Flats 1-6 Communal Entrance Door – Lock Latch left open – Safety Risk

Please can residents ensure that the entrance door latches to communal areas for Flats 1-6 and Flats 9-12 are kept on the lock setting.  We appreciate that on occasion visitors (medical, delivery, builders) may be coming in and out, however on quite a few occasions the door latch has not been set back to lock setting, leaving the entrance open for a number of hours.  This is a safety risk so please be aware, also a sign is visible asking residents to ensure the latch is set to lock mode.  Thank you.
