• Description:
  Environmental and breathing zone samples were analyzed for 4,4'- methylenedianiline (101779) (MDA) at Smith Inland, Incorporated (SIC- 3079), Little Rock, Arkansas in July 1983. MDA was found in all air, dermal, and wipe samples. Ventilation measurements were taken in the upper level mixing rooms. None of the MDA concentrations exceeded the American Conference of Governmental Industrial Hygienists recommended standard of 0.8 milligram per cubic meter. Minimum general ventilation was detected in the vicinity of the weigh scale in the mixing room. The authors note that recent evidence indicates that an appreciable loss of MDA occurs during sampling. Air concentration data obtained may underestimate actual MDA concentrations. The authors recommend that an improved program of use of engineering controls and personal protective equipment be implemented, especially since MDA has been shown to be carcinogenic in laboratory animals. Specific recommendations include improving ventilation in the mixing room, use of natural latex gloves, identification of the emission sources of MDA generated by the heating resins, installation of local exhaust ventilation at these sources, and proper use of disposable dust respirators.
