I thought Hazmat was 28...
Brigades previously paged by MFS haven't seen a change of number ie Morphett Vale is still 8124, Happy Valley 8032, not 18124,18032. From what I have seen on the pager site, all the new 5 digit numbers we are seeing simply refer to station number + call type. However, I do see a pattern that all the rural region 1 station numbers seem to start with a 1, region 2 with a two etc Example Sheaoak Log is 229 (Region 2), Yacka 496 (region 4), Naracoorte 562 (Region 5). Burnside is still 29, not 129. All means very little when these numbers cease to be used.
