• Description:
  Breathing zone and environmental samples were analyzed for 4,4'- methylene-bis-(2-chloroaniline) (38483486) (MBOCA) at Steinmetz and Sons Machinery Company (SIC-2821), Moscow, Pennsylvania in September, 1984. The evaluation was requested to assess the effectiveness of a procedure for reducing worker exposures to MBOCA. Urine samples were collected from eight workers to determine actual absorbed doses. No airborne MBOCA was detected. The NIOSH standard for MBOCA is 3 micrograms per cubic meter. Two of 18 wipe samples, taken on the surface of the MBOCA melting pots, contained 136 and 1,490 micrograms MBOCA. No MBOCA contamination on worker hands was detected. All urine samples contained detectable concentrations of MBOCA, ranging up to 37 milligrams per liter (microg/l). The California Occupational Safety and Health Administration standard for urinary MBOCA is 100microg/l. The authors conclude that MBOCA exposures at the facility are below current exposure criteria. The data suggests that exposure concentrations can be reduced further. Recommendations include issuing work clothing (including underwear) that is not to be worn home, requiring employees to shower at the end of a work shift, and improving the ventilation system.
