Badley ( Manager Maintenance Technology Center 49 Building / 7^ 1 , ' CLARIFICATION OF INSULATION PROCEDURES Due to the fact that there have been a few misinterpretations as to what we are doing and what we are trying to accomplish in the way of new insulating materials here at Midland, perhaps a few state ments will clarify the situation. e First and foremost, for health reasons our intent has been to elim inate as many asbestos-containing materials as possible. In the low temperature, range (100 - 350F.) we have done this by c substituting Fiberglas insulation for Aircell. In the medium temperature range (400 - 1500F. ) we are proposing the use of Careytemp 1500 instead of Kaylo. Unfortunately, at the present time, there is no asbestos-free material available for tempera tures above 1500F. The same statement is true for mineral wool insulating cements. To protect our people from exposure to asbestos when exposure iB necessary, we are providing and requiring the use of approved types of respiratory equipment. This requirement applies to the removal and mixing of asbestos-containing materials as well as the applies-, tion. ST0001225 RoyW.
