22746 Federal Register / Vo1. 51, No. 119 / Friday, June 20, 1986 / Rules and Regulations g. Bend over and touch toes (B). The test < subject shall bend at the waist and touch toes and return to upright position. Repeat for at least 30 seconds. h. Jogging in place (}) The test subject shall perform jog in place for at least 30 seconds. i. Normal Breathing (NB). Same as exercise a. Rainbow Passage When the sunlight strikes raindrops in the air, they act like a prism snd form a rainbow. The rainbow is.a division of white light into many beautiful colors. These.take the shape of a long round arch, with its path high above, and its two ends apparently beyond the horizon. There is, according to legend, e boiling pot of gold at one end. People took, but no one ever finds it. When a man looks . for something beyond reach, his friends say he is looking for the pot of gold at the end of the rainbow. 6. The test shall be terminated whenever any single peak penetration exceeds 5 percent for half-masks and 1 percent for full facepieces. The test subject may be refitted and retested. If two of the three required tests are terminated, the fit shall be deemed inadequate. (See paragraph 4.h.) 7. Calculation of Fit Factors. a. The fit factor determined by the quantitative fit test equals the average concentration inside the respirator. b. The average test chamber concentration is the arithmetic average of the test chamber concentration at the beginning and of the end of the test c. The average peak concentration of the challenge agent inside the respirator shall be the arithmetic average peak concentrations for each or the nine exercises of the test which are computed as the arithmetic average of the peak concentrations found for each breath during the exercise. d: The average peakconcentration for an . exercise may be determined graphically if there is.not a great variation in the peak concentrations during a single exercise. 8. Interpretation of Test Results. The fit factor measured by the quantitative fit testing shall be the lowest of the three protection factors resulting from three independent tests. 9. Other Requirements. a. The test Bubject shall not be permitted to wear a half-mask or full facepiece mask if the mirtimum fit factor of 100 or 1,000, respectively, cannot be obtained. U hair growth or apparel interfere with a satisfactory fit. then they.shall be altered or. removed so as to eliminate interference and allow a satisfactory fit. If a satisfactory fit is still not attained, the test subject must use a positive-pressure respirator such as powered air-puTifying respirators, supplied air respirator, or self-contained breathing apparatus. b. The test shall not be conducted if there is any hair growth between the skin and the facepiece sealing surface. c. If a test subject exhibits difficulty in breathing during the testa, she or he shall be referred to a physician trained in respirator diseases or pulmonary medicine to determine whether the test subject can wear a respirator while performing her or his duties. d. The test subject shall be given the opportunity to wear the assigned respirator for one week. If the respirator does not provide a satisfactory fit during actual use. the test subject may request another ONFT which shall be performed immediately. e. A respirator fit factor card shall be issued to the test subject with the following information: (1) Name. (2) Date of fit test. (3) Protection factors obtained through each manufacturer, model and approval number of respirator tested. (4) Name and signature of the person that conducted the test. f. Filters used for qualitative or quantitative fit testing shall be replaced weekly, whenever increased breathing resistance is encountered, or when the test agent has altered the integrity of the'filter media. Organic vapor cartridges/caniaters shall be replaced daily or sooner if there is any indication of breakthrough by the test.agent. 10. In addition, because the sealing of the respirator may be affected, quantitative fit testing shall be repeated immediately when the test subject has a: (1) Weight change of 20 pounds or more, (2) Significant facial scarring in the area of the facepiece seal, (3) Significant dental changes; i.e.. multiple extractions without prothesis, or acquiring dentures. (4) Reconstructive or cosmetic surgery, or (5) Any other condition that may interfere with facepiece sealing. . ll. Recordkeeping. A summary of all test results shall be maintained in for 3 years. The summary shall include: (1) Name of test subject. (2) Date of testing. (3) Name of the test conductor. (4) Fit factors obtained from every respirator tested (indicate manufacturer, model, size and approval number).' Appendix D to 5 1910.1001--Medical Questionnaires; Mandatory This mandatory appendix contains the medical questionnaires that must be administered to all employees.who are exposed to asbestos, (remolite, anthophyllite, actinolite, or a combination of these minerals above the action level, and who will therefore be included in their employer's medical surveillance program. Part 1 of the appendix contains the Initial Medical Questionnaire, which must.be obtained for all new hires who will be covered by the medical surveillance requirements. Part 2 includes the abbreviated Periodical Medical Questionnaire, which muBt be administered to all employees who are provided periodic medical examinations tinder the medical surveillance provisions of the standard. 6SLLINQ CODE 4S10-2S-M GLEASON-000994
