RE: ASBESTOS USE AT ROCKDALE
Attached is an updated copy of an inventory of Rockdale's asbestos use. The inventory reflects the deletion of three items that appeared on the 1978 August list. These are:
1. Thermocouple wire with asbestos insulation
7t-*T7etC~ C) Replaced with impregnated braided fiberglass insulation
2. Electrical wire with asbestos insulation
/&6Ctf3S. TVS (^6* Specify Rockhide instead of asbestos
3. Asbestos rope - 5/8" and 1" diameter
t h aj s Af
t i-ue-
Replaced with JM Thermopac 2300 ceramic fiber rope
Trials of replacement materials for Marinite and for asbestos mittens are undepway. Also, an unsuccessful attempt to use a non-asbestos insulating material instead of ebony asbestos for the new pot covers was made.
Most of the items remaining on the list are packing and gasketing items which are felt to have an extremely low health hazard potential.
Our major efforts continue to be directed at mittens and Mari nite. No effort is being made locally to find a substitute brake lining material or transite potroom fume duct.

Should be answered In lig h t o f currently available inform ation. A producti f w ill be considered capable of
generating s ig n ific a n t airborne concentrations of asbestos fib e rs the measured or estimated fib e r con
centrationsI t are In excess o f 0.1 fib e r per cc (eight-hour time-weighted average). In responding to this
question, w ill be necessary to consider the p o s s ib ility o f dust being generated not only during instaV
la tio n , but also during use and, where applicable, dismantling.
