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
Absorption, Distribution and ExcretionThe systemic exposure to 7-Acetyl-1,1,3,4,4,6-hexamethyl-1,2,3,4-tetrahydronaphthalene (AHTN) was determined ... in humans under simulated conditions of exposure. Ring 14C-labeled AHTN was applied in alcoholic solutions without occlusion to three male volunteers at concentrations approximating that which might be encountered in a typical cologne type product. After a 6-h period, all material was removed from the surface of the skin. Blood, feces and urine were collected over a 5-day period. For both materials, levels in blood and plasma were below limits of detection at all times. Based on excretion, primarily in the urine, the total absorbed dose was approximately 1% for AHTN. However, over the 5-day period, 14.5% of AHTN was recovered from the skin in dressings over the site of application indicating that a 'reservoir' had formed in the skin but the material in the reservoir was lost, by desquamation and/or by reverse absorption, and not available systemically. A mean of 24% (AHTN) was shown to evaporate under the conditions of exposure.
Extinguishing media
Use dry chemical, carbon dioxide or alcohol-resistant foam.
Specific Hazards Arising from the Chemical
no data available
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
Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
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
Store the container tightly closed in a dry, cool and well-ventilated place. Store apart from foodstuff containers or incompatible materials.

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: Tonalide, present at 30 mg/L, released 0% theoretical BOD in four weeks using an activated sludge inoculum at 100 mg/L and the Japanese MITI test(1). No oxidation occurred after 28 days using adapted industrial sludge with respirometric method(1). No CO2 was released after 28 days using a sealed vessel with activated sludge adapted for 8 weeks or using sewage effluent and a modified Strum test after 28 days(1). Tonalide was degraded 80% in 3 wks by the fungus Aureobasidium pollulans and was totally degraded in 6 days by Phanerochaete chrysosporium(1).
Bioaccumulative potential
An average BCF of 1,069 was given for eel (Anguilla anguilla) and 600 for zebra fish (Brachydonio rerio)(1). A BCF was given for bluegill sunfish (L. Macrochirus) as 597(2). According to a classification scheme(3), these BCF suggest the potential for bioconcentration in aquatic organisms is high to very high(SRC). Tonalide had a BCF of 50 in midge larvae (Chironomus riparius) and 6918 in worms (Lumbriculus variegatus)(4).
Mobility in soil
Measured Koc values for tonalide are 9,550 L/kg(1), 6,309 L/kg(2) and 63,000 L/kg(3). According to a classification scheme(4), these Koc value suggest that tonalide is expected to be immobile in soil(SRC).
Other adverse effects

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.
