Ui) Powered air purifying respirators. A full facepiece powered air purifying respirator, or a powered air purifying respirator, or a respirator described in subdivision 'iii) of this subparagraph, shall be used to reduce the concentra tions of airborne asbestos fibers in the respirator below the exposure limits pre scribed m paragraph tb) of this-section, when the ceiling or the 3-hour time- weighted average concentrations of asbestos fibers are reasonably expected to exceed 10 times, but not 100 times, those limits. (iii) Type "C" supplied-air respirators, continuous (low or pressure-demand class. A type "C" continuous Sow or pres sure-demand. supplied-air respirator shall be used to reduce the concentra tions of airborne asbestos fibers in the respirator below the exposure limits pre scribed in paragraph * b) of this section, when the ceiinig or the 8-hour time- weighted average airborne concentra tions of asoestos fibers are reasonably expected to exceed 100 times those lhiuts.
