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.

Indication of any immediate medical attention and special treatment needed
Gastrointestinal decontamination. Since there is a high risk of aspiration pneumonia, induced emesis is usually considered contraindicated in these poisonings. However, spontaneous emesis may occur due to direct irritation of the gastric mucosa. If the patient is seen within an hour of ingestion and a large amount has been ingested, gastric emptying by intubation and lavage may be considered . However, some studies have suggested greater rates of complications with lavage than with ipecac-induced emesis. There is no evidence that activated charcoal is helpful in these poisonings. ...

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.

Persistence and degradability
AEROBIC: Utilizing both batch and continuous digesters, 99% removal of alpha-terpineol (initial concentration of 3.86 ppm) was reported when it was incubated for 168-192 hr under aerobic conditions using sewage inoculum in a biological treatment study(1). At a high initial concentration of 4000 ppm, alpha-terpineol showed no biodegradation after about 23 days under aerobic conditions when added to 50 ml of mineral salts medium and 0.2 ml of radioactive waste trench leachate inoculum(2). alpha-Terpineol, present at 100 mg/L, reached 84.6% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(3). alpha-Terpineol readily degraded in forest soil inoculum at a rate of >0.10 mg/L/hr under aerobic conditions(4).
Bioaccumulative potential
An estimated BCF of 40 was calculated in fish for alpha-terpineol(SRC), using a log Kow of 2.98(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of alpha-terpineol can be estimated to be 80(SRC). According to a classification scheme(2), this estimated Koc value suggests that alpha-terpineol is expected to have high mobility in soil.

Disposal methods
ProductThe 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.
