PLAINTIFF'S EXHIBIT BuDiac' Telecommunications Industrial Hygiene Survey Kit AftT Bell Laboratories late January 26, 1985 i>om. Charles P. Lichtenwalner MH 77621 1F-110 X5399 MEMORANDUM FOR FILB This note details procedures for conducting an industrial hygiBne survey using the telecommunications industrial hygiene survey kit. This kit has been assembled to assist safety coordinators to respond to health or environmental complaints by performing a survey of conditions. Hi?'a and procedures for use of the equipment are given in tl ppendices to this memorandum. Appendix A: Equipment and Procedures for Sampling Various Substances Appendix B: Measuring Noise Exposure (OSHA Dose) Appendix C: Calibration and Use of Colorimetric Detector Tubes and Pumps Appendix D: Calibration and Use of Personal Sampling Pumps Appendix E: Wet wipe Sampling Procedures for PCBs Appendix F: Parts List for Telecommunications Industrial Hygiene Survey Kit Additional equipment that may prove useful: 1. A camera (preferably instant) to document conditions. 2. Manuals of equipment and a sampling manual such as this note and the attached exercises from the REOHH courses. 3. Appropriate detector tubes for any gases or vapors to be sampled. LLA 001476 Memorandum for File - 2 Note that the techniques liBted in Appendix A may not always be the best or most accurate methods available but they are usually adequate for screening or to assess the extent of the problem.

Do not use numbered filters - they are PVC. To avoid exposure while sampling take a wet sponge with hole cut in middle same diameter as tube. Press wet sponge against ceiling then insert tube through hole and with screwing motion pierce insulation and cut out a core of material into tube.
