The test shall not be conducted if there is any hair, growth between the skin and the facepiece sealing surface. 17. If 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 mu6t use a positive-pressure respirator such as powered air-purifying respirators, supplied air respirator,.or, self-contained breathing . .. apparatus. 18. If a test subject exhibits difficulty In breathing during the tests, she or he shall be referred to a physician trained in respirator dis$ases.or pulmonary medicine to determine. whether the test subject can wear a respirator while performing her or his duties. 19.

(2) Significant facial scarring In the area of . the facepiece seal, . (3) Significant dental changes; i.e.; multiple extractions without prothesis, or acquiring dentures.
