NIOSH 1986 Nov; :1-18
An authorized representative of the Association of Western Pulp and Paper Workers requested an investigation be made of employee exposure to diethylenetriamine (111400) (DETA), hexamethylene- diisocyanate (822060) (HDI), and other chemicals in use during the production of carbonless paper at the Boise Cascade (SIC-2641) facility in Vancouver, Washington. This facility makes paper from pulp and carbonless paper by applying the appropriate coatings to the paper. Possible exposures to biphenyl (92524) and butyl- biphenyls, formaldehyde (50000), phenol (108952), and petroleum solvents were also investigated. Medical interviews were conducted with 65 employees. All the breathing zone and area samples for DETA in the coater preparation department were lower than detectable concentrations of 0.01 and 0.07 parts per million (ppm). Concentrations of biphenyl were less than detectable concentrations of 0.02ppm. Butyl-biphenyl concentrations were 0.12 and 0.29ppm. HDI concentrations ranged from 0.7 to 4.5 micrograms/cubic meter in the breathing zone samples for coater and assistant coater operators. DETA concentrations were less than 0.06ppm. In four cases, pulmonary problems were determined which may have been related to past diisocyanate exposure. The authors recommend that workers with asthma sensitization be medically monitored and evaluated and that contact and inhalation exposures be reduced by the use of personal protective clothing and increased ventilation.
