Following on from the emergency thread... (yes I have let the police in without the washing up being done in the past - no - no one cared...)
If your house was filled with smoke, and you couldn't see or breathe in - could you get out?
This mostly means, can you put your hand on the door or window key right now, with your eyes closed, and does everyone know where to meet up?
( lives have been lost when everyone is safely out, but someone is missing and a relative returns to a burning building to look for them, not knowing they were already safe)
I think this is important - if you have to get out of the house blind, before you next breathe in - do you have an emergency key in a fixed place you can put your hand straight on now without thinking?
