Midget loplnger; bated upon a count of airborne partlclea collected by the nidget laplnger aethod aa deacrlbed In Appendix 1. Time-weighted average (WA) eapoaure for an 8-hour work day. Peak concentration determined by a alnimua aaapllng tine of 10 mlnutea. (b) Sampling Procedures for sampling, calibration of equipment and analyals of asbestos samples.by either the Membrane Filter or Midget Implnger Methods, shall be aa described In Appendix 1. Atmospheric monitoring records shall be kept at least three years. Section 2 - Medical Medical surveillance shall be exercised aa described on all workers exposed to airborne asbestos particulates. For the purpose of this requirement the term 'exposed to airborne asbestos particulates refers to exposures attaining 20 percent of the limits listed In 6ectlon 1 for various types of asbestos. The primary objective of this surveillance is to accumulate reliable exposure response data. A secondary objective la to provide guidance for medical mana gement of individuals vltr. t,..ow evidence of reaction to past exposure, either due to excessive exposures or hypersusceptlblllty. However, It Is acknowledged that the current state of medical knowledge stay not permit successful medical management of such cases beyond therapy for complications of ailments associated with asbestos exposure. Medical survellance cannot be a guide to adequacy of current controls when medical and environmental data cover only the recent work experience because of the prolonged exposure required for the manifestation of sympthoms related thereto. Required components of a medical survellance program include annual measurements of pulmonary function Including; forced vital capacity (FVC), and forced expi ratory volume for one second (FEV.), and annual chest roentgenograms (posteroanterlor 14 x 17 inches). Additional medical requirement components Include a history to quantify .taking habits and to describe details on past exposure to pulmonary hatards and carcinogens, and to determine the presence of absence of pulmonary, cardiovascular, and gastro Intestinal sympthomB. A physical examination constitutes and additional required component of medical survellance, with particular attention to pulmonary rales, and clubbing of fingers. Chest roentgenograms (X-Rays) and pulmonary function tests will be performed at the employer's expense annually. Preplacement medical examinations and medical examinations on the termination of employment of exposed workers are also required. 8005 1259 PRODUCED BY FORD
