This report covers work done at the Naval Air Rework Facility, North Island NAVAIREWORKFAC NORIS, California, during October, November, and December 1976. A study of the airborne concentrations of four toxic vapors was made at the Helicopter Blade Bonding Shop and the Electroplating Shop. The four vapors were Acetone, Toluene, Methyl Ethyl Ketone MEK, and Methyl Chloroform. An attempt was made to study a fifth toxic vapor, hydrogen cyanide, but this was unsuccessful because of the inability to calibrate the Wilks Portable Infrared Gas Analyzer MIRAN I used in all work done. Results indicate that, in general, concentrations of the above vapors are within Occupational Safety and Health Act OSHA limits for human exposure, based on a long-time 8-hour average. Occasional peaks were found where limits were exceeded. The MIRAN I is a useful, dependable vapor concentration analyzer. It should be used to study concentrations of the above vapors and other vapors of possible interest at any part of the North Island complex where humans are exposed to these vapors in the normal course of their work.
