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 `frv'rr 7.7.1 Full-face masks have been developed with systems for mounting corrective lenses inside the facepiece.

Keeping SCBAa in a warm location between uses (if practical) 7.3.2 A slight negative pressure occurs inside the facepiece of facu-fitting air-purifying respirators (Table 1C). Care must be taken to obtain an effective seal be tween the facepiece and face to prevent inward con taminant leakage.
