A potential health hazard from 4,4-methylene-bis(2-chloroaniline) (MOCA-R) and toluene-2,4-diisocyanate (TDI) (584849) is determined to exist in the Snowmobile Track Department of the Gates Rubber Company (SIC-3011), Denver, Colorado. TDI airborne levels are found to exceed the Federal Standard, and wipe samples taken throughout the department indicate contamination with MOCA-R. Recommendations include reduction of airborne concentrations of TDI below 0.12 milligram per cubic meter. Any exposure to MOCA-R is considered potentially hazardous as the substance is a suspected carcinogen.
