Refer for medical attention .
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention .
Most important symptoms/effects, acute and delayed
Irritating to skin, eyes and mucous membranes. Repeated exposure of skin may cause dermatitis due to defatting action. Chronic inhalation of vapors or mist may result in damage to lungs, liver, and kidneys. Acute vapor exposures can cause symptoms ranging from coughing to transient anesthesia and central nervous system depression. (USCG, 1999)
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 as 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. Benzene and Related Compounds

May react violently with dimethyl sulfoxide. Reacts vigorously with oxidizing agents. Attacks some forms of plastic, rubber and coatings. Forms a shock sensitive solvated salt with silver perchlorate. (NTP, 1992).

Persistence and degradability
Information ... concerning the biodegradation potential of chlorobenzene indicates that this compound will ... eventually degrade, but not at an environmentally important rate unless the microorganisms present are already growing on another hydrocarbon source.
Bioaccumulative potential
BCF values of 4.3 to 39.6 and 3.9 to 22.8 were measured for chlorobenzene in carp (Cyprinus carpio) at chemical concentrations of 0.15 and 0.015 mg/L, respectively(1). A log BCF of 2.65 has been reported for chlorobenzene in fathead minnows(2) that corresponds to a BCF of 450(SRC). A BCF of 41 was measured in bluegill fish (Lepomis macrochirus) over a 14-day exposure period(3). According to a classification scheme(4), these BCF values suggest the potential for bioconcentration in aquatic organisms ranges from low to high, provided the compound is not metabolized by the organism(SRC). Dissolved organic matter that is present in interstitial water may greatly reduce the amount of a chemical that is available for accumulation(5). In one set of experiments, midge larvae were found to accumulate higher tissue-to-sediment ratios of chlorobenzene from a low-organic content sediment than from a high-organic content sediment(5). BCFs of 0.25 (from sediment), 11 (from interstitial water), and 10 (overlying water) were measured for midge larvae exposed to chlorobenzene under equilibrium exposure conditions(5). BCFs of 0.15 (from sediment), 310 (from interstitial water), and 5 (from overlying water) were measured for midge larvae exposed to chlorobenzene sorbed to high-organic content sediment under nonequilibrium exposure conditions(5). BCFs of 0.72 (from sediment), 18 (from interstitial water), and 2,187 (from overlying water) were measured for midge larvae exposed to chlorobenzene sorbed to low-organic content sediment under nonequilibrium exposure conditions(5).
Mobility in soil
Koc values of 313.1 and 146.5 were measured on Captina silt loam (1.49% organic carbon) and McLaurin sandy loam, (0.66% organic carbon), respectively(1). Equilibrium sorption constant (Ks) values of 0.295 and 0.09 were determined in Eustis fine sand (13 g/kg clay, 32 g/kg silt, 955 g/kg sand, 3.9 g/kg organic carbon) and Tampa (6 g/kg clay, 23 g/kg silt, 971 g/kg sand, and 1.3 g/kg organic carbon) soils, respectively(2); corresponding Koc values are 76 and 69(SRC). Equilibrium sorption coefficients of 0.014 and 10.20 were measured on Borden (98% sand, 1% silt, 1% clay, 0.29% organic carbon) and Mt. Lemmon (60.3% sand, 24.0% silt, 15.7% clay, 12.6% organic carbon) soils, respectively(3); corresponding Koc values are 4.8 and 81(SRC). According to a classification scheme(4), these Koc values suggest that chlorobenzene is expected to have moderate to very high mobility in soil(SRC). The sorption isotherm for chlorobenzene onto muck soil (49.0% organic carbon) was linear(5). A Kd value of 166.34 was measured for chlorobenzene using dewatered activated sludge (18% solids) that had been dried and sieved; 3.28% of the chlorobenzene was desorbed during the desorption phase of the experiment(6). Partition coefficients of 0.35, 0.33, and 0.38 were measured for chlorobenzene on primary sludge, mixed liquor solids, and digested sludge, respectively(7). Sorption coefficients of 0.48 and 0.29 were measured on primary sludge and anaerobically digested sludge, respectively(8). Partition coefficients of 48 and 29 were measured in high organic carbon (14.5%) and low organic carbon (3.6%) Sherman Island sediments, respectively(9).

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.
