Federal Register. / Vol. 51. No. 119 / Friday, ]une 20, 1966 / Rules and Regulations_______ 22769 d. Moving head up and down (UD). Standing in place, the subject shall slowly move his/her head up and down between the extreme position straight up and the extreme position straight down. The head shall be held at each extreme position for at least 5 seconds. Perform for at least three complete cycles. e. Reading (R); The subject shall read out slowly and loud so as to be heard clearly by the test conductor or monitor. The test subject shall read the "rainbow passage" at the end of this section. f. Grimace (G). The test subject shall grimace, smile, frown, and generally contort the face using the facial muscles. Continue for at least 15 seconds. ' 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. fogging in place (J). The test subject shall perform jog in place for at least 30 seconds. i. Normal Breathing (NB). Same a9 exercise a. Rainbow Passage When the sunlight strikes raindrops iri the air. they act like a prism and 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 shove, and its two ends apparently beyond the horizon. There is. according to legend, a boiling pot of gold at one end. People look, 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 shallbe 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 teat 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 of 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 peak concentration for an exercise may be deterinined 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 subject shall nbt.be permitted to wear a half-mask or full facepiece mask if the minimum fit factor of 100 Or 1.000, respectively, cannot be obtained. If hair growth or apparel interfere With b satisfactory fit; then they shall be altered or removed 90 as to eliminate interference and allow a satisfactory fit If a satisfactory fit is still not attained, the test subject must use a positiverpressure respirator such as powered air-purifying 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 tests, 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 QNFT 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/canisters 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 effected, quantitative fit testing shall & 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. 11. Recordkeeping. A summary of all test results shall be maintained 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 respirotor tested (indicate manufacturer, model, size and approval number).
