4.First-aid measures
4.1 Description of necessary first-aid measures
General advice
Consult a physician. Show this safety data sheet to the doctor in attendance.
If inhaled
Fresh air, rest. Refer for medical attention.
In case of skin contact
Rinse and then wash skin with water and soap. Refer for medical attention if skin irritation occurs.
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. Give nothing to drink. Do NOT induce vomiting. Refer immediately for medical attention. See Notes.
4.2 Most important symptoms/effects, acute and delayed
VAPOR: Not irritating to eyes, nose or throat. If inhaled, will cause coughing or difficult breathing. LIQUID: Irritating to skin and eyes. If swallowed, will cause nausea or vomiting. (USCG, 1999)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Aliphatic hydrocarbons and related compounds/
5.Fire-fighting measures
5.1 Extinguishing media
Suitable extinguishing media
For small (incipient) fires, use media such as "alcohol" foam, dry chemical, or carbon dioxide. For large fires, apply water from as far as possible. Use very larg quantities (flooding) of water applied as a mist or spray; solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water.

12.2 Persistence and degradability
AEROBIC: n-Heptane, present at 100 mg/L, reached 101% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). In a study determining the primary aerobic biodegradation of biodiesel B20 fuel, the calculated half-life of n-heptane contained in the mixture was 2.3 days using unacclimated inocula from a rainwater detention pond(2). The theoretical oxygen demand of benzene acclimated activated sludge for n-heptane was 0.7, 4.3 and 23.4% after 6, 24, and 72 hr, respectively(3). One mg of n-heptane and 1 ml of a 1:10 suspension of Hudson-Collamer silt loam soil in mineral salts media were incubated in the dark at 25°C(4). Controls without n-heptane were used to determine the net oxygen consumed(4). The average theoretical biological oxygen demand of trials for n-heptane was 28, 63, 70 and 70% after 2, 5, 10 and 20 days, respectively(4). n-Heptane (5 ml) was completely degraded 4 days after it was added to a microcosm inoculated with soil from a gasoline contaminated site(5). At intervals of 6, 12 and 24 hr, endogenous respiration was greater than that of 3 preparations of n-heptane and activated sludge from differing aeration units of sewage treatment facilities(6). n-Heptane was degraded to approximately 17% of its initial concentration (unspecified) after 2 days and 100% after 25 days, respectively, in gasoline (400 mg/L) inoculated with activated aerobic sewage sludge (100 mg dry wt/L)(7).
12.3 Bioaccumulative potential
An estimated BCF of 550 was calculated in fish for n-heptane(SRC), using a log Kow of 4.66(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not metabolized by the organism(SRC).
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of n-heptane can be estimated to be 240(SRC). According to a classification scheme(2), this estimated Koc value suggests that n-heptane is expected to have moderate mobility in soil.
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.
