Couldn't agree more about the structural helmet.. As i have said a number of times.. I wont wear a rural, for the simple fact that I dont think they are made well enough, and do not offer as much protection in the case of an impact from above..
MAny will say " But you would probably break your neck anyway".. - but, if you dont, and end up wil half a head ... Then ur knackered...
As long as you understand the heat and thermal protection properties, and understand you need to take it off after 45 mins of active fire fighting, to cool down, then I dont see a problem with it being used for both rural and structural responses..
Its hard explaining to people who have never worn one, why they are so up there when it comes to helmet choice..
Wouldn't wear anything other than my Cairns
