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
If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.
In case of skin contact
Wash off with soap and plenty of water. Consult a physician.
In case of eye contact
Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.
If swallowed
Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.
4.2 Most important symptoms/effects, acute and delayed
Liquid irritates eyes; prolonged contact with skin causes irritation. Ingestion causes irritation of gastrointestinal tract. (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. /Turpentine, terpenes, and related compounds/

12.2 Persistence and degradability
AEROBIC: Turpentine typically contains alpha-pinene (59%), beta-pinene (24%) and other isomeric terpenes(1). A mixture consisting of 50.9% alpha-pinene and 36.8% beta-pinene biodegraded 52% after 28 days of incubation using a modified Strum test (OECD 301B) which classified the mixture as not readily biodegradable(1). Soil beneath a building, contaminated by leakage of solvents and turpentine, was sprayed with adapted microorganisms(2); monitoring over a 4-5 month period indicated that the alkylated aromatics and turpentine were being biodegraded(2). alpha-Pinene, present at 100 mg/L, reached 92% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test which classified the compound as readily biodegradable(3). alpha-Pinene compound was completely degraded within 6-8 days using soil slurries prepared from samples collected from coniferous and mixed hardwood forest watersheds(1). Using manometric respirometry tests, alpha-pinene was degraded approximately 38% over the course of a 28-day incubation(1).
12.3 Bioaccumulative potential
Turpentine typically contains alpha-pinene (59%), beta-pinene (24%) and other isomeric terpenes(1). Estimated BCF values of 714 and 258 were calculated in fish for alpha-pinene and beta-pinene respectively(SRC), using log Kow values of 4.83 and 4.16(1) and a regression-derived equation(2). According to a classification scheme(3), these BCF suggest 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
Turpentine typically contains alpha-pinene (59%), beta-pinene (24%) and other isomeric terpenes(1). Using a structure estimation method based on molecular connectivity indices(2), the Koc of alpha- and beta-pinene can be estimated to be 1000(SRC). According to a classification scheme(3), this estimated Koc value suggests that alpha- and beta-pinene are expected to have low 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.
