Try 155.2800 PL 141.3. It's listed as "Emergency Services" but I remember a list somewhere it said "Nutley Haz-mat". I just looked through my spreadsheet and didn't find it! The Essex County fire frequency is 470.5125 pl of 82.5
Even though Haz-mat is separate from EMS and the FD I would think they would operate on their frequency since the FD would be dispatched first and then Haz-mat. Please post what you find.. Now I'm curious!
Justin I think they use Alpha Pagers. Ive never heard Ridgewood ESU get toned out over anything nor have I ever seen thier members with Minitor pagers.
