Page 7: What You Should Do
HEADS-UP DISPLAY OPERATION The optional HEADS-UP DISPLAY provides a visual monitor of the air supply in the cylinder and valve assembly. The display is fitted to the facepiece mounted regulator and appears across the bottom of the user's field of view through the facepiece. The HEADS-UP DISPLAY consists of four rectangular lights to represent the cylinder pressure at FULL, THREE-QUARTERS, ONE-HALF, and ONE-QUARTER. - Page 8 AN IMPROPERLY FITTED FACEPIECE MAY minimum) appropriate negative pressure testing equipment must be used. LEAD TO EXPOSURE TO THE HAZARDOUS You should use a P100 Filter, SCOTT P/N 052683 and the SCOTT P/N ATMOSPHERE WHICH COULD RESULT IN 805628-01 Fit Test Adapter.
- Page 9 To verify the fit factor of the respirator, testing must incorporate an exercise regimen of normal daily activities. SCOTT requires the following set of fit test exercises, which are based on OSHA Standard 29 CFR Part 1910.134 Appendix A, and ANSI Z88.10-2001 with modifications.
