Good points all.
IT is also important to note that oftentimes, the suppression crews' heads are somewhere else.
The closest I've ever come to getting T-boned in an airplane was by a heavy air tanker operating out of a VERY busy uncontrolled field in VERY restricted visibility, and he wasn't using the CTAF, cause he was too busy chatting on tactical frequency with the lead.
My experience with the fire suppression folks is that the helicopter guys are absolutely straight shooters--always use CTAF's, really pay attention to other aircraft in the area, etc.
Sometimes, it seems like the heavy air tanker guys take the attitude that everyone else should get the heck out of their way. At least that's been my experience, and I know of several near mid airs that occured because the tanker wasn't using CTAF. In one of those, a Navajo was the other aircraft, on an instrument approach.
The last couple seasons, I've spent a fair bit of time around the CL 215 guys, and those guys seem to really have it together--very conciensious, they seem to use CTAF's religiously, and they are always looking for traffic. Two years ago, I worked in among three of those guys, doing a project (I was working my project, and they decided to use the lake I was working around). They got in touch with me, got me a discrete frequency from air attack, and we worked in VERY close proximity until I decided it was way more interesting to sit on the water and watch the show. While it got really busy, those guys were on top of it all the time, and happy to work with me.
I agree fully that we all should stay away from a fire, whether there's a TFR declared or not.
On the other hand, if you are operating to, from or around a tanker base, be extra vigilant, cause, as I say, sometimes those folks' attention is somewhere else.
I hope nobody goes off on that comment, cause it's not necessarily intended as a severe criticism. I've been on the other end some, and I can tell you that communications in this environment can get busy.
Just some thoughts. Keep your eyes open, and don't assume anything.
