Asbestos Survey - Departments 78, 80. and 81
As required by Section 1910.93a, Asbestos, promulgated in the'OSHA standards, a semi-annual survey was performed by the writer on February 6 and 7, 1973, to determine airborne concentrations of asbestos dust. Environmental and personal monitoring were performed as required by this regulation. Results obtained during this survey are listed on the attached data sheet.
Discuss ion
The OSHA standard states that the eight hour time-weighted average airborne concentration of asbestos fiber to which any employee may be exposed shall not exceed five fibers, longer than five micro-meters, per cubic centimenter (cc; of air. On July 1, 1976, a limit of two fibers per cc will become effective. As indicated by the data all fiber con centrations were below both the present and future require ments , therefore , no corrective action is required.
At the time of this survey we were informed that the Centrispray wet dust collector will be replaced by a dry bag type collector, having an 8000 to 8500 cubic feet per minute capacity.
The 1910.93a Section stipulates that asbestos waste be collected
and disposed of in sealed, impermeable bags or other closed im
permeable containers. Caution labels must be affixed to all
waste asbestos containers and to the dust collector clean out
door.
'
Respiratory protection will be required for employees removing bags of waste material from the dry type dust collector. The continuous flow air line respirator (NPSP-226) is the type needed for this operation. Respirators must be cleaned and sanitized as described in the Corporate Respiratory Protec tion Program. The air line supplying this respirator must be

tested for carbon monoxide gas concentration on a monthly basis. Records must be kept indicating the results of these te sts.

Subject:
Asbestos - Department 78
Because of the promulgation of an asbestos emergency standard by the U. S. Department of Labor on December 7, ]971, the atmos phere in Department 78 was sampled by the writer on January 21 , 1972, for the purpose of determining asbestos levels. Previously, airborne concentrations of asbestos dust were determined at five brake shoe grinders in this department on December 15, 1971 and the most recent survey was performed to obtain additional data. One of the requirements of the emergency standard is that per sonal monitoring be performed. Thus, the results and the names of employees whose work environments were evaluated are listed on the attached data sheet. Results of the December 15 survey are also listed.
Discussion
The emergency standard has established a threshold limit value for asbestos dust of 5.0 fibers greater than 5 microns in length per milliliter of air. As indicated by the results obtained during the two surveys, the asbestos dust concentrations at all work stations sampled were below the threshold limit value. Fiber counts ranging from 0.2 to 3.9 fibers per milliliter of air were obtained.
Since the standard stipulates that asbestos dust shall be removed by vacuum cleaners only and that asbestos waste and scrap shall be collected and disposed of in sealed bags or other closed con tainers, it is recommended that all air blow-off guns be removed from the brake shoe grinding machines and that vacuum cleaners be utilized to perform cleanup operations.
