EPA Proposes Rule on New Uses, Imports of Toluene Diisocyanates

EPA has proposed a significant new use rule (SNUR) to protect consumers and workers from new uses and imports of toluene diisocyanates, chemicals that the agency says are currently used in residual amounts in the production of polyurethanes and consumer products such as coatings, adhesives, and sealants. According to EPA, diisocyanates are well-known dermal and inhalation sensitizers in the workplace and can cause asthma, lung damage, and fatal reactions. The agency’s action plan for the chemicals focuses on the potential health effects from exposures to consumers or self-employed workers while using products containing uncured diisocyanates. 

EPA’s proposed SNUR would require manufacturers and importers to notify EPA at least 90 days prior to starting or resuming new uses of toluene diisocyanates in consumer products at levels above 0.1 percent by weight. 
The SNUR is available for public comment through March 16. For more information, visit the EPA website.
