the last actual rescue i attended where SES were required to extricate two patients, one from each car, it took an hour for the first and another hour for the 2nd (rough estimation of times).
My thoughts are - Why didnt they call for back up rescue and why did it take so long to do what seemed to be a faily simple rescue - cut the b pillar out, remove the doors (one car required a roof roll)
but really what is the normal time for this to be carried out? surely not an hour or more
There's a lot of things that can cause an extrication to take a while, so without knowing all the mitigating circumstances surrounding the particular incident, its hard to know how long it should have taken. Such variables as the experience of the crew, the state of equipment, the state of overcrowding, and of course, the state of the casualty all come into effect here.
From what you've said there the time does sound quite outside of the ideal "golden hour"... Then again, what look to be simple rescues can take us a fairly long time too. I know people are going to jump on this instantly, but its a fact of life...
