A total of 7 air samples were collected on filterVphper^afld then ?"
the asbestos was determined using a phase contract microscope at :-Hav
430x magnification (method used is recommended by NlOjSir).

Samples 1, 3- an^T were personnel samples and represented the work--

Krasula. 'Sample.-#5 was taken in the dynamometer lab prior to Mr. -.ft; :
Willettsa cuttihg^and sanding of a small piece of asbestos. Sample
#6 was\taken "at;'the same location as #5 during the cutting and

sanding operation. Sample #7 represents the air concentration dur- -;\-
ing^'tiie.^actual cutting and sanding operation. Visually it. appears ;i.,
that mo|^. of the dust was generated during the sanding (belt sander) 4L operation. Mr. Willetts, performed the sanding outside of the vent-fif-T
ed ateQ in an attempt to duplicate previous levels. If the sand- 401?:'
ingJWas performed inside the vented area it would have resulted in.
imich lower levels on samples 6 and 7.

The current limit for asbestos is 5 fibers/cm^y5.0u in:length.
This is a time weighted limit based on an 8 hour ayf^ageJeixpbsure. On July 1, 1976 this limit will be reduced to 2 fibarg/>0f|3 ^'0u*
Under the current limit and based on the 2 fiber a^3^i$|Ljrie weight
ed limit) the sample results indicate the air*cpncenbt&tions are
acceptable. The sample #7 represents the aiic. cqncenjbratioh during i
the complete operation which only lasted .;14 hunutei thus on a time
weighted average Mr. Willetts exposure^wouid be Well under 2 fibers
/era*'. In addition this sample was
withAtfte grinder outside >
of the vented area. This was done^td"}determihe previous air levels prior to the venting of the sanderi.V Alljftrture grinding should be J?
performed in the vented area, /'' a '" C'C**'
-.
it should be pointed out that .. the limits for asbestos will become .2 fibers/cm^ in July 197S^ii& tija|.va; proposed further reduction
(Oct. 9, 1975 29.CFR 1910,.lObl 1* i^, being considered. The proposed
limit Would reduce the 'level, ter fiber per cubic centimeter for
an 8 hour time ~ weighted^aUebage with a ceiling-limit of 5 fibers
/cm^ over a 15 minute" perio,d.
