire hazard may be acute.

AEROBIC: At an initial concentration of 100 mg/L, n-butanoic acid displayed a 72% theoretical biological oxygen demand (BODT) after 5 hours when incubated with activated sludge(1,2). n-Butanoic acid at an initial concentration of 5 ppm displayed a BODT of 76.6% in fresh water and 72.4% in sea water after 5 days(3). n-Butanoic acid had a BODT of 17.4%, 23.8%, 26.2%, and 27.7% after 6, 12, 18, and 24 hours, respectively, when incubated with an activated sludge seed at an initial concentration of 500 ppm(4). In a screening study, n-butanoic acid displayed a 46%, 48%, and 58% BODT after 2, 10, and 30 days, respectively, using a sewage seed(5). In a screening study using a sewage seed, n-butanoic acid had a 5 day BODT of 72-78% and a 20 day BODT of 92-99%(6,7). Several other screening studies with activated sludge inoculum have shown that n-butanoic acid is amenable to biodegradation under aerobic conditions(8-10).
An estimated BCF of 3.2 was calculated for n-butanoic acid(SRC), using a log Kow of 0.79(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).
The Koc of n-butanoic acid is estimated as 64(SRC), using a log Kow of 0.79(1) and a regression-derived equation(2). Experimental Koc values for n-butanoic acid on a clastic mud (3.5% organic carbon), a lateritic muddy sand (1.3% organic carbon), and a fine carbonate sand (0.17% organic carbon) were 19.1, 27.6, and 14.7, respectively(3). According to a classification scheme(4), these estimated and experimental Koc values suggest that n-butanoic acid is expected to have very high to high mobility in soil. The percent of n-butanoic acid sorbed to a kalonite or montmorillonite clay at 22 deg C was 14.0% and 19.9% after 48 hours, respectively, which increased to 31.4% and 24.2%, respectively, after 144 hours(5). In a field study in which 100 ppm n-butanoic acid was injected underground, the retardation, relative to the linear ground-water velocity, was calculated to be 3%(6). N-butanoic acid is listed as a compound displaying an L-type adsorption isotherm, indicating that specific binding sites may be involved(7). Experimental studies in indicate that adsorption of n-butanoic acid to moist soil is dominated by attractive forces between the compound and soil and not by hydrophobic interactions(8). The pKa of n-butanoic acid is 4.82(9), indicating that this compound will primarily exist in the anion in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(10).

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.
