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
Fresh air, rest. Refer for medical attention.
In case of skin contact
Remove contaminated clothes. Rinse and then wash skin with water and soap.
In case of eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
If swallowed
Rinse mouth. Do NOT induce vomiting. Refer for medical attention .
4.2 Most important symptoms/effects, acute and delayed
Vapors cause headache and dizziness. Liquid irritates eyes and skin. If taken into lungs, causes severe coughing, distress, and rapidly developing pulmonary edema. If ingested, causes nausea, vomiting, cramps, headache, and coma; can be fatal. Kidney and liver damage can occur. (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 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. /Aromatic hydrocarbons and related compounds/
5.Fire-fighting measures

12.2 Persistence and degradability
AEROBIC: 3-Xylene is degraded in standard biodegradability tests using a variety of inocula including sewage, activated sludge and seawater(1-4). Using a respirometric test, 91.8% biodegradation of 3-xylene, initially at 100 mg/L, was measured in 13 days with a lag period of 2 days(5). Half-lives of >97 and 24 days were reported for the biodegradation of 3-xylene in Texas and Oklahoma aquifers, respectively(6). Up to 0.4 mM 3-xylene was rapidly mineralized to CO2 in a laboratory aquifer column operated under denitrifying conditions; the degradation rate constant under continuous flow conditions was >0.45/hr(7). Xylene (mixed isomers), present at 100 mg/L, reached 100% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test which classified xylene as readily biodegradable(8). Using OECD Guideline 301F (Ready Biodegradability: Manometric Respirometry Test) with a mixture of sewage, soil and natural water inoculum, 3-xylene reached 98% of its O2 consumption in 28 days which classified 3-xylene as readily biodegradable(9).
12.3 Bioaccumulative potential
A BCF value of 14.8 was measured in goldfish exposed to 3-xylene at 1 mg/L(1). According to a classification scheme(2), this BCF value suggests the potential for bioconcentration in aquatic organisms is low(SRC). BCF values of 23.4 for eels(3) and 6 for clams(4) have been measured. A mean concentration of 21.7 mg/kg was measured in the muscles of eels (Aguilla japonica) exposed to sea water containing 14.1 mg/kg 3-xylene and 13.1 mg/kg 2-xylene(5). Rainbow trout (Oncorhynchus mykiss) exposed to xylene (emulsified in aquatic weed control) for 56 days in a flow-through system had a maximum BCF of 25.9(6).
12.4 Mobility in soil
A Koc value of 166 was measured for 3-xylene using sandy aquifer materials with an foc ranging from 0.0002 to 0.0225(1). Measured Koc values in soil have been reported to be 182(2), 166 and 275(3). According to a classification scheme(3), these Koc values suggest that 3-xylene is expected to have moderate mobility in soil. A Kp value (equilibrium-sorption coefficient) of 0.049 was measured for 3-xylene using a Borden soil column (98% sand, 0.29% organic carbon)(5). Benzene/toluene/xylene mixtures containing 3-xylene, were added to soil columns using aquifer material from the Cohansey aquifer (90% sand; 4.4% organic matter; pH-3.8); a partition coefficient of 8.74 was measured for 3-xylene(6). Adsorption coefficient values of 0.25, 0.23, and 0.02 were measured for 3-xylene, present in a benzene/toluene/ethylbenzene/xylene mixture, on montmorillonite, illite, and kaolinite (all with low to no organic carbon present), respectively, using a batch equilibrium technique(7). More 3-xylene vapor was sorbed by air-dry than oven-dry soil (Evesham clay; air-dry soil contained 37 g organic C, 350 g clay, and 60 g water/kg oven-dry soil) at relative vapor pressures of 3-xylene exceeding 0.6; this suggests that the planar 3-xylene molecule is either readily adsorbed by interlayer sites in the air-dry soil (more sites potentially available than in oven-dry soil) or, as it is a fairly soluble molecule, that some will dissolve in the water film in air-dry soil(8). 3-Xylene has been observed to pass through soil unchanged in concentration at a dune-infiltration site on the Rhine River(9). A soil leaching column study estimated a 3-xylene Koc of 282 using a chromatographic methodology(10).

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.
