The Environmental Protection Agency (EPA) has determined that 3,3 -dichlorobenzidine is a probable human carcinogen. The U.S. Department of Health and Human Services (DHHS) has determined that 3,3 -dichlorobenzidine and its salt may reasonably be expected to be cancer-causing substances... 

Methods for the determination of 3,3 -dichlorobenzidine and its metabolites in biological materials are smnmarized in Table 6-1. 

EPA has selected 3,3 -dichlorobenzidine and its mixtures for priority consideration for testing under the Toxic Substances Control Act (TSCA) (IRIS 1998). 

The OSHA regulation 29 CFR 1910.1003 pertains to solid or liquid mixtures containing less than 0.1 percent by weight or volume of 4-nitroWphenyl, methyl chloromethyl ether, bis-chloromethyl ether, beta-naphthylamine, benzidine, or 4-aminodiphenyl, and solid or liquid mixtures containing less than 1.0 percent by weight or volume of alpha-naphthylamine, 3,3 -dichlorobenzidine (and its salts), ethyleneimine, beta-propiolactone, 2-acetyIaminofluorene, 4-dimethylaminoazobenzene, or N-nitrosodimethylamine. 

Dry sweeping and dry mopping are prohibited for 4-nitrobiphenyl, alpha-naphthylamine, 3,3 -dichlorobenzidine (and its salts), beta-naphthylamine, benzidine, 4-aminodiphenyl, 2-acetylaminofluorene, 4-dimethylaminoazobenzene, and N-nitrosodimethylamine. 

Employees shall be required to wash hands, forearms, face, and neck on each exit from the regulated area, close to the point of exit, and before engaging in other activities. Employees exposed to 4-nitrobiphenyl, alpha-naphthylamine, 3,3 -dichlorobenzidine (and its salts), beta-naphthylamine, benzidine, 4-aminodiphenyl, 2-acetylaminofluorene, 4-dimethylamino-azobenzene, and N-nitrosodimethylamine shall be required to shower after the last exit of the day.
