The following criteria shall be used to help determine the adequacy of the respirator fit: a Chin properly placed; b Adequate strap tension, not overly tightened; c Fit across nose bridge; d Respirator of proper size to span distance from nose to chin; e Tendency of respirator to slip; f Self-observation in mirror to evaluate fit and respirator position. The taste threshold is noted as ten regardless of the number of squeezes actually completed. A 30 second mask sample followed by a 9 second ambient sample.
