This example is entirely fictional.
One morning whilst walking to my car, I notice that my elderly neighbour who lives alone is laid out on the floor of her living room.
I knock on the window, but get no response. I bang on the door, still no response.
Then I try the door, and the door is locked so required physical force to open. I kick the door in to find that my neighbour had fallen to sleep watching TV and her hearing aid had ran out of power.
Would I be liable for the damage as a concerned citizen?
