I guess I did.
the first thing you need to change is dispatch, so you can be there. it's a lot easier for you to tell the fire department that you are handling this if you are there with all your crew, with all your equipment, and you are right next to him on the scene ready to go. that should be the FIRST thing.
changing attitudes on scene is a little different. many FD's have problems with police officers running into burning buildings, protected by just their badges and guns, as they attempt to perform a rescue (instead of waiting until the FD gets there). And before anyone asks, yes, nationwide, some LEOs are no longer with us, others had to be rescued by the FD when they got trapped, and others were injured/out on disability after sustaining injuries as a result. The reason I bring this example up is because it demonstrates that you aren't going to change people's opinions when it comes to making a rescue by using logic. There are FF/LEOs who won't do CPR on a 70 year old man, but if it's a 1 year old not breathing, they will beat you to the scene and be on the way to the hospital in the patrol car before you even get dispatched. again, it comes down to that "hero tunnel vision"
Until someone gets lost/hurt/heaven forbid killed, they will still try to do something, and make a rescue. they might lack the training and equipment to do it safely, but it's very hard to stand by and do nothing.
but once you are on scene with them, with your equipment, if they do something stupid and you have to rescue their crews, well, maybe then they will see the light.
