Current schedules of the Bureau of Mines, however, require that eyepieces shall meet the pertinent require ments for impact and penetration specified in the most recent ANSI Z87.1, "Safety Code for Eye Protection." 72 The manufacturer's instructions or precautions of the ANSI standard should be posted with the respiratory device. 7.7.1 Full-face masks have been developed with systems for mounting corrective lenses inside the facepiece.

Thoroughly (hying matk* after cleaning tesung protocols Additional reference* are lilted in section 9. d. Keeping SCBAt in a warm location between uses (if practical) 7.3.2 A slight negative pressure occurs inside the facepiece of facit-fitting air-purifying respirators (Table 1C). Care must be taken to obtain an effective aeal be tween the facepiece and face to prevent inward eontaminant leakage. Also, demand-type air-supplied respirators and demand-type self-contained respirators operate under negative pressure when the waarer inhales. Since some inw ard leakage of contaminant may be possible, these types provide less protection. When purchaiing new air-supplied, self-contained or combination type, pressure demand should be specified. 7.4 A pressure-demand type self-contained respirator or .
