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

Combustible.4,4'-METHYLENEBIS(2-CHLOROANILINE) is a weak base. Undergoes an exothermic and self-sustaining decomposition reaction when exposed to heat above 392°F, In a closed container, the pressure buildup can be rapid enough to cause an explosion.

There is strong mechanistic evidence indicating that the carcinogenicity of 4,4'-methylenebis(2-chlorobenzenamine) involves a genotoxic mechanism of action that includes metabolic activation, formation of DNA adducts, and induction of mutagenic and clastogenic effects in humans. Metabolic activation to DNA-reactive intermediates occurs by multiple pathways including N-oxidation in the liver, O-acetylation in the bladder, and peroxidative activation in the mammary gland and other organs. 4,4'-Methylenebis(2-chlorobenzenamine) is carcinogenic to humans (Group 1).
No information is available on the reproductive or developmental effects of MBOCA in humans or animals.
The substance may cause effects on the blood.
This substance is carcinogenic to humans.
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
AEROBIC: 4,4'-methylenebis(2-chloroaniline), present at 100 mg/L, reached 0% of its theoretical BOD in 8 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). 4,4'-Methylenebis(2-chloroaniline) was not degraded after 6 weeks in a static system in which 2 mg/L of the compound was seeded with sludge, incubated for 7 days, and the process repeated using cultures from the original system(2). However, when the same investigators subjected the 4,4'-methylenebis(2-chloroaniline) containing water to a continuous feed activated sludge reactor, 96% of the chemical in the water was removed in 24 hours after 1 week of operation(2). Studies in pure cultures showed 4 major biodegradation products; two were identified as the N-monoacetyl, N,N'-diacetyl derivatives(3). 4,4'-Methylenebis(2-chloroaniline) is biodegraded to 4,4'-diamino-3,3'-dichlorobenzophenone in non-sterile soil(4). The rate of biodegradation in soil was not determined in part due to the irreversible binding of the chemical to the soil(4). The lack of metabolic conversion in sterile soil, as well as the higher extractable concentration present in sterile vs non-sterile soil indicate that biological degradation is occurring in the soil(4).
BCFs of 130-398 and 114-232 were reported in carp (Cyprinus carpio) exposed for 8 weeks to 4,4'-methylenebis(2-chloroaniline) at 50 and 5 ppb, respectively(1). According to a classification scheme(2), these BCF ranges suggest bioconcentration in aquatic organisms is high(SRC).
Using a structure estimation method based on molecular connectivity indices(1), the Koc of 4,4'-methylenebis(2-chloroaniline) can be estimated to be 5700(SRC). According to a classification scheme(2), this estimated Koc value suggests that 4,4'-methylenebis(2-chloroaniline) is expected to be immobile in soil(SRC).

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.
