hmmm...
well the priority is for us to protect life and property....
so i dont really think we need to worry about it. obviously if theyre was actually a fire, it wouldnt matter how dirty your boots were(for instance), but maybe some thought about making as little impact as possible would be necessary if it was a false alarm and just needed to be investigated...
on the other hand though... in theory we should be wearign BA and dragging a charged hosline to investigate every fixed alarm we go to....
