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.
