Exposures to benzidine congener dyes in the workplace may increase the risk of cancer in the exposed workers. In particular, dyes based on the chemical benzidine may be carcinogenic; dyes based on o-tolidine or o-dianisidine may also pose a carcinogenic risk to workers. Cancer could be caused by the dye itself, by leftover parent chemicals and impurities in the dye after its manufacture, or by chemicals resulting from breakdown of the dye in the body. The risk of cancer extends beyond the manufacture of benzidine congener dye where there is potential exposure to benzidine (a known carcinogen), o-tolidine, or o-dianisidine (suspected carcinogens). Workers who use the dye or the dyed product may also be at risk and should be well protected.

The National Institute for Occupational Safety and Health (NIOSH) has developed this publication to alert supervisors, workers, safety committees, and safety directors to these hazards as well as to suggest the necessary protective measures. To "aid in determining whether or not benzidine congener dyes are being used in a particular setting, Appendix A lists many of their tradenames and synonyms, grouped by their parent chemical.

10 APPENDIX A

< BCD TRADENAMES AND GENERIC NAMES I BY PARENT CHEMICAL

Distributed or formerly distributed in the United States as of August 1981

Many different tradenames and generic names are used for benzidine congener dyes. As an aid for identification, Appendix A lists tradenames and generic names used for BeDs. Dye names are listed alphabetically and grouped by their parent chemical (benzidine, o-tolidine, or o-dianisidine). All three lists should be checked for the dye name in question. Both imported and domestically produced dyes are listed.

Appendix A also lists many tradename dyestuffs that are no longer produced. These are included to (1) help workers find out whether they had been exposed to BCDs in the past, and (2) permit recognition of older inventories of discontinued dyes that could still be used.

Colour Index (C. I.) numbers and generic names are included for those dyes identified by the Toxicology Information Response Center, Oak Ridge National Laboratory as being based on benzidine, o-tolidine, or o-dianisidine. These lists are not, however, exhaustive inventories of every BCD tradename product. To ascertain whether a dye not listed is a benzidine congener dye, consult the Colour Index or contact NIOSH.

Metallized o-dianisidine-based dyes are noted by a "pound signll (#). These dyes, according to industry sources, may be less hazardous to handle than other benzidine congener dyes. Since NIOSH does not now have enough information to determine whether the commercial grade metallized dyes present less of a health hazard, the "pound signll UF) should not be construed as NIOSH support for any safety claims.
