Unless Airscan has upgraded recently, he doesn't have a digital capable scanner to listen to any of the RWC sites, including the Sky Harbor IR.
Airscan, just to be clear, the Emergency Dispatch and IMS talkgroups on the Sky Harbor IR are not Emergency Management in the Civil Defense way that you may be thinking of. They're for the use of fire station 19 & 29 apparatus at the airport, (as well as any other off-airport fire apparatus that may respond to emergencies on the airport grounds) and any other authorized airport or fire department staff.
They are mostly used during in-flight emergency incidents, (Alert 1, 2 or 3 incidents) in addition to whichever VHF A-deck channel Phoenix Alarm may assign them to. A-7 or A-8?
