In our complex we have made up sets of security fobs and master keys and dropped them off at the three local fire stations. The NSW Fire Department have good processes in place whereby when a call comes through from a strata or commercial complex, if there are keys registered and kept at that station, the fire fighters are alerted to this and they grab them on the way to the trucks. We left them (registered) at all likely fire stations to respond to us.
We had a resident who was very concerned that ambulance / police would not be able to reach them (locked front complex door and a secure lift) in case of emergency. We inquired if the same process as done with the Fire Dept could be done with Police and Ambulance, and was told no. As in many cases the police or ambulance unit that responds is already on the road, it is not practicable for them to collect the keys either timing or process wise.
We have a contractors key safe at our complex. We asked if we could provide the code to police / ambulance for this as a work around, and was also told no, there is no where for this information to be stored.
I am unsure who would have the liability to pay for a knocked down door in case of emergency, but when it comes down to it, if they need to respond in a life threatening situation, who pays for the door would be least of my concerns!
