Industrial Hygiene, Page I 1. Have you elected to have the respirable asbestos fiber sampling and/or counting done by non-Alcoans or by Alcoans? Discuss. To be performed by an Alcoan. Asbestos fiber sampling and counting is done by a Technician assigned to Environmental Control. 2. Has the initial workplace environmental monitoring survey been conducted? If not, discuss. There is one location where asbestos containing material (marinite) is worked. This work is performed irregularly and' the area was monitored in November, 1972. Other areas are checked upon notification by the maintenance department. Checking has also been done in pot repair building during Hi-Temp* cutting and pot shell dumping. *A11 future purchases will be either Skamel or asbestos-free Hi-Temp. 3. Has the initial personal monitoring survey been conducted? First personal monitoring survey made November 27, 1972. Copies of all survey reports attached. Casting and potroam usage and exposure is generally of such short duration as to make meaningful measure ment impractical. As we are notified of an exposure an attempt at 4. Does^ouf' jfLanie*have the specified sampling equipment for both types of surveys? (Regulation does not seem to specify a difference.) Presently four Monitaire pumps are available. Adequate supply of membrane filters is available. 5. If you plan to conduct the surveys and/or count fibers with your own people, are they presently capable? If not, what are your plans for reaching competency? Yes, the technician is capable. He is also signed up to attend the "Sampling and Evaluating Airborne Asbestos Dust" ftjurse presented by the Environmental Management Branch, Division of Training of the Department of Health, Education and Welfare, on June 26, 27, 28, 1973, in Cincinnati, Ohio.

Estimate the man-hours necessary to conduct your next survey, including counting. Approximately 12 hours per month (average two hours total1 per sample). 8.. As a result of. your observations and/or tests, have you identified areas which exceed the current standards? 1976 standard?
