PLAINTIFF'S EXHIBIT CAP-1804 INTRODUCTION: In the control of occupational diseases and injuries caused by breathing air contaminated with harmful dusts, fumes, mists, gases or vapors, the primary objective should be to prevent air from becoming contaminated. This should be accomplished as much as possible by engineering controls. However, there may be circumstances in which applied engineering controls will not be practical or sufficiently effective. Protective respirators will be needed for these situations; either as primary means of control or as a supplement to other primary controls. DEFINITION AND CLASSIFICATION: Although by definition a "respirator" is any device used for providing respirable air, the use and connotation of the word "icspir.uor"h.is become both more specialized and variable. In order to promote greater uniformity in the name of the various devices that appear in the market and to provide a basis for a dearer understanding of the operating principles and uses of these devices, the U.S. Bureau of Mines and the American Standards Association have published standard definitions and classifications for respiratory protective devices. Respiratory protective devices arc grouped broadly according to their method of functioning. The basic classifications are: AIR-PURIFYING RESPIRATORS. Paniculate - removing (mechanical filter) type Gas - and vapor - removing (chemical cartridge) type Combination of the above ATMOSPHERE-SUPPLYING RESPIRATORS Hose-type atmosphere - supplying respirators Hose mask Air line respirator Continuous flow type Demand type Self-contained breathing apparatus Recirculating type Damand type SELECTION AND USE: The use of respiratory protective equipment is justified only after a consideration of the factors involved indicates that the device selected will provide satisfactory protection when properly used. Selection of the proper type of respiratory protective equipment should be based on the following procedures: Identification of the substance or substances against which protection is necessary. Determination of the hazards and significant physical properties of each substance. r. CAPCO JEN 0004653 -2Determination of the conditions of exposure and the concentrations of air contaminant which may be expected. Determine whether any human capabilities and limitations pre essential to the safe use of the devices, i.e., restriction of movements. Fit the respirator carefully and instruct the worker in its use. Practically all applications of respiratory protective devices are specific and require individual attention. However, a classification of principal kinds of exposures and the preferred type of respiratory device is given in Figure 1. FIGURE 1 1.

Not all respiratory protective devices meet USBM requirements. Select USBM tested and approved equipment. Such equipment conforms to OSHA requirements. Examples of USBM approval labels are shown in Figures 3 and 4.

Training in the use of any respirator should cover the following: 1. Instructions in the nature of the hazard, whether acute, chronic, or both, and an honest appraisal of what may happen if the respirator is not used. 2. Discussion of why this is the proper type of respirator for the particular purpose. 3. Description of its construction, operating principles, and limitations. 4. Instruction in fitting the respirator properly and checking for adequacy of fit. 5. Instruction and training in actual use of the respirator and close and frequent supervision to insure that it continues to be properly used. An important by-product of training is the sense of confidence that the employee should develop in his ability to use the respirator properly. CAPCO JEN 0004-656 I .-S-. MAINTENANCE AND CARE: A program for maintenance and care of respirators should be based on the type of plant, working conditions, and hazards involved. All maintenance programs should include the following: 1. Regular inspection for defects (including a leak check) 2. Cleaning and disinfecting procedures 3. Repair responsibilities and facilities I. Proper storage facilities Equipment must be properly maintained to retain it's original effectiveness. INSPECTION: Respiratory protection is no better than the respirator in use, even though it is worn conscientiously. Frequent random inspections should be conducted by a qualified individual to assure that respirators arc properly selected, used, cleaned and maintained. Standards regarding respiratory protection enforced under the "Occupational Safety and Health Act of 1970" are quite extensive and outline specific requirements for certain operations. These should be reviewed whenever a respirator program is planned.
