A survey was conducted at Optifab, Incorporated (SIC-7379), in Phoenix, Arizona, on October 31, 1981 as part of a study of control technology in integrated circuit manufacturing facilities. The walkthrough survey was focused on mask production operations. Process description, specific unit operations, monitoring systems, and chemical storage programs were reviewed. The company employed about 80 people, less than 50 percent of whom were employed in photo mask production. Chemicals used for photo work were stored in a room that was separate from the process area. No ventilation was provided to the storage area. No monitoring for chemical or physical agents was performed. There was no formal safety program. Industrial hygiene, nursing, and medical services were contracted from outside as needed. Personal protective equipment, including safety goggles, rubber gloves, and chemically resistant aprons were required during wet chemical processing and when handling chemicals. Housekeeping and maintenance were performed as needed. The authors conclude that mask production is the only work environment in the company that could present a potentially harmful situation for the worker. They recommend that the company not be considered for further assessment; no information can be obtained that cannot be obtained at larger facilities of the same type.
