The individual results of this survey are listed on the attached data sheets opposite the corresponding job description. All determinations of airborne asbestos fiber concentrations were made by the Chrysler Corporation Industrial Hygiene Laboratory using the OSHA dictated membrane filter method at a magnification of 4J0X with phase contrast illumination. Air sample (2) was found to be in excess of the OSHA asbestos ceiling concentra tion of 10 fibers per cubic centimeter of air. The affected employee supplied both the inner and the outer Bendix Corporation disc brake shoes to those employees on the west assembly line who performed the actual assembly opera tion. Air sample (2) was obtained over a relatively short time period while the exposed employee stacked Bendix Corporation inner disc brake shoes obtained from a skid which was grossly contaminated with loose asbestos dust. Air sample (l)i which was obtained from the same employee was found to be within the current OSHA standard of 5 fibers/cc, but in excess of the July 1 1976 OSHA standard of 2 fibers/cc. It should be noted that air sample (1) is considered more indicative of this employees eight-hour time-weighted average exposure because it was obtained over a longer time period than air sample (2). In regard to air sample (2) Mr. T. Duress* letter dated January 30 1976 ful filled the plant's obligation under Section 1910.93a Asbestos (i) (3) nployee Notification) of the OSHA Rules and Regulations by informing the affected employee of his exposure and by notifying the employee of the action taken to correct the condition contributing to his exposure. As a temporary control measure employees were equipped with personal protective equipment in the form of air-purifying type respirators. This type of respiratory protection is considered permissible for airborne concentrations of asbestos fibers which are not expected to exceed the current limit by a factor of can (currently 50 fibers/cc). In a February 4 1976 meeting attended by Messrs. S. Christian W. Proctor R. Wooley A. Brooker, T. Duross, C. Anderson A. Finch E. Kolacki, and the writer the results of the air samples obtained on January 21 1976 ; were discussed. At that meeting we were assured by the attending Bendix personnel that the condition of the skid which was tested on January 21 1976 reprasenced an abnormal situation and that steps would be taken to prevent >a similar recurrence of gross contamination of Bendix disc brake shoes with loose asbestos dust (see attached letter). Subsequent tasting of parts supplied under "normal conditions" conducted on February 4, 1976 indicates Chat the "normal" disc brake shoes did not pose a serious health threat cWWStEB 0*2458 R. R. Noraandin ASBESTOS SURVEY - 2 - February 13, 1976 co Chrysler personnel These results also indicated that resplracory protective devices would no longer be mandatory at the stock supply work stations in Department 9847. While it is evident that present and future OSHA maximum allowable limits were not exceeded under the February 4, 1976 test conditions, Industrial Hygiene reconmends chat plant safety personnel monitor the condition of incoming brake shoe parts for excessive contamination wich loose asbestos dust. If the parts appear to be grossly contaminated wich loose asbestos dust, Industrial Hygiene will monitor tne work environment in order co determine whether the airborne concentration of asbestos dust exceeds safe levels. In addition, an asbestos survey will be performed by the Industrial Hygiene Department at the Toledo Machining Plant on a semi annual basis. ha Attachments cct C. V. Anderson A. S. Brooker T. P.

Boot 1919 Detroit, Michigan W 2 3 1 Dear Mr. Glazier: Confirming our meeting and conversation of Wednesday, February k,1976, pertaining to asbestos dust on the shoe and lining assemblies supplied to the Chrysler Toledo Machining Plant by the Bendix Corporation, Hydraulics Division. The box of shoe and lining assemblies contaminated vlth excessive asbestos dust represents an abnormal condition. I have never seen assemblies in our Plant covered with that amount of loose absestos dust. Corrective actions are being taken that should help to prevent recurrence of this condition.
