you
00:00:06.460 00:00:06.470 welcome to the mine arc systems operator
00:00:09.619 00:00:09.629 training video this short presentation
00:00:12.609 00:00:12.619 will show you how to operate a monarch
00:00:15.769 00:00:15.779 systems coal safe refuge step one remove
00:00:20.800 00:00:20.810 gas monitors break seal on the gas
00:00:24.830 00:00:24.840 monitor storage located on the front
00:00:27.380 00:00:27.390 wall and remove gas monitors if gas
00:00:30.920 00:00:30.930 monitors are not present proceed to step
00:00:33.830 00:00:33.840 two step to open entry door and enter
00:00:38.869 00:00:38.879 airlock before entering the airlock
00:00:41.779 00:00:41.789 ensure it is vacant by looking through
00:00:44.509 00:00:44.519 the portal window if airlock is occupied
00:00:47.569 00:00:47.579 wait until it is vacant and the internal
00:00:50.479 00:00:50.489 door is closed enter the airlock by
00:00:54.020 00:00:54.030 rotating the handles to the vertical
00:00:55.910 00:00:55.920 unlock position make certain to take
00:00:59.419 00:00:59.429 both gasp monitors into the airlock if
00:01:02.149 00:01:02.159 carrying to secure the door rotate the
00:01:05.719 00:01:05.729 handles to the horizontal lock position
00:01:10.420 00:01:10.430 step 3 commence airlock flushing turn
00:01:15.050 00:01:15.060 pilot switch on an open ball valve to
00:01:18.200 00:01:18.210 commence flushing step 4 activate with

00:01:26.630 00:01:26.640 gas monitor from its storage case
00:01:29.200 00:01:29.210 activate with pump gas monitor by
00:01:32.120 00:01:32.130 pulling battery tab then pushing and
00:01:36.080 00:01:36.090 holding the power button place your hand
00:01:40.160 00:01:40.170 over the pump when directed by the gas
00:01:43.039 00:01:43.049 monitor step 5 flush airlock remove the
00:01:48.560 00:01:48.570 4 minute timer from the gas monitor
00:01:50.959 00:01:50.969 holder flush the airlock for 4 minutes
00:01:53.959 00:01:53.969 or until co is less than 25 ppm step 6
00:02:00.319 00:02:00.329 leave with pump gas monitor in gas
00:02:03.800 00:02:03.810 monitor holder

00:05:23.960 00:05:23.970 temperature chart on refuge wall caution
00:05:27.650 00:05:27.660 using additional TC vs when not needed
00:05:30.890 00:05:30.900 will consume additional cooling
00:05:33.350 00:05:33.360 refrigerant and potentially reduce
00:05:35.779 00:05:35.789 scrubber operating time to less than 96
00:05:39.110 00:05:39.120 hours step 14 install and adjust o2 flow

00:07:57.879 00:07:57.889 if carbon dioxide level exceeds 1%
00:08:01.360 00:08:01.370 remove the Marcus orb co2 cartridges
00:08:04.659 00:08:04.669 from the scrubber and replace with new
00:08:06.969 00:08:06.979 cartridges refer to the life support
00:08:09.999 00:08:10.009 settings table for approximate Marcus

00:08:15.809 00:08:15.819 step 16 emergency gas bypass system the
00:08:21.279 00:08:21.289 emergency gas bypass system is a safety
00:08:24.040 00:08:24.050 feature designed to extend the duration
00:08:26.019 00:08:26.029 of the refuge the system must only be
00:08:29.019 00:08:29.029 activated after 96 hours of normal
00:08:32.500 00:08:32.510 operation before activating the system
00:08:35.649 00:08:35.659 the high pressure gauge on the scrubber
00:08:37.870 00:08:37.880 must read below 400 psi or the scrubber
00:08:42.699 00:08:42.709 air flow with altie CVS on must be too
00:08:47.050 00:08:47.060 low to maintain a co2 concentration
00:08:50.319 00:08:50.329 below 1% to activate the system ensure
00:08:54.759 00:08:54.769 all T Seavey's are on open the emergency
00:08:58.480 00:08:58.490 gas bypass valve located on the left
00:09:01.840 00:09:01.850 hand side of the scrubber system rotate
00:09:05.290 00:09:05.300 knob counterclockwise until low pressure
00:09:08.319 00:09:08.329 gauge reads between 30 to 50 psi use the
00:09:13.720 00:09:13.730 lowest pressure that allows gas
00:09:15.670 00:09:15.680 concentration to remain at acceptable
00:09:18.130 00:09:18.140 levels for further information refer to
00:09:21.910 00:09:21.920 general overview and operating
00:09:23.889 00:09:23.899 procedures the most important thing you
00:09:26.949 00:09:26.959 can do now is to make sure your refuge
00:09:29.829 00:09:29.839 is maintained and good operational order
00:09:32.620 00:09:32.630 so in the unfortunate event you need to
00:09:35.380 00:09:35.390 use the refuge you can feel safe knowing
00:09:38.110 00:09:38.120 that it is ready for use this can be
00:09:40.900 00:09:40.910 accomplished through weekly checks and
00:09:42.670 00:09:42.680 regular servicing which can be carried
00:09:45.519 00:09:45.529 out by my narc systems for further
00:09:48.250 00:09:48.260 details or if you have any queries
00:09:50.680 00:09:50.690 regarding the operation of a coal safe
00:09:53.110 00:09:53.120 refuge please contact my narc systems or
