11. Fully extend the straps of the head harness by grasping the head harness buckles
and extending the head harness straps. Don the S9 and S9 Incurve mask by
grasping the lower two head harness straps and pulling the head harness over
your head. Ensure the mask is properly tted on your face with the chin positioned
in the chin cup. Pull down the back tail of the head harness to position the head
harness properly and check that no straps are twisted. Moderately tighten the
head harness straps by pulling straight back, not out, beginning with the lower
two straps rst, the upper two straps next, and then the top center strap. Readjust
if necessary.
IMPORTANT! THE S9 AND S9 INCURVE FACEMASK IS AVAILABLE IN FOUR SIZES: SMALL, MEDIUM, LARGE, AND
X-LARGE. THE STANDARD SIZE FACEMASK IS THE LARGE SIZE. THE S9 FACEMASK IS AVAILABLE WITH EITHER A
FABRIC HEAD HARNESS OR A RUBBER HEAD HARNESS. CONTACT INTERSPIRO AT (800)-468-7788 FOR MORE

NOTE! OSHA 1910.134 MANDATES ANNUAL FIT TESTING AND ALLOWS THE USE OF EITHER QUANTITATIVE
OR QUALITATIVE FIT TEST METHODS. NFPA 1500, STANDARD ON FIRE DEPARTMENT OCCUPATIONAL SAFETY
AND HEALTH PROGRAM, 2013 EDITION REQUIRES FIT TESTING OF SCBA FACE MASKS AND ONLY ALLOWS
QUANTITATIVE FIT TESTING. INTERSPIRO RECOMMENDS THAT QUANTITATIVE FIT TESTING BE USED AS THE BEST
AND MOST RELIABLE TEST METHOD. FIT TESTING MUST BE ACCOMPLISHED PRIOR TO USING THE SPIROMATIC
S SCBA AND ANNUALLY THEREAFTER. THE OSHA FIT TESTING REQUIRES TESTING IN THE NEGATIVE PRESSURE
MODE AND THE S9 AND S9 INCURVE MASK REQUIRES THE USE OF AN INTERSPIRO FIT TEST ADAPTER P/N
95991-01. CONTACT INTERSPIRO AT (800)-468-7788 FOR ADDITIONAL INFORMATION.

harness if necessary.
13. Check operation of the by-pass by opening the valve and ensure a good ow of
air into the face mask. Close the by-pass.
