Move 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.

Indication of immediate medical attention and special treatment needed, if necessary
The systemic exposure to 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexa-methylcyclopenta-gamma-2-benzopyran (HHCB) was determined ... in humans under simulated conditions of exposure. Ring 14C-labeled HHCB 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-hr 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 0.1% for HHCB. However, over the 5-day period, 19.5% of HHCB 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 22% was shown to evaporate under the conditions of exposure.

Persistence and degradability
AEROBIC: Galaxolide, present at 10 and 20 mg/L, released 0% CO2 in four weeks using a sewage inoculum at 1 drop/L and the Modified Sturm test(1). Galaxolide, present at 10.97 mg C/L, released 0% CO2 in four weeks using an effluent from a semi-continuous activated sludge (SCAS) test after 8 weeks acclimation and the OECD 302 test(1). C14-labeled galaxolide was added at 25 ug/L to freshly collected activated sludge resulting in 18% 14-CO2 recovered after 200 days; products identified were galaxolide-lactone and a galaxolide-hydroxy acid(1). Using sludge amended farm, forest, and agricultural soils sampled from New Jersey, and river sediment from the Deleware River, it was concluded that galaxolide half-life in soil is approximately 4 months(1). Therefore this compound is not expected to biodegrade rapidly(SRC).
Bioaccumulative potential
For the soil compartment, 8-week studies with earthworms (Eisenia fetida) resulted in a NOEC of 45 mg/kg for HHCB and 4-week studies with springtails (Folsomia candida) resulted in a NOEC of 45 mg/kg ... These values lead to a PNEC of 0.32 mg/kg bw ... Using mammalian studies, PNECs for fish or worm eating predators of 100 mg/kg bw HHCB can be derived. For sediment dwelling organisms, PNECs were derived by equilibrium partitioning using the aquatic PNECs. Comparing PNECs with the measured or predicted environmental exposures leads to risk characterization ratios as follows: ... soil organisms: HHCB 0.10; fish eating predators: HHCB 0.001; worm eating predators: HHCB 0.001.
Mobility in soil
The Koc of galaxolide is estimated as 38,600(SRC), using a log Kow of 5.90(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that galaxolide is expected to be immobile in soil. In soil column experiments, galaxolide was added at 0.330 ug/L to a 2.4 m soil column employing a Mohall-Laveen sandy loam soil from northwest of Pheonix, AZ(4); after percolating through the soil column over 23 days, the concentration in the column effluent was below the detection limit of 0.500 ug/L(5). Galaxolide has been found in association with suspended particulate matter collected from the Elbe River at Magdeburg, Germany during June 1996-May 1997(5). A log Koc of 4.86 has also been reported(1).
Other adverse effects

SECTION 13: Disposal considerations
Disposal methods
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.
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.
