4.3 Indication of immediate medical attention and special treatment needed, if necessary/SRP:/ 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 the 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. /Poisons A and B/

AEROBIC: When seeded with a soil inoculum, 1,1'-methylenebisbenzene underwent extensive degradation in 40 days, following a 30 day lag(1). 1,1'-Methylenebisbenzene was completely degraded within 5 days in a river die-away test(2); the study found that, in general, 1,1'-methylenebisbenzene compunds having an unsubstituted phenyl ring undergo rapid primary biodegradation(2). 1,1'-Methylenebisbenzene is degraded by microorganisms isolated from sewage, water, soil, and leaves(3-5). Three metabolic pathways have been identified leading to the initial metabolic product 1,1,1',1'-tetraphenyldimethyl ether, phenylacetic acid, and benzhydrol(3). 1,1'-Methylenebisbenzene, present at 100 mg/L, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(6).
12.3 Bioaccumulative potentialUsing catfish which were exposed over an 8-week period to 1,1'-methylenebisbenzene concentrations of 0.01 mg/L and 0.1 mg/L, 1,1'-methylenebisbenzene BCF values were measured that ranged from 452 to 1190(1). According to a classification scheme(3), this BCF range suggests the potential for bioconcentration in aquatic organisms is high to very high(SRC).
12.4 Mobility in soilUsing a structure estimation method based on molecular connectivity indices(1), the Koc of 1,1'-methylenebisbenzene can be estimated to be 9160(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1,1'-methylenebisbenzene is expected to be immobile in soil.

13.Disposal considerations 13.1 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.
Contaminated packagingContainers 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.
