Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
In case of skin contact
Remove contaminated clothes. Rinse skin with plenty of water or shower.
In case of eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
If swallowed
Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Rest. Refer for medical attention .
4.2 Most important symptoms/effects, acute and delayed
Harmful if swallowed, inhaled, or absorbed through skin. Extremely destructive to mucous membranes, upper respiratory tract, skin, and eyes. Inhalation may be fatal as a result of spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis, and pulmonary edema. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. (USCG, 1999)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
FIRST AID ... Inhalation-Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention; Skin-Remove contaminated clothes. Rinse skin with plenty of water or shower; Eyes-First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor; Ingestion-Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Rest. Refer for medical attention ... The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential.

10.3 Possibility of hazardous reactions
CombustibleHEPTANOIC ACID reacts exothermically with bases. Can react, particularly if moist, with active metals to form gaseous hydrogen and a metal salt. Such reactions are slow if the acid remains dry. Corrodes or dissolves iron, steel, and aluminum parts and containers under ordinary conditions. Reacts with cyanide salts to generate gaseous hydrogen cyanide, particuarly if moist. May generate flammable and/or toxic gases with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. Reacts with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Reacts exothermically with carbonates and bicarbonates to generate a harmless gas (carbon dioxide). Can be oxidized exothermically by strong oxidizing agents and reduced exothermically by strong reducing agents. A wide variety of products is possible. May initiate polymerization reactions; may catalyze chemical reactions.

12.2 Persistence and degradability
AEROBIC: Heptanoic acid reached 44, 61, 54, and 58% of its theoretical BOD after 2, 5, 10, and 30 days, respectively, using a domestic sewage inoculum and a heptanoic acid concn of 3.1 ppm(1). Heptanoic acid, present at an initial concn of 500 ppm, was degraded 24.6, 36.1, and 49.2% of its theoretical BOD after 72 hours, by activated sludge obtained from three different treatment plants(2). In a Warburg test using an activated sludge inoculum acclimated to phenol, heptanoic acid, present at a concn of 500 ppm, reached 27% of its theoretical BOD after 12 hours(3). A 99% BOD reduction was observed for heptanoic acid after 16 days using an activated sludge system operated under semi-continuous conditions(4). In Warburg respirometer tests using an activated sludge seed, heptanoic acid, present at a concn of 500 ppm, reached 12.8, 25.4, and 42.6% of its theoretical oxygen demand after 6, 12, and 24 hours incubation, respectively(5). A total organic carbon removal ratio of 96% was observed for heptanoic acid using a non-acclimated activated sludge and an initial heptanoic acid concn of 100 mg total organic carbon/L(6).
12.3 Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for heptanoic acid(SRC), using a log Kow of 2.42(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 undissociated heptanoic acid is estimated as 490(SRC), using a log Kow of 2.42(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that undissociated heptanoic acid is expected to have moderate mobility in soil. The pKa of heptanoic acid is 4.8(4), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
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.
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.
