Subject BORG WARNER TALC SITUATION
Following your suggestion I talked with John Dement of NIOSH this morning The main points of information
.
that John supplied are
1 The talc being used by Borg Warner is R. T. Vanderbilt's
NYTAL 200
2 Both bulk and airborne samples were taken by the OSHA inspector
3
Their ray and electron microscope examination of the
talc showed no appreciable chrysotile but considerable amounts of tremolite and anthophyllite
4 Their examination of the samples using the industrial hygiene analysis procedure from the OSHA asbestos standard and using the Stender revised definition of a fiber found approximately 40 fibers per cc in the airborne samples
John Dement asked that we keep him apprised of developments
in the talc situation
