REGULATOR CHECK
NOTE
THIS REGULATOR CHECK IS NOT INTENDED TO BE A COMPLETE FUNCTIONAL
CHECK OF THE RESPIRATOR.
BEFORE NEXT USE, PERFORM A REGULAR
OPERATIONAL INSPECTION AS DESCRIBED IN THE USE INSTRUCTIONS.
1. Check to make sure the respirator cylinder is at least 1/4 full.
2. Verify that the donning/air saver switch is fully depressed.
3. Close the purge knob.
4. Reattach the regulator to the respirator, (if removed for cleaning).
5. Slowly open the cylinder valve at least one (1) full turn.
6. If air flow from the regulator is heard, close the cylinder valve, repeat steps 1, 2 and 3.
If air flow is still heard, close the cylinder valve fully, tag unit for repair and remove
from service.
7. Open the purge valve and observe the air flow from the regulator spray bar. Droplets
of water indicate the regulator is not dry. Dry the regulator according to Step 7 of
PROCEDURE FOR CLEANING THE MASK MOUNTED REGULATOR section and re-
peat the REGULATOR CHECK.
In step 3 of the
CLEANING THE MASK MOUNTED REGULATOR
instructions (above),
SCOTT instructs the user to inspect the interior of the regulator assembly and if exces-
sive dirt or soil is present to forward the regulator to SCOTT authorized personnel for
thorough cleaning.
RECOMMENDATIONS
SCOTT Operating and Maintenance Instructions provided with each SCBA recommend:
“
Respirators in regular use must be inspected at the start of each use period and
during cleaning after each use. Respirators maintained for emergency use must
be inspected at least monthly or as frequently as required to assure the respirator
will function properly when required
.”
SCOTT is recommending users have their CBRN SCBA’s inspected and tested annually
to ensure proper operation. This recommendation is in addition to the routine daily, weekly,
monthly inspections recommended in the User Manual and is consistent with the recom-
mendations in NFPA 1852 –
Standard on Selection, Care, and Maintenance of
Open-Circuit Self-Contained Breathing Apparatus (SCBA).
SCOTT is separately notifying its authorized service centers that during this annual pro-
cedure, the CBRN regulators be partially disassembled, cleaned thoroughly, inspected,
reassembled and tested to make sure the performance of the SCBA meets SCOTT speci-
fications and instructions.
If you have any problems with the regulator, such as improper release of the air saver
switch or sensing the outside atmosphere through the regulator, put the SCBA aside and
do not use it. Tag it out for maintenance by a SCOTT Authorized Service Center. If you
have any questions, contact your SCOTT Authorized Service Center or SCOTT Technical
Service at 1-800-247-7257.
