You need to check English Law. Doing everything by the book is no defence in law. You have to do the best that you can, on the day in the circumstances.
Following company procedures is no defence in law.
It's a fact of life you are between a rock and a hard place.
Dammed if you do and dammed if you don't.
As long as you do the best that you can you should be ok.
