A survey to assess techniques to control occupational exposure to formaldehyde (50000) and methanol (67561) was conducted at the Celanese Chemical Company (SIC-2819) formaldehyde production unit at Bishop, Texas, in October 1982. Occupational exposure to formaldehyde was expected to be low since the production process was isolated and enclosed, except for the process sample, and the loading and discharge points. Other control measures included water scrubbers on the formaldehyde storage tanks, enclosed ventilation systems, natural ventilation, and the use of personal protective equipment. The results of analysis of the formaldehyde samples were considered unreliable and were discarded. Breathing zone samples of methanol showed generally low concentrations. It was noted that since methanol was produced at the facility and the necessity of unloading trucks or rail cars was eliminated, a major source of methanol exposure was eliminated. The authors conclude that the workers are not overexposed to methanol on a short or long term basis. Due to the lack of analytical data, no conclusions concerning formaldehyde exposure could be drawn; however, engineering controls appear to be effective.
