Description of first aid measures
If inhaledMove the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Rinse with pure water for at least 15 minutes. Consult a doctor.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms and effects, both acute and delayed
Liquid irritates eyes; prolonged contact with skin causes irritation. Ingestion causes irritation of gastrointestinal tract. (USCG, 1999)
Indication of any immediate medical attention and special treatment needed
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
Extinguishing media
Wear self contained breathing apparatus for fire fighting if necessary.
Specific Hazards Arising from the Chemical
Behavior in Fire: Containers may explode. (USCG, 1999)
Advice for firefighters
Wear self-contained breathing apparatus for firefighting if necessary.
Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
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 fume hood). Allow sufficient time for evaporating vapors to completely clear the hood ductwork. Burn paper in suitable location away from /combustibles/...
Precautions for safe handling
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.
Conditions for safe storage, including any incompatibilities
It must be kept away from strong oxidizing agents, oxidation catalysts, and sources of ignition and heat.

Exposure controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures
Eye/face protectionWear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

Information on basic physicochemical properties
- Physical state
Dipentene is a colorless liquid with an odor of lemon. Flash point 113°F. Density about 7.2 lb /gal and insoluble in water. Hence floats on water. Vapors heavier than air. Used as a solvent for rosin, waxes, rubber; as a dispersing agent for oils, resins, paints, lacquers, varnishes, and in floor waxes and furniture polishes.

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).
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).
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.
